Is there a way to convert a list from List<> to Task<List<>> ? I know Task<List<>> to List<> but I don't know to other direction.
Thanks,
Have you tried Task.FromResult(list)? Where list is the variable storing reference to your Collection.
I think you want Task.FromResult(* your List<> here *)

What is the difference between List<MyClass> and MyClass[] in C#.
Thanks
MyClass[] is an array, and once set in size it can't grow.
A List<MyClass>, however, can have things constantly added to it.

I have two sting lists
List<string> list1=new List(){"1","2","3"};
List<string> list2=new List(){"1","2"};
What will be the easiest way to check if list1 contains the values in list2.
How about
list1.Except(list2).Any();
Try using
[listName].Except(SecondListName).Any();
This should work.

How to share data between forms?
(2 answers)
Closed 8 years ago.
I'm trying to use one array that I declared in one form, to plot a graph with zedgraph, in a different form.
How do I need to declare the array and where?
Short answer: Don't declare your array in the first form.
Declare it in a separate component/class/whatever instead, and let both forms access the array there. That way, the array should be independent of the forms, and both can use it.

Immutable List in C#
Is it possible to make a list immutable
You can use ReadOnlyCollection<T> instead.
List<T>.AsReadOnly() returns a readonly wrapper, so that you can't add/remove/replace elements.
To be truly immutable, the type T must be an immutable Type.
