Answer 1

You're calling Check as if it was static method. It is instance method so it should called p1.Check().

Answer 2

Compiler Error CS0120: An object reference is required for the nonstatic field, method, or property 'member'

So In order to use a non-static field, method, or property, you must first create an object instance of a class

You need to call it with the help of Task class object

p1.Check();

If you declared Check() method as static then you can call it as you are currently doing.

 public static void Check()
 {
    if (UserVer == Key)
        Console.WriteLine("Good");            
 }
