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

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);}
