的BoundField

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

SqlCommand cmdReadComment = new SqlCommand("SELECT  [userName],[movieComment] FROM [movieCommentTable] WHERE [movieTitle]='" + lblHeadTitle.Text + "'", conn);

SqlDataReader dtrReadComment;

BoundField userNameBF = new BoundField();
userNameBF.DataField = "userName";
userNameBF.ItemStyle.Width = 180;
GridView2.Columns.Add(userNameBF);        

GridView2.DataBind();

Answer 1

试试这个GridView2.AutoGenerateColumns = false;。 Read more on MSDN

这样您就可以告诉GridView不要自己生成列。

另一种解决方案是，将您的查询更改为

SELECT  [userName] FROM [movieCommentTable] WHERE...

并注明BoundField的自定义代码。

希望这适合你
