IsNumeric function for c#

In VB.Net there is a useful function to check numeric data which is not available in C#. Here I m showing the IsNumeric function  for c# which can be used to achieve the same result.

bool IsNumeric(string strValue)
        {

            try
            {

                double doub = double.Parse(strValue);

                return true;
            }
            catch
            {

                return false;

            }
        }
