Question

下面这段是什么意思啊！
SqlParameter[] parameters = {   
new SqlParameter("@_DanWeiBianHao",this.TextBoxaa.Text.ToString().Trim()),
new SqlParameter("@_StartTime",DateTime.Parse(DDLNianDu1.QsNianDu)),
new SqlParameter("@_EndTime",DateTime.Parse(DDLNianDu1.JzNianDu)),
new SqlParameter("@_condition",ViewState["TiaoJian"].ToString()),
new SqlParameter("@_kind","1"),
new SqlParameter("@MyNianDu",this.DDLNianDu1.MyNianDu)
};

Answer 1

执行一条sql语句需要参数，这是在构造参数。
SqlParameter（）方法的第一个参数是参数的名称，第二个是参数的值。

Answer 2

给你个例子看下： public void AddCarConfiguration(ECUData.DataManage.CarConfiguration carConfiguration)
        {
            int insertID = 0;
            string insertSql = "insert into CarConfiguration(Name,CollateStatus,CollateComment,AuditingStatus,AuditingComment,DFID,EngineModel,VehicelModel,Idle,KTKZMS,QDJKZMS,PQZDMK,DZYMTBCJ,XHGN,PTOGN,RYYSBJGN,BSXXH,HQSB,LTGG,CSXHHQFS,FDJZSSCFS,SWSCFS,JYYLSCFS,SFDCANZX,JQJRMK,CJQDTZGN,Comment) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
            using (Gongfang.Data.OleSql oleSql = new OleSql(conn))
            {
                System.Data.OleDb.OleDbParameter[] parameters = new OleDbParameter[27];
                parameters[0] = new System.Data.OleDb.OleDbParameter("@1", carConfiguration.Name);
                parameters[1] = new System.Data.OleDb.OleDbParameter("@2", carConfiguration.CollateStatus);
                parameters[2] = new System.Data.OleDb.OleDbParameter("@3", carConfiguration.CollateComment);
                parameters[3] = new System.Data.OleDb.OleDbParameter("@4", carConfiguration.AuditingStatus);
                parameters[4] = new System.Data.OleDb.OleDbParameter("@5", carConfiguration.AuditingComment);
                parameters[5] = new System.Data.OleDb.OleDbParameter("@6", carConfiguration.DFID);

                parameters[8] = new System.Data.OleDb.OleDbParameter("@9", carConfiguration.Idle);
                parameters[9] = new System.Data.OleDb.OleDbParameter("@10", carConfiguration.KTKZMS);
                parameters[10] = new System.Data.OleDb.OleDbParameter("@11", carConfiguration.QDJKZMS);
                parameters[11] = new System.Data.OleDb.OleDbParameter("@12", carConfiguration.PQZDMK);

                parameters[16] = new System.Data.OleDb.OleDbParameter("@17", carConfiguration.BSXXH);
                parameters[17] = new System.Data.OleDb.OleDbParameter("@18", carConfiguration.HQSB);
                parameters[18] = new System.Data.OleDb.OleDbParameter("@19", carConfiguration.LTGG);
                parameters[19] = new System.Data.OleDb.OleDbParameter("@20", carConfiguration.CSXHHQFS);
                parameters[20] = new System.Data.OleDb.OleDbParameter("@21", carConfiguration.FDJZSSCFS);
                parameters[21] = new System.Data.OleDb.OleDbParameter("@22", carConfiguration.SWSCFS);

                parameters[25] = new System.Data.OleDb.OleDbParameter("@26", carConfiguration.CJQDTZGN);
                parameters[26] = new System.Data.OleDb.OleDbParameter("@27", carConfiguration.Comment);
                oleSql.Execute(insertSql, parameters)；                }
                             
        }
