实在不知道哪里出错了 还望大手给我看看

  sql = "update news set columnID=@columnID, title=@title,content=@content,description=@description,display=@display,Home=@Home,Recommand=@Recommand,ImageURL=@ImageURL,MainImage=@MainImage,addDate=@addDate,RuZhiDate=@RuZhiDate,FaBuDate=@FaBuDate,Remark1=@Remark1,Remark2=@Remark2,Remark3=@Remark3,Remark4=@Remark4,Remark6=@Remark6,Remark5=@Remark5,Remark7=@Remark7 where ID=@ID";

这是一条sql语句 接着我用SqlParameter全部赋值 但是运行时总报错（必须声明标量变量@Remark6）

 arrop[0] = new SqlParameter("@columnID", Convert.ToInt32(strddlist1));
            arrop[1] = new SqlParameter("@title", strtitleName);
            arrop[2] = new SqlParameter("@content", strcontent);
            arrop[3] = new SqlParameter("@description", strdesc);
            arrop[4] = new SqlParameter("@display", strdisplay);
            arrop[5] = new SqlParameter("@Home", strHome);
            arrop[6] = new SqlParameter("@Recommand", strRecommand);
            arrop[7] = new SqlParameter("@ImageURL", newName);
            arrop[8] = new SqlParameter("@MainImage", newName1);
            arrop[9] = new SqlParameter("@addDate", Convert.ToDateTime(strAddDate));
            arrop[10] = new SqlParameter("@RuZhiDate",Convert.ToDateTime(datePX.Text));
            arrop[11] = new SqlParameter("@Remark1", newName2);
            arrop[12] = new SqlParameter("@Remark2", remark2);
            arrop[13] = new SqlParameter("@Remark3", newName3);
            arrop[14] = new SqlParameter("@Remark4", newName4);
            arrop[15] = new SqlParameter("@FaBuDate", DateTime.Now);
            arrop[16] = new SqlParameter("@Remark6", newName6);//没有声明Remark6
            arrop[17] = new SqlParameter("@Remark5", Remark5.Text);
            arrop[18] = new SqlParameter("@Remark7", newName7);

先定位具体的错误语句，应该不是new SqlParameter("@Remark6", newName6)这里出错吧。
估计你调用ExecuteNoneQuery()的时候参数不对。
还有变量newName6有值不？

运行断点进去看下呢。

把报错信息打印出来看看，这样才能具体知道哪个字段出了问题
