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）

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）;

其他
{在此处输入代码
会话[userauthentication] =;
}
}
根据应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
Master Page.cs file:
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";
}
}
Login Page 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"]="";
}
}
there are different roles according to that different hyperlink should be enabled and disabled... i'm getting problem in master page while its not storing session instring role=(string)(Session["userauthentication"]); please help me with this since i'm new to asp.net
推荐答案
Hai
首先你检查会话[ userauthentication]使用一些变量，比如
Hai
First u check Session["userauthentication"] using some varible,like
String user =Session["userauthentication"] as String;
你在哪里分配会话？在登录页面？请检查你是否在登录页面获得价值itlef。如果你得到价值然后分配会话并检查这样的主页.get和cast
where u assign session ? in login page ? pls check u get value or not in login page itslef.if u get value then assign session and check in master page like this .get and cast
String str= Session["userauthentication"] as String;
