如何使用C＃中的当前活动进程获取持续时间？

Question

有没有办法知道在c＃中打开的当前窗口的窗口名称和持续时间，并在窗口关闭时获得回调？

Answer 1

using System.Diagnostics;

Process[] processlist = Process.GetProcesses();

foreach (Process process in processlist)
{
    if (!String.IsNullOrEmpty(process.MainWindowTitle))
        Console.WriteLine("Process: {0} ID: {1} Window title: {2}" duration: {3}" , process.ProcessName, process.Id, process.MainWindowTitle, process.duration);
}

// i'm not sure if process.duration actually exists but it would be something like that 

Answer 2

Yes, using the Process class you can get that information.

using System.Diagnostics;

public void GetProcessesInfo()
{
    Process[] allProcesses = Process.GetProcesses();

    foreach (Process process in allProcesses)
    {
        try
        {
            string windowName = process.MainWindowTitle;
            TimeSpan duration = DateTime.Now - process.StartTime;
            process.EnableRaisingEvents = true;
            process.Exited += new EventHandler(process_Exited);
        }
        catch(System.ComponentModel.Win32Exception)
        {
            //access to that process was denied
        }
    }
}

void process_Exited(object sender, EventArgs e)
{
    //a process has exited
}
