Compiler Error CS1910 

Error Message

Argument of type 'type' is not applicable for the DefaultValue attribute

For parameters whose type is object, the argument of the DefaultParameterValueAttribute must be null, an integral type, a floating point, bool, string, enum, or char. The argument can not be of type Type or any array type.


The following sample generates CS1910.

// CS1910.cs
// compile with: /target:library
using System.Runtime.InteropServices;

public interface MyI
   void Test([DefaultParameterValue(typeof(object))] object o);   // CS1910
