Why is it impossible to declare extension methods in a generic static class?
- by Hun1Ahpu
I'd like to create a lot of extension methods for some generic class, e.g. for
public class SimpleLinkedList<T> where T:IComparable
And I've started creating methods like this:
public static class LinkedListExtensions
{
public static T[] ToArray<T>(this SimpleLinkedList<T> simpleLinkedList) where T:IComparable
{
//// code
}
}
But when I tried to make LinkedListExtensions class generic like this:
public static class LinkedListExtensions<T> where T:IComparable
{
public static T[] ToArray(this SimpleLinkedList<T> simpleLinkedList)
{
////code
}
}
I get "Extension methods can only be declared in non-generic, non-nested static class".
And I'm trying to guess where this restriction came from and have no ideas.
