IsNumeric

.NET is missing an IsNumeric function (for c# users anyway). It's dead simple to write one though:

private bool IsNumeric(string s)
{
    try
    {Int32.Parse(s);}
    catch
    {return false;}
    return true;
}

Don't forget Int32.TryParse()

Example usage :

  int someNumber;

  if (!Int32.TryParse(s, out someNumber))

  {

    // Not an int

  }

Another example:

int classificationID = 0;

int.TryParse("123", out classificationID);
