Compiler Error CS1527

Elements defined in a namespace cannot be explicitly declared as private, protected, protected internal or private protected.

Type declarations in a namespace can have either public or internal access. If no accessibility is specified, internal is the default.

The following sample generates CS1527:

C#
// CS1527.cs  
namespace Sample  
{  
   private class C1 {}             // CS1527  
   protected class C2 {}           // CS1527  
   protected internal class C3 {}  // CS1527  
   private protected class C4 {}   // CS1527
}  

The following example generates CS1527 because when no namespace is explicitly declared in your program code, all type declarations are located implicitly within the global namespace.

C#
//cs1527_2.cs  
using System;  
  
protected class C4 {}  
private struct S1 {}
