近期需要对webbrower设置代理&＃xff0c;找到了如下方案&＃xff1a;
1.
对修改注册表&＃xff0c;设置全局代理
这种方法限制在一个进程内只能设置或取消代理&＃xff0c;而且是全局代理&＃xff0c;对于部分不需要代理对功能会产生影响
2.
通过函数InternetSetOption实现修改当前程序中的WebBrowser设置
1 static class WebBrowserProxy
2
3 {
4
5 struct Struct_INTERNET_PROXY_INFO
6
7 {
8
9 public int dwAccessType;
10
11 public IntPtr proxy;
12
13 public IntPtr proxyBypass;
14
15 };
16
17
18
19 [DllImport("wininet.dll", SetLastError &＃61; true)]
20
21 static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer,int lpdwBufferLength);
22
23
24
25 public static void SetProxy(string strProxy &＃61; "127.0.0.1:8888")
26
27 {
28
29 const int INTERNET_OPTION_PROXY &＃61; 38;
30
31 const int INTERNET_OPEN_TYPE_PROXY &＃61; 3;
32
33
34
35 Struct_INTERNET_PROXY_INFO struct_IPI;
36
37
38
39 // Filling in structure
40
41 struct_IPI.dwAccessType &＃61; INTERNET_OPEN_TYPE_PROXY;
42
43 struct_IPI.proxy &＃61; Marshal.StringToHGlobalAnsi(strProxy);
44
45 struct_IPI.proxyBypass &＃61; Marshal.StringToHGlobalAnsi("local");
46
47
48
49 // Allocating memory
50
51 IntPtr intptrStruct &＃61; Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI));
52
53
54
55 // Converting structure to IntPtr
56
57 Marshal.StructureToPtr(struct_IPI, intptrStruct, true);
58
59 bool iReturn &＃61; InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal.SizeOf(struct_IPI));
60
61 }
62
63 }
