第三種方法：基本思路是使用Process.Start(“iexplore.exe”, ” www.msn.com.cn”)開啟一個IE的視窗，然後再使用SetParent將該新視窗併入WPF的主視窗中。程式碼如下（其他函式宣告見附錄）：

程式碼　　　　 var process = Process.Start("iexplore.exe", " www.msn.com.cn");

            process.WaitForInputIdle();

              //讓IE準備好

            Thread.Sleep(3000);

            var
 
 ieHandle = FindWindow("ieframe", null);

            SetParent(ieHandle, this.Handle);

            int style = GetWindowLong(ieHandle, GWL_STYLE);

   SetWindowLong(ieHandle, GWL_STYLE, (style & ~WS_CAPTION));

具體的思路是：

Create a WindowsFormsHost and add it to a panel in your UI

Start the process (such as Notepad) using Process.Start

Call process.WaitForInputIdle

Use process.MainWindowHandle to get the window handle

Call SetWindowPos to set the process’s window to the coordinates and Z Order of the HwndHost window

Hook both the HwndHost and the process.MainWindowHandle to detect size changes and repeat step 5.
