asp.net OleDbParameter跟顺序有关？

           OleDbParameter[] paras = new OleDbParameter[] {
           new OleDbParameter ("@title",news.Title ),
           new OleDbParameter ("@content",news.Content ),
           new OleDbParameter ("@id",news.Id )
           };
           sqlstr = "update news set title=@title,content=@content where id=@id";

 

这货居然跟顺序有关？
