c# - 使用c#在IE中打开一个页面

Question

我正在使用 c# 在 IE 中打开网页

代码：

Process.Start("IExplore.exe", "www.northwindtraders.com");

但是，如何使用以下特征调整页面大小：toolbar=no, location=no, status=no, menubar=no, scrollbars=yes, resizable=yes, width='622', height='582'

Answer 1

对于我认为无法从命令行获得的那种细粒度控制；添加对Microsoft Internet Controls的引用 (COM)即可；

var IE = new SHDocVw.InternetExplorer();
object URL = "http://www.northwindtraders.com";

IE.ToolBar = 0;
IE.StatusBar = false;
IE.MenuBar = false;
IE.Width = 622;
IE.Height = 582;
IE.Visible = true;

IE.Navigate2(ref URL);

Answer 2

这些是从命令外壳打开 Internet Explorer 的功能：http:

Answer 3

您需要使用StartInfo属性来设置一些启动参数。

检查此链接以了解可用的选项。

Answer 4

通过直接使用 COM 对象，您可以在不引用 SHDocVw 的情况下执行此操作：

const int FormWidth = 800;
const int FormHeight = 600;

您还可以使用 VirtualScreen

System.Windows.Forms.SystemInformation.VirtualScreen.Width;
System.Windows.Forms.SystemInformation.VirtualScreen.Height;

而不是 PrimaryScreen

Answer 5

另一种方法是使用从 PInvoke.net 抛出的窗口消息

void Main()
{
 Process p = Process.Start( 
    @"C:\Program Files (x86)\Internet Explorer\iexplore.exe" , "www.google.com" );

 while(p.MainWindowHandle == IntPtr.Zero )
 {
  Thread.Sleep(100);
  p.Refresh();
 }

 SetWindowPos( p.MainWindowHandle , IntPtr.Zero , 100 , 100, 800 ,400 , SetWindowPosFlags.ShowWindow ); 


}
