如何在C#中获取活动进程名称？

using System.Diagnostics;

public static void Main()
{
    // 获取当前进程
    Process currentProcess = Process.GetCurrentProcess();
    Console.WriteLine("当前进程名称：" + currentProcess.ProcessName);

    // 获取所有进程
    Process[] allProcesses = Process.GetProcesses();
    Console.WriteLine("所有进程名称：");
    foreach (Process process in allProcesses)
    {
        Console.WriteLine(process.ProcessName);
    }
}
