Cleverly use the contains () method to find whether a number is in a heap number

Problem: To determine the number of user input, or the value of a parameter of a method in a program, or whether the value of a variable is in a heap number.

Concise notation: Put the heap number in the list, using the list's contains () method to check whether the list contains this number, reverse.

The code is as follows:

 Static voidMain (string[] args) {Console.WriteLine ("Please enter a number:"); stringinput=Console.ReadLine (); if(! (Newlist<string> () {"3","Ten"," One"," A"," +"," A","Wuyi"}). Contains (input))//Contains () contains,! Take counter            {                //This heap number does not contain user input numbers, to do somethingConsole.WriteLine ("not included! ");        } console.readkey (); }
