Question

i’m trying to do the following extension method -> converting an int to a enum, when you provide the enum :-

public static T ToEnum<T>(this int value) {     return (T)Enum.ToObject(typeof(T), value); } 

Now, i was hoping to make it so that you can only define the type T to be an enumeration. Is there any what i can restrict it?

eg.

int day = 3; DaysOfWeek dow = day<DaysOfWeek>(); // No compiler error. DaysOfWeek dow2 = day<Foo>(); // Compiler error. 

Answer 1

Use Where T: struct
