Compiler Error CS0655

'parameter' is not a valid named attribute argument because it is not a valid attribute parameter type.

See the Attributes Tutorial for a discussion of valid parameter types for an attribute.

The following sample generates CS0655:

// CS0655.cs
using System;

class MyAttribute : Attribute
{
   // decimal is not valid attribute parameter type
   public decimal d = 0;
   public int e = 0;
}

[My(d = 0)]   // CS0655
// try the following line instead
// [My(e = 0)]
class C
{
   public static void Main()
   {
   }
}
