怎么不用IE内核啊？那个很方便的
本人的思路是：根据句柄来获得浏览器控件
1.通过进程获取窗口的句柄
IntPtr hwnd= Process.GetCurrentProcess().MainWindowHandle;
2.使用FindWindowEx api，然后根据父窗口和类名来获取浏览器控件句柄
[DllImport(“User32.dll”, EntryPoint = “FindWindowEx”)]
private static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpClassName, string lpWindowName);
IntPtr chrome = FindWindowEx(hwnd, null, “Chrome_WidgetWin_1”,null);//可以本人查看一下具体参数
查看句柄，可以使用vs下的spy++，可以获取句柄的基本信息，包括类名和窗口标题等
3.假如知道浏览器的标题，还可以进行判断
[DllImport(“user32.dll”)]
public static extern int GetWindowTextLength(IntPtr hWnd);

[DllImport(“User32.dll”, CharSet = CharSet.Auto)]
public static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int nMaxCount);
int length = GetWindowTextLength(hWnd);
StringBuilder windowName = new StringBuilder(length + 1);
GetWindowText(hWnd, windowName, windowName.Capacity);
windowName  //窗口标题

这个类在WinfForm的示例里面有，看OnBeforePopup里面注释掉的代码。
