C# How to loop user input until the datatype of the input is correct?

Question

How to make this piece of code loop asking for input from the user until int.TryParse()

is successful?

//setX
    public void setX()
    {
          


        

Answer 1

Even though the question has been already marked as answered, do-while loops are much better for validating user input.

Notice your code:

Console.WriteLine("The value must be of integer type");
while (!int.TryParse(Console.ReadLine(), out temp2))
    Console.WriteLine("The value must be of integer type");

You have the same code at top and bottom. This can be changed:

do {
    Console.WriteLine("The value must be of integer type");
} while (!int.TryParse(Console.ReadLine(), out temp2));
