Question

我正在尝试使用可以同时运行多个请求（使用Webbrowser控件）但具有不同代理设置的程序在我的服务器上运行特定测试。我现在使用的是工作，但仅适用于一个webbrowser控件，我正在寻求如何并排运行多个建议。

 <Runtime.InteropServices.DllImport("wininet.dll", SetLastError:=True)> _
Private Shared Function InternetSetOption(ByVal hInternet As IntPtr, ByVal dwOption As Integer, ByVal lpBuffer As IntPtr, ByVal lpdwBufferLength As Integer) As Boolean
End Function

Public Structure Struct_INTERNET_PROXY_INFO
    Public dwAccessType As Integer
    Public proxy As IntPtr
    Public proxyBypass As IntPtr
End Structure

Private Sub RefreshIESettings(ByVal strProxy As String)
    Const INTERNET_OPTION_PROXY As Integer = 38
    Const INTERNET_OPEN_TYPE_PROXY As Integer = 3

    Dim struct_IPI As Struct_INTERNET_PROXY_INFO

    ' Filling in structure
    struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY
    struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy)
    struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local")

    ' Allocating memory
    Dim intptrStruct As IntPtr = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI))

    ' Converting structure to IntPtr
    Marshal.StructureToPtr(struct_IPI, intptrStruct, True)

    Dim iReturn As Boolean = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, System.Runtime.InteropServices.Marshal.SizeOf(struct_IPI))
End Sub

Private Function loadpage()
    sInputLine = srFileReader.ReadLine()
    Debug.WriteLine("Starting Proxy " & sInputLine)
    RefreshIESettings(sInputLine)
    Timer1.Enabled = True
    Timer1.Interval = My.Settings.timeout * 1000
    'set label
    Label3.Text = "Attempting: " & sInputLine
    Label3.ForeColor = Color.Black
    Label3.Visible = True
    WebBrowser1.Navigate("http://www.MYSERVER.com")
    Return True
End Function

loadpage（）正在从DocumentCompleted Event中的计时器循环。

请帮忙，我已经搜索了 - 解决方案。

无法帮助您使用webbrowser控件本身，但您可以使用具有Proxy属性的HttpWebRequest手动检索远程内容。 http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.proxy.aspx

多个Webbrowser控件使用不同的代理运行
