如何在c#代码中关闭Microsoft Edge browser的新选项卡

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        // 启动Microsoft Edge浏览器
        Process.Start("msedge");

        // 获取所有正在运行的Microsoft Edge进程
        Process[] edgeProcesses = Process.GetProcessesByName("msedge");

        // 关闭所有新选项卡
        foreach (Process process in edgeProcesses)
        {
            IntPtr mainWindowHandle = process.MainWindowHandle;
            ProcessThreadCollection threads = process.Threads;

            // 遍历所有线程，关闭新选项卡
            foreach (ProcessThread thread in threads)
            {
                IntPtr threadWindowHandle = thread.MainWindowHandle;

                // 关闭新选项卡
                NativeMethods.PostMessage(threadWindowHandle, NativeMethods.WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
            }
        }
    }
}

// NativeMethods类用于导入Windows API函数
class NativeMethods
{
    public const int WM_CLOSE = 0x0010;

    [System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    public static extern IntPtr PostMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);
}
