Can multiple catch blocks be executed?

Posted By :Ghanashyam Nayak     Posted Date :September 09, 2010    Points :10   Category :C# 
No, once the proper catch code fires off, the control is transferred to the finally block (if there are any), and then whatever follows the finally block.

Can we have multiple threads in one App domain ?

  
One or more threads run in an AppDomain. An AppDomain is a runtime representation of a logical process within a physical process. Each AppDomain is started with a single thread, but can create additional threads from any of its threads.
Note :- All threading classes are defined in System.Threading namespace. (More...)

Why is catch(Exception) almost always a bad idea?

  
Well, if at that point you know that an error has occurred, then why not write the proper code to handle that error instead of passing a new Exception object to the catch block? Throwing your own exceptions signifies some design flaws in the project. (More...)

How can you cache Multiple Versions of a Page?

  
Using output cache you can cache multiple versions of the page.

We can either use,.

- @ OutputCache directive at design time declaratively for Declarative Approach
OR

- Response.Cacheclass at runtime for Programmatic Approach .

With @ OutputCache directive four parameters of VaryByParam , VaryByControl, VaryByHeader, VaryByCustom allows user to cache page depending on query string, control value, request's HTTP header, request's HTTP header respectively.

For an example:

To turn off caching,

Declarative Approach:
<%@ OutputCache Location="None" VaryByParam="None" %>

Programmatic Approach:
Response.Cache.SetCacheability(HttpCacheability.NoCache);


To cache the output for each HTTP request that arrives with a different ID:

Declarative Approach:
<%@ OutputCache duration="60" varybyparam=" ID" %>

Programmatic Approach:
Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.VaryByParams["ID"] = true; (More...)

Suppose you want a certain ASP.NET function executed on MouseOver for a certain button. Where do you add an event handler?

  
Add an OnMouseOver attribute to the button. Example: btnSubmit.Attributes.Add("onmouseover","someClientCodeHere();"); (More...)

No, If the System.Array is of Some Particular Data Type.(Primitive Data Type)

yes, If the System.Array is of Object Type.

Ex :

create an array of objects.

int in = 50;
string st = "Fifty";

object [] obj = new object[2];
obj[0] = in;
obj[1] = st; (More...)
