asp.net - 为什么用户登录名和密码不会在 Visual Studio 中加载下一页？

Question

在我制作的一个简单网站上，我的用户登录和密码屏幕出现问题。它应该会导致一个在网格视图中显示 SQL 源的新页面，但是当我按下已部署网站中的提交按钮时没有任何反应。下面是我的代码，以及我的 default.aspx 和我的 userAdmin.aspx 的源代码。代码隐藏有问题吗？如果可以，请告诉我。谢谢！

   Protected Sub butSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles butSubmit.Click

    Dim myReader As Data.SqlClient.SqlDataReader

    Dim mySqlConnection As Data.SqlClient.SqlConnection

    Dim mySqlCommand As Data.SqlClient.SqlCommand


    'Establish the SqlConnection by using the configuration manager to get the connection string in our web.config file.

    mySqlConnection = New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ToString())

    Dim sql As String = "SELECT password FROM MyUsers WHERE username = '" & Me.TextBox1.Text & "'"

    mySqlCommand = New Data.SqlClient.SqlCommand(sql, mySqlConnection)



    Try

        mySqlConnection.Open()

        myReader = mySqlCommand.ExecuteReader()


        If (myReader.HasRows) Then

            myReader.Read()

            Dim password As String = myReader("password")

            If (password = Me.TextBox2.Text) Then

                'Open page with users and roles

                Dim message As String = "Correct password"

                Dim style As MsgBoxStyle = MsgBoxStyle.OkOnly

                Dim title As String = "Authenticated"

                MsgBox(message, style, title)


            End If

        End If

    Catch ex As Exception

        Console.WriteLine(ex.ToString())

    Finally

        If Not (myReader Is Nothing) Then

            myReader.Close()

        End If

        If (mySqlConnection.State = Data.ConnectionState.Open) Then

            mySqlConnection.Close()

        End If

    End Try

End Sub

结束类

匹配密码后，您应该将浏览器重定向到新页面。

使用 Response.Redirect(newpage)
