Identify if a string is a number

Question

If I have these strings:

1. \"abc\" = false

2. \"123\" = true

3. \"ab2\"

Answer 1

Pull in a reference to Visual Basic in your project and use its Information.IsNumeric method such as shown below and be able to capture floats as well as integers unlike the answer above which only catches ints.

    // Using Microsoft.VisualBasic;

    var txt = "ABCDEFG";

    if (Information.IsNumeric(txt))
        Console.WriteLine ("Numeric");

IsNumeric("12.3"); // true
IsNumeric("1"); // true
IsNumeric("abc"); // false
