Cannot Implicitly Convert type 'int' to 'string' c# , sql server

trying to insert sql statement by passing in parameters,
but one of the parameters datatype does not fit,

have checked that the datatype field in sql server are matched with the parameters datatype,
string strInsertStatus = InsertStudentAttendanceNTraineeModule(Convert.ToDateTime(dtSAC.Rows[0]["arrivedtime"]), Convert.ToDateTime(dtSAC.Rows[0]["actualtime"]),
                                Convert.ToDateTime(dtSAC.Rows[0]["leavetime"]), Convert.ToDateTime(dtSAC.Rows[0]["actualleavetime"]), dtSAC.Rows[0]["attendancestatus"].ToString(),
                                dtSAC.Rows[0]["lateduration"].ToString(), dtSAC.Rows[0]["earlierduration"].ToString(), dtSAC.Rows[0]["leavestatus"].ToString(), dtSAC.Rows[0]["absensereason"].ToString(),
                                Convert.ToInt64(dtTMC.Rows[0]["pid"]), Convert.ToInt64(dtTMC.Rows[0]["ctid"]), Convert.ToInt64(dtTMC.Rows[0]["mid"]), Convert.ToInt64(dtTMC.Rows[0]["lid"]),
                                Convert.ToInt64(dtTMC.Rows[0]["tid"]), Convert.ToInt64(dtTMC.Rows[0]["trid"]), Convert.ToInt64(dtTMC.Rows[0]["sid"]), Convert.ToInt64(dtTMC.Rows[0]["pid"]));

Hi,

How does your declaration for InsertStudentAttendanceNTraineeModule look like? It sounds as you are trying to use an int instead of a string as defined in the method.
