Compiler Error CS0412

'generic': a parameter or local variable cannot have the same name as a method type parameter

There is a name conflict between the type parameter of a generic method and a local variable in the method or one of the method's parameters. To avoid this error, rename any conflicting parameters or local variables.

Example

The following sample generates CS0412:

C#
// CS0412.cs  
using System;  
  
class C  
{  
    // Parameter name is the same as method type parameter name  
    public void G<T>(int T)  // CS0412  
    {  
    }  
    public void F<T>()  
    {  
        // Method local variable name is the same as method type  
        // parameter name  
        double T = 0.0;  // CS0412  
        Console.WriteLine(T);  
    }  
  
    public static void Main()  
    {  
    }  
}
