如何使用C＃中当前的活动过程持续时间

Question

是否有一种方法可以知道当前窗口的窗口名称和C＃中打开的窗口的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

是的，使用过程类可以获取该信息。

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
}
