Here is my proxy code.
[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);
}
This code works fine with a windows from app. I tried using it in a console app and checked my ip but it did not work. Here is how i used it in a console app,
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 is a class i got from : Get public/external IP address?
I want the proxy to work with the console app. I am not sure what is the problem I will also run multiple instances of program so I want each console using one proxy and it should only affect the browsing of the console and not whole computer. Proxies will have no authentication.
Here is my own HTTPBase class which handles all the http requests for the whole app,

So I want to be able to add the proxy in this code. I will pass a variable from main form which will have the proxy:port format and I want this code to use the proxy. I am new to these proxy things and having some confusions. I use net framework 4.0 in VS 12.
