這是我的代理代碼。使用不同代理的多個控制檯應用程序
[Runtime.InteropServices.DllImport("wininet.dll", SetLastError = true)]
private static bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength);
public struct Struct_INTERNET_PROXY_INFO
{
public int dwAccessType;
public IntPtr proxy;
public IntPtr proxyBypass;
}
private void UseProxy(string strProxy)
{
const int INTERNET_OPTION_PROXY = 38;
const int INTERNET_OPEN_TYPE_PROXY = 3;
Struct_INTERNET_PROXY_INFO struct_IPI = default(Struct_INTERNET_PROXY_INFO);
struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY;
struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy);
struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local");
IntPtr intptrStruct = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI));
Marshal.StructureToPtr(struct_IPI, intptrStruct, true);
bool iReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, System.Runtime.InteropServices.Marshal.SizeOf(struct_IPI));
}
private void Button1_Click(System.Object sender, System.EventArgs e)
{
Label4.Text = (TextBox1.Text + ":" + TextBox2.Text);
}
此代碼可以正常使用來自應用程序的窗口。我試圖在控制檯應用程序中使用它，並檢查了我的IP但它不起作用。這是我如何把它用在一個控制檯應用程序，
static void Main()
{
Console.WriteLine("Ip before Proxy /r/n");
HTTPGet req = new HTTPGet();
req.Request("http://checkip.dyndns.org");
string[] a = req.ResponseBody.Split(':');
string a2 = a[1].Substring(1);
string[] a3 = a2.Split('<');
string a4 = a3[0];
Console.WriteLine(a4);
UseProxy("219.93.183.106:8080");
Console.WriteLine("Ip after Proxy /r/n");
HTTPGet req1 = new HTTPGet();
req1.Request("http://checkip.dyndns.org");
string[] a1 = req1.ResponseBody.Split(':');
string a21 = a1[1].Substring(1);
string[] a31 = a21.Split('<');
string a41 = a31[0];
Console.WriteLine(a41);
Console.ReadLine();
}
HTTPGET是一類，我從有：Get public/external IP address?
我希望代理與控制檯應用程序工作。我不知道是什麼問題 我也將運行多個程序實例，所以我希望每個控制檯使用一個代理，它應該隻影響控制檯的瀏覽而不是整個計算機。 代理將沒有身份驗證。
這是我自己的HTTPBase類處理所有整個應用程序的http請求，

所以我希望能夠添加代理在此代碼。我將從主窗體傳遞一個變量，它將使用代理：端口格式，並且我希望此代碼使用代理。我對這些代理事物很陌生，並且有些混亂。 我使用.NET框架4.0 VS 12
只有一個問題：爲什麼不使用[WebRequest.DefaultWebProxy] （http://msdn.microsoft.com/en-us/library/system.net.webrequest.defaultwebproxy.aspx）'WebRequest.DefaultWebProxy = new WebProxy（「219.93.183.106」，8080）;'？ –
