  Generics allow you to define type-safe classes without compromising type safety, performance, or productivity. You implement the server only once as a generic server, while at the same time you can declare and use it with any type. To do that, use the < and > brackets, enclosing a generic type parameter. For example, here is how you define and use a generic stack:

  
  

  public class Stack<T>
  {
    T[] m_Items; 
    public void Push(T item)
    {...}
    public T Pop()
    {...}
  }
  Stack<int> stack = new Stack<int>();
  stack.Push(1);
  stack.Push(2);
  int number = stack.Pop();

  Generic Handlers (*.ashx files) in an ASP.Net application is very different from Generics in C#.  If your question regards ashx files, please ask at http://forums.asp.net.  If you are discussing generics as applies to desktop apps, the others have answered appropriately.

  Hello

  Handlers are used when you want to avoid the overhead of a regular asp.net page Practical examples include image processing or handling ajax requests.

  Generally in ASP.NET we are used to working with .ASPX file most. ASPX file is heart of ASP.NET technology. Basically ASPX file represent HTML kind of representation which used to bind with ASPX.CS file which is largely known as code-behind file. When you run ASPX file, it compiles code-behind and display the results, but, have you ever thought that you could bypass code-behind file?
  
  ASXH (HTTP Handler) is really very powerful but under utilized utility. Even if you search GOOGLE, you won’t find many examples. I tried to GOOGLE this topic and found mostly one example of retrieving images with HTTP Handler.  HTTP Handler is not limited to retrieve images only but it is really VERY powerful tool to use.

  See Here all information about Handler

  Thanks
