Compiler Error CS0158

The label 'label' shadows another label by the same name in a contained scope

A label in an inner scope hides a label with the same name in an outer scope. For more information, see goto (C# Reference).

The following sample generates CS0158:

// CS0158.cs
namespace MyNamespace
{
   public class MyClass
   {
      public static void Main()
      {
         goto lab1;
         lab1:
         {
            lab1:
            goto lab1;   // CS0158
         }
      }
   }
}
