推荐答案

您需要在BAL项目中创建一个功能.函数将根据插入的数据返回true/false.

因此，您的下一个if语句在其中需要该功能.那对你有用.

然后您的BAL函数将调用DAL函数以在数据库中搜索单个用户名和密码.如果存在，则它将返回true.

希望这些信息对您有帮助，

谢谢

Hi,

you need to create one function in your BAL project. the function would return true/false depending upon your data that you insert.

So, your next if statement required that function in it. That will work for you.

and your BAL function will call DAL function for searching single username and password in database. if it is there then it will return true.

hope this information will helps you,

thanks

protected void imgbtnLogin_Click(object sender, ImageClickEventArgs e) 
{ 
LoginPL loginPL = new LoginPL(); 
loginPL.UserName = txtUserName.Text;
 loginPL.Password = txtPassword.Text; 
LoginBLL loginBLL = new LoginBLL();
 bool loginSuccess; loginSuccess = loginBLL.Login(loginPL);
if(loginPL.UserName == "admin" && loginPL.Password == "admin")
 { Response.Redirect("Admin/HomeUser.aspx"); 
} 
else if(loginSuccess) 
{ 
Response.Redirect("Tester/TesterWorkStatus.aspx");
 }

在从文本框中检查登录名和密码之前，将sql表中的数据获取到datatable中，如图所示下面

before checking the login name and password from the textbox, get the data from the sql table into datatable as shown below

using (SqlCommand command = new SqlCommand("SELECT UserName, Password FROM TableName WHERE UserName = '" + txtUserName.Text + "' AND Password = '" + txtPassword.Text + "'", connection))
        {
        //
        // Invoke ExecuteReader method.
        //
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                if(reader.GetString(1) == txtUserName.Text && reader.GetString(2) == txtPassword.Text)
                {
                    Response.Redirect("Admin/HomeUser.aspx"); 
                }else
                {
                    //Invalid User
                    Response.Redirect("Tester/TesterWorkStatus.aspx");
                }
            }
        }

希望这会给您一个想法...
