Master Page.cs文件：

protected void Page_Load(object sender, EventArgs e)
    {
        string role=(string)(Session["userauthentication"]);
        if (Session["userauthentication"] != null)
        {
            HyperLink3.NavigateUrl = "E_scan_request_IP.aspx";
            HyperLink9.NavigateUrl = "scheuler_innovation.aspx";
        }
        else if (Session["userauthentication"] != null)
        {
            HyperLink3.NavigateUrl = "E_scan_request_IP.aspx";

        }
        else if (Session["userauthentication"] != null)
        {
            HyperLink9.NavigateUrl = "scheuler_innovation.aspx";
        }

    }

登录页面cs：

protected void Button1_Click(object sender, EventArgs e)
    {
        string role = DropDownList1.Text;
        string username = TextBox1.Text;
        string password = TextBox2.Text;
        con.Close();
        con.Open();
        cmd = new SqlCommand("select * from schedule_login where Role='" + DropDownList1.Text + "' and Username='" + TextBox1.Text + "' and Password='" +TextBox2.Text + "'",con);
        rd = cmd.ExecuteReader();
        if (rd.Read())
        {
            Session["userauthentication"] = role;
            Session.Timeout = 1;
            Response.Redirect("Home.aspx");
        }
        else
        {enter code here
            Session["userauthentication"]="";
        }

    }

根据应该启用和禁用不同的超链接，有不同的角色... 我在主页面遇到问题而它没有存储会话instring role =（string）（Session [“userauthentication”]）; 请帮助我，因为我是asp.net的新手

Answer 1

可能是由于这个

 string role = DropDownList1.Text;

将其更改为

string role = DropDownList1.SelectedItem.Text;

Answer 2

MasterPage中的PageLoad正在执行Button1_Click事件之前执行，这就是为什么母版页不符合Session [“userauthentication”]的新值的原因。您可以通过再次单击Button1_Click来验证这一点。

您需要在MasterPage.cs中创建一个公共方法，如SetRole（），并在Button1_Click（）中的Login.aspx.cs中调用此函数

您可以从子页面访问此主页面的SetRole（）方法：

SiteMaster.Master pageMaster = this.MasterPage as MainMaster;

if(pageMaster != null)
{
    pageMaster.SetRole();
}

在Button1_Click（）中写下此内容。希望这会有所帮助。

根据用户角色，应启用和禁用母版页超链接
