使用C＃更改浏览器的大小(Change browser size using C#)

我可以改变从C＃中的浏览器的宽度？

我想要做类似这样：

var window = window.open("page.html");
window.resize(100,100);

但在C＃中，这样的事情：

Process p = Process.GetProcessesByName("page.html")[0];
p.resize(100,100);

可能吗？

一旦你获得了手柄的应用程序的主窗口，如浏览器，你可以使用Windows API SetWindowPos()来改变它的大小。

你会从什么地方得到一样的窗口句柄Process.MainWindowHandle或致电如某些Windows API方法FindWindow()

下面是一个例子。为了测试它，首先打开Notepad ，而无需打开一个文件，以便其标题正是"Untitled - Notepad" 。这是必要的，因此FindWindow()的示例代码会发现它。

如果您运行的代码，它应该移动和调整记事本窗口。它可能会倒闭的Visual Studio的背后，因为这将是活动窗口，所以你需要mimimise Visual Studio中看到记事本去了。

在P /从获得调用声明PInvoke.Net 。
