Use the static TryParse method of any of the numeric types.
For example, to determine whether a string contains a double, use the following method:
string str = "10.5";
double result = 0;
if (double.TryParse(str,
System.Globalization.NumberStyles.Float,
System.Globalization.NumberFormatInfo.CurrentInfo,
out result))
{
// Is a double!
}
Here is another Example:
int n;
bool isNumeric = int.TryParse("123", out n);
