Compiler Error CS0663

  • Artikel

Cannot define overloaded methods that differ only on ref and out.

Methods that differ only on their use of ref and out on a parameter are not allowed.

The following sample generates CS0663:

// CS0663.cs
class TestClass
{
   public static void Main()
   {
   }

   public void Test(ref int i)
   {
   }

   public void Test(out int i)   // CS0663
   {
   }
}
