Answer 1

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

}
