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 *)

While coding a server, I came across something that I didn't recognize, which is byte[][].
What does this syntax mean, and how do I get rid of the message?
It's a Jagged Array in C#. To be short, it's an Array of Arrays holding bytes.

Find and extract a number from a string

I already tried to determinate the digits in a sentence using 'isDigit', but this gives me a 'bool' output. I need an 'int' output.
What i want to do is, say, i have the sentence "cheese23"; "2" and "3" will be put in their own variable, so i can add/subtract/multiply/ etc them.
(x=2,y=3;)
help will be hugely appreciated (self-teaching beginner here)
Do:
int[] intArray = "Cheese23".Where(Char.IsDigit).Select(c => int.Parse(c.ToString())).ToArray();
This extracts the numbers in the string in the order and creates an array out of it.
Then you can do intArray[0] to get 2 and intArray[1] to get 3.
Search up LINQ to see how those chain of methods did 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.

I want to get all Enum.values as string[].
I tryed using
Array mPriorityVals = Enum.GetValues(typeof(MPriority));
But how do I cast it as string[]?
You just need Enum.GetNames method, Enum.GetValues gives the result as EnumType rather than string.
string[] names = Enum.GetNames(typeof (MPriority));
I suggest you to just use GetNames, don't call GetValues and cast it to string as suggested in comment.
