vb.net - How do I ensure entered data is numerical?

Hello,

How could I ensure that the data entered in the following code is numerical?

        Console.Write(CurrentPlayer & " enter x coordinate: ")
        XCoordinate = Console.ReadLine()
        Console.Write(CurrentPlayer & " enter y coordinate: ")
        YCoordinate = Console.ReadLine()
        Console.WriteLine()

Code (markup):

Many Thanks,

Anhalo.

 

if IsNumeric(something) then
// do something
End If

Code (markup):

I don't have VB.NET installed at the moment. But that'll work.

 

Thanks, I'll have to try that

 

IsNumeric function will work. See also How to: Create a Numeric Text Box

 

Generally you will want to use the TryParse method - so if its an interger, you would do:

Dim testStr as string = "34"
Dim val as Integer

if (Integer.TryParse(testStr, val)) then
' we have a valid val casted as an int ready to go
end if
