        {
            IUrlHistoryStg2 vUrlHistoryStg2 = (IUrlHistoryStg2)new UrlHistory();
            vUrlHistoryStg2.ClearHistory();//清除历史
        }

Answer 3

其实这个效果很简单啊，为什么这么麻烦呢？循环
清楚COOKIE   打开WEB

我记得有COM接口可以直接调用删除IE临时文件夹的对话框，但一时找不到，只能模拟了[DllImport("User32.dll")]
        private static extern int FindWindow(string strClassName, string strWindowName);
        [DllImport("User32.dll")]
        private static extern int FindWindowEx(int hwndParent, int hwndChildAfter, string strClassName, string strWindowName);
        [DllImport("User32.dll ")]
        private static extern IntPtr PostMessage(int hwnd, int wMsg, int wParam, string lParam); 
        private const int WM_CLICK = 0x00F5;           private void button1_Click(object sender, EventArgs e)
        {
            System.Diagnostics.Process.Start("InetCpl.cpl");
            System.Threading.Thread.Sleep(300);
            int h1 = 0, h2 = 0, h3=0,h4=0,h5=0;
            h1 = FindWindow(null, "Internet 属性"); 
            if (h1 != 0)
            {
                h2 = FindWindowEx(h1, 0, null, "常规");
                if (h2 != 0)
                {
                    h3 = FindWindowEx(h2, 0, "Button", "删除文件(&F)..."); 
                    if (h3 != 0)
                    {
                        PostMessage(h3, WM_CLICK, 0, null);
                        System.Threading.Thread.Sleep(100);
                        h4 = FindWindow(null, "删除文件");
                        System.Threading.Thread.Sleep(300);
                        if (h4 != 0)
                        {
                            h5 = FindWindowEx(h4, 0, null, "确定");
                            if (h5 != 0)
                            {
                                PostMessage(h5, WM_CLICK, 0, null);
                            }
                        }
                    }
                }
