Is this what you mean? This define an index, default property to a class:

Code:

public class Class1 {
public int this[int index]
{
   get
      {   
          return index;   
      }
   set
      {   
      }
}
}

To use it you can then do this:

Code:

Class1 c = new Class1();
Console.WriteLine(c[i]);

If this isn't what you meant then please explain, perhaps giving an example of the VB code you want to reproduce.

Hi Sam,

I want to create property in c#, in which we can pass arguments like in c# method.

e.g.,

Response.QueryString["id"]

Here QueryString is a property of Response object,and we are passing string into it. I like to create
property like this. Please help with an example.

HttpRequest.QueryString is just defined as a property that returns a NameValueCollection object. Its then the NameValueCollection above that has the this[string] property defined that allows you to do QueryString["id"]. i.e. Response.QueryString["id"] is equivalent to:

Code:

NameValueCollection collection = Response.QueryString;
string id = collection["id"];
