[英]turn off the proxy c#
這是打開代理的代碼:
Public struct Struct_INTERNET_PROXY_INFO
{
public int dwAccessType;
public IntPtr proxy;
public IntPtr proxyBypass;
};
[DllImport("wininet.dll", SetLastError = true)]
private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength);
private void RefreshIESettings(string strProxy)
{
const int INTERNET_OPTION_PROXY = 38;
const int INTERNET_OPEN_TYPE_PROXY = 3;
Struct_INTERNET_PROXY_INFO struct_IPI;
// Filling in structure
struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY;
struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy);
struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local");
// Allocating memory
IntPtr intptrStruct = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI));
// Converting structure to IntPtr
Marshal.StructureToPtr(struct_IPI, intptrStruct, true);
bool iReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal.SizeOf(struct_IPI));
}
private void SomeFunc()
{
RefreshIESettings("192.168.1.200:1010");
System.Object nullObject = 0;
string strTemp = String.Empty;
System.Object nullObjStr = strTemp;
axWebBrowser1.Navigate("http://willstay.tripod.com", ref nullObject, ref nullObjStr, ref nullObjStr, ref nullObjStr);
}
但是我該如何關閉?????? 謝謝
看來這個問題是在一段時間之前提出的,但是我只是花了最后兩個小時研究了這個問題,卻找不到答案。 最終,我偶然發現了一個晦澀難懂的網站,上面有有效的代碼。
再次嘗試上面的代碼,但不要指定實際的代理地址,而應使用":"
。
像這樣調用RefreshIESettings
: RefreshIESettings(":")
