Compiler Error CS0106

The modifier 'modifier' is not valid for this item

A class or interface member was marked with an invalid access modifier. For example:

  • The static and public modifiers are not permitted on interface methods.
  • The static modifier is not permitted on a class.
  • The public keyword is not allowed on an explicit interface declaration. In this case, remove the public keyword from the explicit interface declaration.
  • The abstract keyword is not allowed on an explicit interface declaration because an explicit interface implementation could never be overridden.

The following sample generates CS0106:

// CS0106.cs
namespace MyNamespace
{
   interface I
   {
      void m();
      static public void f();   // CS0106
   }

   public class MyClass
   {
      public void I.m()   // CS0106
      {
      }

      public static void Main()
      {
      }
   }
}
