help passing generic list to method

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net

I have several lists in one class. When I add an class/object  to a list I want to be able to check if it doesn't exist already in the list. I've done this using a method that checks the particular list individually but would require a method for each list eg

private bool checkShipList (List<Ship> ship, Ship newship)

//check list code


How can I make it so I use only one method for all lists and can pass the new object to it to check. I used List<T> in the method but can't get it right with the second parameter. Thanks for any help.

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?

TSQL: Passing array/list/set to stored procedure (MS SQL Server)

Passing array/list/set to stored procedure is fairly common task when you are working with Databases. You can meet this when you want to filter some collection. Other case - it can be an import into database from extern sources. I will consider few solutions: creation of sql-query at server code, put set of parameters to sql stored procedure's parameter with next variants: parameters separated by comma, bulk insert, and at last table-valued parameters (it is most interesting approach, which we can use from MS SQL Server 2008). Ok, let's suppose that we have list of items and we need to filter this items by categories ("TV", "TV game device", "DVD-player") and by firms ("Firm 1", "Firm2", "Firm 3). It will look at database like this So we need a query which will return us list of items from database. Also we need opportunity to filter these items by categories or by firms. We will filter them by identifiers. Ok, we know the mission. How we will solve it? Most easy way, used by junior developers - it is creating SQL-instruction with C# code, it can be like this List<int> categories = new List<int>() { 1, 2, 3 };   StringBuilder sbSql = new StringBuilder(); sbSql.Append( @" select i.Name as ItemName, f.Name as FirmName, c.Name as CategoryName from Item i inner join Firm f on i.FirmId =

Navigate through a generic list using a webservice

Hi I have a problem where I would have a dataset coming to me and I would break into 5 new generic LIST<>. Now the user needs to see one record at a time and navigate through the list Fields like               From date : Text box with calendar                To Date : Text box with calendar               Manager Reporting To : Drop down list                Buttons on Move Back  and move Forward Now I would have 4 such similar lists which I have to pick up from the audit table. When the user clicks on move back and move forward buttons he should be able to navigate through records in my list that I have fetched in the beginning . I can store it in a session or viewstate till it gets updated again. How do I achieve this. Can I also a gridview instead of textboxes. What should be the simplest way to achieve this. Thanks!

How to : Generic error handling function. Passing GridViewUpdatedEventArgs as EventArgs

Hi, I want to build a generic error handling function for handling inseted, updated, deleted events from formview, gridview and detail view. I am still a bit new to C# so I have encoutered a simple problem that I cannot resolve and cannot find an answer while searching google.Right now I handle error with validator for generic validation but I need to catch BLL error.I have different event handler for the different type of event : protected void FormView_AjoutCompte_ItemInserted(object sender, FormViewInsertedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } protected void GridView_ListeUtilisateurs_RowUpdated(object sender, GridViewUpdatedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } protected void GridView_ListeUtilisateurs_RowDeleted(object sender, GridViewDeletedEventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.ExceptionHandled = true; } } I want to create a generic function that will handle them all, a function such as : private void GestionDerreur(EventArgs e) { if (e.Exception != null) { Afficher_Erreur(e.Exception); e.Exc

Passing List to WCF Service

Hi, All, I'm not sure this has been covered before.  I did search, but not sure that any of those responses apply: I'm relatively new to WCF. I have the following classes:  PostAddress, EmailAddress, PhoneNumber, ContactInformation and, Person.  The ContactInformation contains each a List<PostAddress>, List<EmailAddress>, List<PhoneNumber> property.  The Person class has a ContactInformation property. When I pass my Person object to my WCF service, my ContactInformation Lists values are null.  For example: I create an address with: street, city, state, zip, country and add it to my List<PostAddress> I add the list to the Person's ContactInformation's List<PostAddress> Property I pass it to the WCF Service.  At that time, I have this: Person.ContactInformation.Addresses.Count = [the number of addresses in the list] Person.ContactInformation.Addresses[index].property = null My service inferface looks like this (I haven't fully sketched it all out yet): [   ServiceContract]     public interface IMyService { [   OperationContract]     bool FoundDuplicate( Person p ); [   OperationContract]     void SubmitNewMembership( Person p, Membership m ); } I'm using Visual Studio Ultimate 2010/.NET 4 on Windows 7 Professional Edition if that

passing messageContract object to a WCF Service method using Soap - not as a method parameter

i want a web application to create a service reference to my WCF service, insert information to the header of the soap call and call my WCF method. my WCF supports soap operations (also there is an endpoint in the config). i read about MessageContract attribute and declared one in the interface file: [ServiceContract] public interface IBasicService { [OperationContract] [WebGet(UriTemplate = "GetData?value={value}")] // Add support for HTTP GET Requests string GetData(int value); } [MessageContract] public class BasicServiceHeader { [MessageHeader] public string myString; } the implementation of the contract : public class BasicService : IBasicService { public string GetData(int value) { return string.Format("You entered: {0}", value); } } i don't want the BasicServiceHeader to be passed as a parameter of GetData function , i want to keep the function signature as it is (without a BasicServiceHeader parameter) and to extract the BasicServiceHeader inside the function, (just like using soapHeader) can i do that ?

Weird casting error (storing Generic list in Session)


Am trying to store a generic list in Session to act as a simple shopping cart. Am getting a weird casting error when I try and retrieve it from Session.

A critical error has occurred.
[A]System.Collections.Generic.List`1[MyCartItem] cannot be cast to [B]System.Collections.Generic.List`1[MyCartItem].
Type A originates from 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'
    in the context 'LoadNeither' at location 'C:\WINDOWS\assembly\GAC_32\mscorlib\\mscorlib.dll'.
Type B originates from 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'
    in the context 'LoadNeither' at location 'C:\WINDOWS\assembly\GAC_32\mscorlib\\mscorlib.dll'.

I have a class variable defined:

List<MyCartItem> _cart;

In the Load event I have:

_cart = (Session["MyCart"] != null) ? (List<MyCartItem>)Session["MyCart"] : new List<MyCartItem>();

Generic List to DataTable



I have a GenericList and i want to convert that to DataTable

objFinOpRegs = CType(queryF.ToList(), List(Of FinOpeningRegisterBranch))

I am getting Count in "objFinOpRegs". But i want to convert "objFinOpRegs " to DataTable.


BCS Method Security / External Content Type Permissions / Custom List Security Provider / Security T


I have an external list setup with the usual CRUD methods.  The external SQL table is also being populated by another source.  I want to enable/disable deleting depending on whether the record was created from SharePoint.  I would also like the normal list permissions to work.  So if a user has permissions to delete on the list, they can only delete items created for SharePoint. 

Where should this logic be incorporated?  On the BCS Delete method, somewhere in the External Content Type or on the list instance?  Most examples I find relate to security trimming for search.  I'm only concerned about the delete method.

I'm sure there are multiple ways to accomplish this.  Which is the best?
