C# Method Attribute cannot contain a Lambda Expression?

Question

IntelliSense is telling me \"Expression cannot contain anonymous methods or lambda expressions.\" Really? I was not aware of this imposed limitation. Is this correct? I gues

Answer 1

Yes this is correct. Attribute values are limited to constants of the following types

• 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
