.net小生初学多指教...

SqlConnection scn = new SqlConnection("server=.;database=NewTest;uid=sa;pwd=sa;");
scn.Open();
string str = "select * from test order by case";
SqlDataAdapter ada = new SqlDataAdapter(str, scn);
DataSet ds = new DataSet();
ada.Fill = ds; --这里错了
应该是：ada.Fill(ds);
this.GridView1.DataSource = ds;
this.GridView1.DataBind();
scn.Close();

ada.Fill = ds; 应该是这样引用吧ada.Fill(ds);

SqlConnection scn = new SqlConnection("server=.;database=NewTest;uid=sa;pwd=sa;");
scn.Open();
string str = "select * from test order by case";
SqlDataAdapter ada = new SqlDataAdapter(str, scn);
DataSet ds = new DataSet();
ada.Fill = ds; 这句错了！ds是数据集的对象，应先填充，再关联，改为ada.Fill(ds); 或者两句合一句ada.Fill （new DataSet()）也可以
this.GridView1.DataSource = ds;
this.GridView1.DataBind();
scn.Close();
