Compiler Error CS0721

'type': static types cannot be used as parameters

A static type is not meaningful as a parameter. Since no instances of static types may be created, no instance could ever be passed as a parameter.

The following sample generates CS0721:

// CS0721.cs  
public static class SC  
{  
}  
  
public class CMain  
{  
   public void F(SC sc)  // CS0721  
   {  
   }  
  
   public static void Main()  
   {  
   }  
}
