Compiler Error CS0262

Partial declarations of 'type' have conflicting accessibility modifiers

This error occurs if a partial type has inconsistent modifiers such as public, private, protected, internal, or abstract. These modifiers must be consistent in all partial declarations for that type. For more information, see Partial Classes and Methods (C# Programming Guide).

Example

The following sample generates CS0262:

// CS0262.cs
class A
{
    public partial class C  // CS0262
    {
    }
    private partial class C
    {
    }
}
