您需要使用

TextBox

控件的

Text

属性来获取值

替换此项：

    Session["FirstName"] = txtfName;
    Session["SecondName"] = txtlName;

为此：

    Session["FirstName"] = txtfName.Text;
    Session["SecondName"] = txtlName.Text;

完整代码：

protected void btnSubmit_Click(object sender, EventArgs e)
{
    Session["FirstName"] = txtfName.Text;
    Session["SecondName"] = txtlName.Text;
    Response.Redirect("WebForm2.aspx");
}

    Session["FirstName"] = txtfName.Text;
    Session["SecondName"] = txtlName.Text;

protected void btnSubmit_Click(object sender, EventArgs e)
{
    Session["FirstName"] = txtfName.Text;
    Session["SecondName"] = txtlName.Text;
    Response.Redirect("WebForm2.aspx");
}
