Question

I m trying to select a column’s value from a datatable based on conditions.

var results = from DataRow myRow in dtCallBack.AsEnumerable()
              where myRow.Field<DateTime>(1) == startDateTime
                 && myRow.Field<int>(0) == callBackID
              select myRow.Field<int>(3);

My datatable contains 4 columns ID,Date1,Date2,IntVal

I want to convert the variable results to int. (I want to return the column 4 IntVal)
