How to set WebService NameSpace in web.config file?

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :ASP.Net

I am trying to put the namespace value as a key in web.config file, so that when I deploy this on production, I just have to change the namespace key in the config file only, not on all of my webservice cs files. But When I try to browse this webservice after changing this code I get compilation error.


    <add key="NameSpace" value="http://csi-dev-deep/"/>

MyWebService.cs (this code works)

[WebService(Namespace = "http://csi-dev-deep/")]

MyWebService.cs code changed to the following gives compilation error.
[WebService(Namespace = ConfigurationManager.AppSettings["NameSpace"].ToString())]

Compiler Error Message: CS0182: An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type

Your help is highly appreciated.

Thank you.

Razor View Engine and Add Namespace in Web.Config Problem



I am working on a MVC project with Razor view engine and I have the following:


This only works if I have on the same view the following:

  @using SquishIt.Framework;

However, on my Web.Config I have the following:


      <!-- Namespaces -->
        <add namespace="System"/>
        <add namespace="System.Web.Mvc"/>
        <add namespace="System.Web.Mvc.Ajax"/>
        <add namespace="System.Web.Mvc.Html"/>
        <add namespace="System.Web.Routing"/>
        <add namespace="Microsoft.Web.Mvc"/>
        <add namespace="SquishIt.Framework"/>


So if "SquishIt.Framework" namespace is added on Web.Config why do I need to have the @using on the view?

How do I find the file path from a namespace.class name?


I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplication\myPage.aspx.vb". Then I use the code below:


Dim Assm As System.Reflection.Assembly = System.Reflection.Assembly.LoadFrom("myApplication\bin\myApplication.dll")
Dim ClassType As Type = Assm.GetType("myApplication\myPage.aspx.vb")
' myBaseType = "myApplication.Forms.BasePage"
Dim myBaseType As System.Type = ClassType.BaseType


Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '\' in order to get the path.

How can I get the path of BasePage so I can read it? Thank you - Frank

Problem when using Activator.CreateObject and reading App.Config file

Hello, this is the scenario. I have an application that load at runtime severals dll. these dll are actually "adapters" that wraps calls to web services, database and so on. The app.config of the "main" application stores in config sections all information necessary to each adapter (i.e.Web ServiceURL..) and I have created inside each adapter a class to ready those values the loading at run time the DLL has been implemented by storing all necessary types into a dictionary of generics and when I need to instanciate it I call the Activate.CreateObject and I pass the specific type (I means the name of the Adapter class) The problem is that the adapter class itself is not able to get the config value because ConfigSection has not been initialized. If I write: IInterfaceAdap adapt = new myAdapter() -> I read the config data IInterfaceAdap adapt = (IInterfaceAdap)Activator.CreateObject (type) -> now way to read the data stored in the App.Config. I think that I undertood the problem but I'm not able to find a workaround to read data store in the app.config!! I need help please!!  

Having issues with the webservice to write file

Is there anything extra I have to do with the webservice. If the aspx page with the upload control writes to the same "uploads" folder, then it works fine. Currently, only the asp.net account is permitted to write to that directory. When the webservice was introduced in it's place, I'm seeing permission issue stating the "Unauthorized" message. What's working: - User goes to .aspx page and use the upload control to upload the file What's not working - User goes to a fat client, and sends the file in a byte array to the webservice - It works if the webservice is on the same computer, but, fails if the fat client is run on a different computer Best Regards, Rajib Bahar http://www.rajib-bahar.com | http://www.linkedin.com/in/rajibb | http://www.twitter.com/rajib2k5

Setting maxItemsInObjectGraph in a WCF REST config file???

Hi All, I am trying to create a new WCF Rest service. I used the online VS2010 WCF REST 4.0 template as a base. I have a service up and running and have been testing it using IE/Firefox (currently it is a read only API, so I have no need to post anything back to the service). I have an issue when the number of items being returned is too large, IE give me a "Internet Explorer cannot display the webpage" I turned on tracing and was able to confirm the issue is with the maxItemsInObjectGraph property (defaults to 65536) <Message>Maximum number of items that can be serialized or deserialized in an object graph is '65536'. Change the object graph or increase the MaxItemsInObjectGraph quota. </Message> Using the defualt WCF Web.config file I have no clue how to set this value as it doesnt seem like a standardEndpoint can have this value set, or have a custom binding or behaviour assigned to them (at least I don't know how to set them). Here is the default web.config file the template created. Does anyone know how i can update/increase the maxItemsInObjectGraph property?      <system.serviceModel>    <diagnostics>      <endToEndTracing propagateActivity="true" activityTracing="true"   &nb

Site File Structure, Folders, Learning project, subweb, web.config

I am just learning asp.net.  I purchased an "ASP.Net 3.5 web programming in C#" book, which I like allot.  I am on chapter 3 and want to complete a shopping cart exercise from the book.  I have to create several folders and files.  The exercise has the files and under the root directory and a few folders below that.  I already have a site that I've been learning on.  Can I create a subfolder on my site and put all the files in there?  Like the subfolder is the root of the project.   Here is list of Folders and files... Code/CartItem.cs Code/Product.cs Data/Cars.mdb Images/car.jpg Cart.aspx Order.aspx Web.config ................................ On my website I want to create a subfolder to keep alll the files in, as so... ShoppingCart/Code/CartItem.cs ShoppingCart/Code/Product.cs ShoppingCart/Data/Cars.mdb ShoppingCart/Images/car.jpg ShoppingCart/Cart.aspx ShoppingCart/Order.aspx ShoppingCart/Web.config ................................ Can I have two web.cong files?, one in the subfolder?  Or do I have to use the single, web.config file in the root directory of the site?  Are there any other pitfalls or trouble I might get into setting up my file structure like this?  Anything I should be aware of? Any thoughts or advice would be appreciated. Thanks, Mike   

How to move PrincipalPermissionAttribute from CS file to app.config?

I'm really struggling with the following scenario: I have a WCF service where the methods of the implementation of my service contract are decorated with one, or many, PrincipalPermission attribute(s). For instance: [PrincipalPermission(SecurityAction.Demand, Role = "Administrators")] [PrincipalPermission(SecurityAction.Demand, Role = "MyGroup_1")] public void DoSomething() { //Work done here } [PrincipalPermission(SecurityAction.Demand, Role = "Administrators")] public void DoSomethingElse() { //Work done here } So in this case, method DoSomething(), could be called by users either members of the "Administrators" group or the "MyGroup_1" group. And only Administrators should be allowed to make calls to DoSomethingElse(). My problem is I want to put this in the app.config file, but I can't find any way to do this. How can I "move" these decorations from my CS file to the app.config?

Placing ..... configuration information in a config file other than app.config

Hi, I'm sorry if this question has been asked/answered before on this forum. I have searched both here and on the web in general, but to no avail as yet... I am running VS2010 and .Net 4, so in theory have all the latest versions of everything at my disposal. I have an executable a.exe. This downcalls into a dll b.dll. b.dll wants to send an MSMQ message using WCF. For cleanness (a.exe is a generic service and knows nothing about WCF) I want to define the client endpoint in b.dll.config. However I am finding that WCF is insisting that the information is held in a.exe.config. The exact problem is that when I create my proxy (i.e. the class which derives from ClientBase<T>), I get the message Could not find endpoint element with name 'XXX' and contract 'YYY' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element. From what I have seen I have just described an extremely common problem that people have had with WCF over the years. My questions is basically to find out, given that I have WCF 4 at my disposal, whether there is now a standard approach to this scenario? Things I have tried so far: The obvious one...putting all my config info in a.exe.config. When I do this, everything works file, so I
