问题描述

Imports System.IO
Public Class loginscreen
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim objstreamreader As StreamReader
        Dim strline As String


        objstreamreader = New StreamReader("C:\Users\josh\Documents\computing project/user.txt.txt")

   
        strline = objstreamreader.ReadLine()

     
        Do While Not strline Is Nothing

            
            If String.Equals(strline, TextBox1.text) And
               String.Equals(strline, TextBox2.text) Then
          
                strline = objstreamreader.ReadLine


                MsgBox("correct")

                Exit Do


            Else
                
                MsgBox("incorrect login details")
                End If
        Loop
        
        objstreamreader.Close()

    End Sub
End Class

我正在使用2个文本框进行登录，需要读取文件.这条路绝对是我保存它的方式是正确的.但是，每当我运行代码时，我得到的都是msgbox错误的登录详细信息.我该如何解决?我也认为我的txt文件可以格式化

I'm making a login using 2 textboxes and need to read a file. the pathway is definitely correct its the way I saved it. however whenever I run the code all I get is the msgbox incorrect login details. how do I fix this? also I think my txt file could be formatted incorrectly how do I need my txt file to be set up?

推荐答案

我不知道，正斜杠对我来说似乎不正确" C:\ Users \ josh \ Documents \ computing project / user.txt.txt".另外，您使用文件扩展名 两次，文件名为"user.txt.txt"；可能应该是"user.txt"代替.

I don't know, the forward slash looks fishy to me "C:\Users\josh\Documents\computing project/user.txt.txt". Plus you use the file extension twice with the file name "user.txt.txt" which maybe should be "user.txt" instead.

此外，这基本上是
