您好。我试图找出如何编写代码来完成我的水平。发生的事情是，在登录页面上，我必须编程以从表中获取用户名和密码，以便用户登录。那部分有效。现在我想根据用户级别登录。如果用户是Level1，则页面将重定向到该用户的欢迎页面。如果用户是Level2，则用户转到该页面。这是我的代码：

Hello. I am trying to find out how to write the code to finish my levels. What is going on is that on the Login page I have to program to get the username and password from a table in order to have the user to login. That part works. Now I want to login depending on the user levels. If the user is a Level1 then the page redirects to a Welcome page for that user. If the user is a Level2 then the user goes to that page. Here is the code I have:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; using System.Configuration; using System.Data; public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["PassConnectionString"].ConnectionString); con.Open(); string cmdStr = "select count(*) from TableSecurity where EmailAddress= '" + TextBoxEA.Text + "'"; SqlCommand Checkuser = new SqlCommand(cmdStr, con); int temp = Convert.ToInt32(Checkuser.ExecuteScalar().ToString()); if (temp == 1) { string cmdStr3 = "select Level from TableSecurity where EmailAddress= '" + TextBoxEA.Text + "'"; SqlCommand level = new SqlCommand(cmdStr3, con); SqlDataReader reader = level.ExecuteReader(); DataTable dt1 = new DataTable(); dt1.Load(reader); foreach (DataRow dr1 in dt1.Rows) { int returnedLevel = Convert.ToInt32(dr1[0].ToString()); if (returnedLevel == 1) { Response.Redirect("~/Secure.aspx"); } else if (returnedLevel == 2) { Response.Redirect("~/WelcomeIALO.aspx"); } } } con.Close(); } }

推荐答案

也许您首先需要使用本教程学习该主题：www.asp/web-forms/tutorials/security/roles/基于角色的授权-cs [ ^ ]。

Perhaps you first need to study the subject using this tutorial: www.asp/web-forms/tutorials/security/roles/role-based-authorization-cs[^].

以下是您需要添加/更改以使其正常工作的代码： Here is the code you need to add/alter in order for it to work: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; using System.Configuration; using System.Data; public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["PassConnectionString"].ConnectionString); con.Open(); string cmdStr = "select count(*) from TableSecurity where EmailAddress= ''" + TextBoxEA.Text + "''"; SqlCommand Checkuser = new SqlCommand(cmdStr, con); int temp = Convert.ToInt32(Checkuser.ExecuteScalar().ToString()); if (temp == 1) { con.Close(); string cmdStr3 = "select Level from TableSecurity where EmailAddress= ''" + TextBoxEA.Text + "''"; con.Open(); SqlCommand level = new SqlCommand(cmdStr3, con); SqlDataReader reader = level.ExecuteReader(); DataTable dt1 = new DataTable(); dt1.Load(reader); foreach(DataRow dr1 in dt1.Rows) { int returnedLevel = Convert.ToInt32(dr1[0].ToString()); if(returnedLevel == 1) { Response.Redirect("~/Secure.aspx"); } else if(returnedLevel == 2) { Response.Redirect("~/WelcomeIALO.aspx"); } } } con.Close(); }
