C# - IsNumeric 11/22/2010
 
Finding out if keyed in text is numeric:



//works only for whole numbers
int intDummy;
if (Int32.TryParse(string, out intDummy) {
 //text is numeric
} else {
 //text is not numeric
}


//this one works for decimals

 try { 
                Decimal cValue = Convert.ToDecimal(stringText);
               //bla bla bla...
            } catch (Exception exc) {
                errorText = "invalid non-numeric value. ";
            }
