Compiler Error CS1910

  • Article

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.

Example

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
}
