You have a string value in your C# program and want to find out if it a numeric value.
Double.TryParse method, which returns true if the input string is a number. Here we see how you can use Double.TryParse to test number strings.

{
    double Result;
    return double.TryParse(s, out Result); 
}       
  
string value = "143";
if (IsNumeric(value))
