I static class i have a method called disply().

Solution 1

Unless you have improperly pasted your code, the issue is that you are trying to call a method outside of a method definition in your public class cl1. Here is the way it should look:

C#

public class cl1
{
   public string CallDisplay()
   {
      return cl.display();
   }
}

Solution 2

the cl.display(); in cl1 is not inside a method body.
cl.Display(); in your Program class works because it is part of the Main method.
You should change cl1 so it looks something like this:

C#

public class cl1
{
    public void SomeMethod()
    {
        cl.display(); // Now works fine :)
    }
}
