清除webBrowser 缓存和Cookie的解决方案

转自:http://www.cnblogs.com/midcn/p/3527123.html

通过测试webBrowser与IE缓存和Cookie都存放在Local Settings\Temporary Internet Files，我们可以直接调用IE API进行清除

解决方案1：

public enum ShowCommands : int

{

SW_HIDE = 0,

SW_SHOWNORMAL = 1,

SW_NORMAL = 1,

SW_SHOWMINIMIZED = 2,

SW_SHOWMAXIMIZED = 3,

SW_MAXIMIZE = 3,

SW_SHOWNOACTIVATE = 4,

SW_SHOW = 5,

SW_MINIMIZE = 6,

SW_SHOWMINNOACTIVE = 7,

SW_SHOWNA = 8,

SW_RESTORE = 9,

SW_SHOWDEFAULT = 10,

SW_FORCEMINIMIZE = 11,

SW_MAX = 11

}

 

[DllImport("shell32.dll")]

static extern IntPtr ShellExecute( IntPtr hwnd, string lpOperation, string lpFile, string lpParameters, string lpDirectory, ShowCommands nShowCmd);

 

//清除IE临时文件

                ShellExecute(IntPtr.Zero, "open", "rundll32.exe", " InetCpl.cpl,ClearMyTracksByProcess 255", "", ShowCommands.SW_HIDE);

 

 

其中ClearMyTracksByProcess 可进行选择设置 ：

 

Temporary Internet Files  （Internet临时文件）

 

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8

 

Cookies

 

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2

 

History (历史记录)

 

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1

 

 

 Form. Data （表单数据）

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16

 

 

 Passwords (密码）

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32

 

 

 Delete All  （全部删除）

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255

 

解决方案2：快速清除webBrowser Cookie

 

for (int i = 0; i < this.webBrowser1.Document.Cookie.Count(); i++)

{
   this.webBrowser1.Document.Cookie.Remove(i);
}
