Accepted answer
You have used int.TryParse, similarly just use double.TryParse. That's all you have to do.

Hi Raja,
Use below code snippet for your problem,
var regex = new Regex(@"^[0-9]*(?:\.[0-9]*)?$");
if (regex.IsMatch(ds.Tables[s].Rows[i][Columncountvalue + 10].ToString().Trim()))
{
//statement
}
