获取asp.net中的id

<asp:GridView ID="gv" runat="server" DataSourceID="SqlDataSource2" >
<Columns>
<asp:HyperLinkField DataNavigateUrlFields="ID" DataNavigateUrlFormatString="News/news.aspx?newsid=" Target="_blank"
DataTextField="Title" NavigateUrl="News/news.aspx?newsid="/>
<asp:BoundField DataField="AddTime" ShowHeader="false" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:ASPConnectionString %>"
SelectCommand="SELECT top 6 [Title], [Addtime],[ID] FROM [News] order by ID desc">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="1" Name="ID" QueryStringField="ID" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>

这是news页面
int id = Convert.ToInt32(Request.QueryString["newsid"]);
//Response.Write(id);
string settings = Convert.ToString(ConfigurationManager.ConnectionStrings["ASPConnectionString"]);
System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(settings);
con.Open();
如何获取表
News中的id
是不是传newsid传错了
数据库
News
（ID，Title，Author，AddTime，Content，Neirong）

Answer 1

<asp:HyperLinkField DataNavigateUrlFields="ID" DataNavigateUrlFormatString="News/news.aspx?newsid=" Target="_blank"
DataTextField="Title" NavigateUrl="News/news.aspx?newsid="/>
这个直接换成
<a href='News/news.aspx?newsid=<%# Eval("ID")#>>' />

你根本就没传啊,<asp:HyperLinkField DataNavigateUrlFields="ID" DataNavigateUrlFormatString="News/news.aspx?newsid={0}" Target="_blank"这样才能把ID传过去
