vb.net - 每个循环加倍

Question

这个循环有什么问题？

我注意到a字符串没有改变，但我猜它应该移动到列表中的下一个字符串，而它适用于ProxyList.

Public Class Form1

    Public ProxyList As New List(Of String)
    Public AccountList As New List(Of String)

    For Each a As String In AccountList
        Dim z() As String = a.Split(":")

        For Each p As String In ProxyList
           ' SENDS WEBREQUESTS BY USING ACCOUNTS AND SETS PROXY '
        Next
    Next

结束类

这将为proxyList中的每个项目循环一次帐户列表，如果帐户列表中有5个项目，proxyList中有10个项目，则此代码将循环50次。这段代码没有任何问题，只是它与您想要的不匹配。

根据您的评论，您希望 accountList 和 proxyList 都平等地向前推进，您应该真正定义一个新类：

Public Class ProxyAccount
    Public Proxy As String
    Public Account As String
End Class

然后你的代码变成：

Public Class Form1

    Public ProxyList As New List(Of ProxyAccount)

    For Each pa As ProxyAccount In ProxyList 
        Dim a as String = pa.Account
        Dim z() As String = a.Split(":") 
        Dim p as String = pa.Proxy   
        ' SENDS WEBREQUESTS BY USING ACCOUNTS AND SETS PROXY '
        Next
    Next
End Class

或者你也可以这样做：

Public Class Form1

    Public ProxyList As New List(Of String)
    Public AccountList As New List(Of String)

    For i as Integer = 0 To ProxyList.Count - 1  
        If i >= AccountList.Count Then   
            Exit For
        End If
        Dim a As String = AccountList(i)    
        Dim z() As String = a.Split(":")  
        Dim p as String = ProxyList(i)  
        ' SENDS WEBREQUESTS BY USING ACCOUNTS AND SETS PROXY '
    Next
End Class

这两者中的任何一个都可以正常工作，但是您需要重构代码以使其更清晰。
