Input validation with integer and int.tryparse : <p>So i nearly have 2k lines of code and i have forgotten to / i do not know how to have input valdation on user inputs such as</p>

<pre><code>cw("Hello Please Enter your age");
                cw("If you are in a Group Input the Age of the Youngest Member of the Group.");
                Age = Convert.ToInt32(Console.ReadLine());
</code></pre>

<p>I want to Make it so that users can enter only numbers and my program will not crash when they put in somthing els.</p>

<p>this is a common problem in the whole of my program for the console.readlines. </p>

<p>Is there a way on mass that i can introduce the input valdation for numbers only and letters only when approate?</p>

<p>thank you in advance. </p>
