โปรเจ็กส์แบบ Web ใช้คำสั่ง Field แล้วได้ Error

DataRow row0 = dt.Rows[0];
DateTime createDate = row0.Field<DateTime>("createdate");

'System.Data.DataRow' does not contain a definition for 'Field' and no extension method 'Field' accepting a first argument of type 'System.Data.DataRow' could be found (are you missing a using directive or an assembly reference?)

ทางแก้ ให้ติดตั้ง System.Data.DataSetExtensions

• DataRow does not contains a defination for Fields #607

PM> Install-Package System.Data.DataSetExtensions
