根據執行的查詢，登錄控制重定向到不同的頁面

Question

我有兩個查詢..我想要做的是如果登錄控件在第一個查詢表中找到用戶名和密碼，將其重定向到賣家頁面。如果它發現第二個查詢表中的un和pw然後將其重定向到經銷商頁面。我怎樣才能做到這一點？因爲它只檢查第一個查詢。

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) 
    { 
     var conString = ConfigurationManager.ConnectionStrings["CONSTRING"].ConnectionString; 
     SqlConnection con = new SqlConnection(conString); 
     string user = Login1.UserName; 
     string pass = Login1.Password; 
     con.Open(); 
     SqlCommand cmd1 = new SqlCommand("select username, password, status from login where username = '" + user + "' and password = '" + pass + "' and status = 1", con); 
     string CurrentName; 
     CurrentName = (string)cmd1.ExecuteScalar(); 
     if (CurrentName != null) 
     { 

      Session.Timeout = 1; 
      Session["un"] = Login1.UserName; 
      Response.Redirect("sellerlogin.aspx?un=" + Login1.UserName); 

     } 
     SqlCommand cmd2 = new SqlCommand("select username, password, status from dealer where username = '" + user + "' and password = '" + pass + "' ", con); 

     string CurrentNam; 
     CurrentNam = (string)cmd2.ExecuteScalar(); 
     if (CurrentNam != null) 
     { 
      Session.Timeout = 1; 
      Response.Redirect("dealerlogin.aspx?un="+ Login1.UserName); 
     }

嘗試使用：

Response.End(); 
return; 

與您的代碼：

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) 
{ 
    var conString = ConfigurationManager.ConnectionStrings["CONSTRING"].ConnectionString; 
    SqlConnection con = new SqlConnection(conString); 
    string user = Login1.UserName; 
    string pass = Login1.Password; 
    con.Open(); 
    SqlCommand cmd1 = new SqlCommand("select username, password, status from login where username = '" + user + "' and password = '" + pass + "' and status = 1", con); 
    string CurrentName; 
    CurrentName = (string)cmd1.ExecuteScalar(); 
    if (CurrentName != null) 
    { 

     Session.Timeout = 1; 
     Session["un"] = Login1.UserName; 
     Response.Redirect("sellerlogin.aspx?un=" + Login1.UserName); 
     Response.End(); 
     return; 
    } 
    SqlCommand cmd2 = new SqlCommand("select username, password, status from dealer where username = '" + user + "' and password = '" + pass + "' ", con); 

    string CurrentNam; 
    CurrentNam = (string)cmd2.ExecuteScalar(); 
    if (CurrentNam != null) 
    { 
     Session.Timeout = 1; 
     Response.Redirect("dealerlogin.aspx?un="+ Login1.UserName); 
     Response.End(); 
     return; 
    }
