named parameter type constraints

Question

I am designing a custom attribute class.

public class MyAttr: Attribute
{
    public ValueRange ValRange { get; set; }
}

Then I am attempti

Answer 1

Attribute parameters must be values of the following types (quoting the article):

• Simple types (bool, byte, char, short, int, long, float, and double)
• string
• System.Type
• enums
• object (The argument to an attribute parameter of type object must be a constant value of one of the above types.)
• One-dimensional arrays of any of the above types

Edit: Changed "compile-time constant" to "value", since types and arrays are not constants (thanks to the commenter who pointed this out (and subsequently deleted his comment for some reason...))
