asp.net中IDataParameter調用存儲過程的實現方法

 具體實現方法如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 public string GenerateExamePaper(string paperType, string driverID, string MacAddr) {   int i;   IDataParameter[] iData = new SqlParameter[4];   iData[0] = new SqlParameter("@paperType", paperType);   iData[1] = new SqlParameter("@driverID", driverID);   iData[2] = new SqlParameter("@MacAddr", MacAddr);   iData[3] = new SqlParameter("@sReturn", SqlDbType.Char, 50, ParameterDirection.Output, false, 0, 0, string.Empty, DataRowVersion.Default,null);   string aaa = "";   i= DbHelperSQL.RunProcedureParOut("Pro_GenerateExamePaper", iData, out aaa).ToString();      return aaa; }    /// <summary> /// 執行存儲過程，返回影響的行數  /// </summary> /// <param name="storedProcName">存儲過程名</param> /// <param name="parameters">存儲過程參數</param> /// <param name="rowsAffected">影響的行數</param>    /// <param name="rowsAffected">返回output值</param>    /// <returns></returns> public static int RunProcedure(string storedProcName, IDataParameter[] parameters, out int rowsAffected,out str) {   using (SqlConnection connection = new SqlConnection(connectionString))   {  int result;  connection.Open();  SqlCommand command = BuildIntCommand(connection, storedProcName, parameters);  rowsAffected = command.ExecuteNonQuery();  result = (int)command.Parameters["ReturnValue"].Value;     str= (int)command.Parameters["@sReturn"].Value;  return result;   } }
