Please help me with the issue . I have tried lot many solution and they are not working .
rd["DOB"].ToString() = "9/19/1946";
DateTime dt1 = DateTime.ParseExact(rd["DOB"].ToString(), "MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture);
You should use “M/d/yyyy” as the format string.
MM/dd/yyyy would match 09/19/1946, but not 9/19/1946
