C# Process.Start "chrome.exe"/声明高度

Question

嗨，我正在尝试使用

process start 'chrome.exe'

它正在工作:

private void btnSTBAutoLogin_Click(object sender, EventArgs e)
{
        try
        {
            System.Diagnostics.Process.Start("CHROME.EXE", "https://www.google.com/chrome/browser/desktop/index.html");
        }
        catch
        {
            System.Diagnostics.Process.Start("IEXPLORE.EXE", "https://www.google.com/chrome/browser/desktop/index.html");
        }
}

问题:

我想在单击 btnSTBAutoLogin 时调整 chrome 页面的大小。

我可以调整 Chrome 页面的大小吗？ 例如:

• 高度:1280
• 宽度:800

您可以使用MoveWindow - 更改窗口大小和 GetWindowRect - 获取窗口的当前位置。

首先添加此命名空间:

 using System.Diagnostics;
 using System.Runtime.InteropServices;

下一步 - 添加 P/Invoke 代码:

[DllImport("user32.dll", SetLastError = true)]
internal static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetWindowRect(IntPtr hWnd, ref Rect lpRect);
[StructLayout(LayoutKind.Sequential)]
private struct Rect
{
   public int Left;
   public int Top;
   public int Right;
   public int Bottom;
}

最后，在 Process.Start 之后，您可以使用此过程来更改 chrome 窗口大小:

public void SetChromeSize(int width, int height)
{
   var procsChrome = Process.GetProcessesByName("chrome");   // there are always many chrome processes, so we have to find the process with a WindowHandle
   foreach (var chrome in procsChrome)
   {
      if (chrome.MainWindowHandle == IntPtr.Zero)    // the chrome process must have a window
         continue;

      var rct = new Rect();
      GetWindowRect(chrome.MainWindowHandle, ref rct);            // find and use current position of chrome window

      MoveWindow(chrome.MainWindowHandle, rct.Left, rct.Top, width, height, true);        //use MoveWindow to change size and save current position
      break;
   }
}
