   how to store the datarow values into the variables using c#

 

My code as follows;
 
DataRow objRow;
objRow = objDt.NewRow();
 
objRow[0] = sCourse;
objRow[1] = sRate;
objRow[2] = ViewState["batchid"].ToString();
if (ViewState["temp"] == "P")
{
objRow[3] = ViewState["PackageID"];
}
else
{
objRow[3] = "";
objRow[4] = Convert.ToDateTime(ViewState["StDt"].ToString()); 
objRow[5] = Convert.ToDateTime(ViewState["EdDt"].ToString()); 
}
