post和get传值

 send.aspx:

 if (e.CommandName == "ChaXun")
        {
            LinkButton Lik=(LinkButton)e.Item.FindControl("LinkButton1");
            Context.Items["username"] =Lik.CommandArgument.ToString();
            Server.Transfer("Default2.aspx");
 或者直接用按钮事件：

 protected void Button1_Click(object sender, EventArgs e)
    {
        Context.Items["username"] =Lik.CommandArgument.ToString();
            Server.Transfer("Default2.aspx");
    }

recive.aspx:

string TextBox1 = Context.Items["username"].ToString();
            Response.Write(TextBox1);

get传值：
send：
<asp:LinkButton ID="LinkButton1" runat="server"  PostBackUrl='<%# "~/Default2.aspx?PKID="+Eval("ID") %>'>

receive：
string str= Request.QueryString["PKID"];
