Compiler Error CS0111

Type 'class' already defines a member called 'member' with the same parameter types

CS0111 occurs if a class contains two member declarations with the same name and parameter types. For more information, see Methods (C# Programming Guide).

Example

The following sample generates CS0111.

// CS0111.cs
class A
{
   void Test() { }
   public static void Test(){}   // CS0111
   
   public static void Main() {}
}
