Navigation for dotNetTips.com - Checking for Valid Numeric Value

Unfortunately to do so, it must rely on an exception to detect a invalid value which is a little bit of a performance hit.

public static bool IsNumeric(object value) 

{ 

  bool returnValue = false;

  try

    {

      double check = double.Parse(value.ToString(), NumberStyles.Any, 
	NumberFormatInfo.CurrentInfo);

      returnValue = true;

    }

  catch

    {}

  return returnValue;

}

I would think that this would also work in normal C# applications.
