generics - Can you use "where" to require an attribute in c#?

Question

I want to make a generic class that accepts only serializable classes, can it be done with the where constraint?

The concept I'm looking for is this:

public class MyClass<T> where T : //[is serializable/has the serializable attribute]

Answer 1

Nope, I'm afraid not. The only things you can do with constraints are:

• where T : class - T must be a reference type
• where T : struct - T must be a non-nullable value type
• where T : SomeClass - T must be SomeClass or derive from it
• where T : ISomeInterface - T must be ISomeInterface or implement it
• where T : new() - T must have a public parameterless constructor

Various combinations are feasible, but not all. Nothing about attributes.
