[英]How to get PID of started App in C#
I have got a few pairs of the identical apps. 我有几对相同的应用程序。
It looks like 看起来像
Pair 1: App A + App B
配对1:App A + App B
Pair 2: App A + App B
配对2:App A + App B
and etc
等等
Each App A starts App B from its folder. 每个应用程序A都从其文件夹启动应用程序B。 (They are both at the same folder.)
(它们都在同一文件夹中。)
So I start it like this 所以我这样开始
Code of App A 应用程式A的程式码
Process p = new Process();
p.StartInfo.FileName = FileManager.AppDirectoryName + "\\" + AppB;
p.Start();
And I also stop App B like this. 而且我也这样停止了AppB。
foreach (Process p in Process.GetProcesses())
{
if (p.ProcessName == AppB)
{
p.Kill();
return;
}
}
The problem is that at the same time could be many App B executing so this method does not allow to detect target App B to kill. 问题在于,同时可能有许多App B正在执行,因此此方法不允许检测到目标App B被杀死。
I assume to use PID of App B to kill it. 我假设使用App B的PID杀死它。 But I don't know how to obtain PID at the moment to start App B...
但是我不知道如何在启动App B时获取PID ...
Any clue? 有什么线索吗?
启动应用程序后,Process对象上的Id属性将指示新启动的进程的PID
var PID = p.Id;
Save a reference to the Process object: 保存对Process对象的引用:
Process p = new Process();
p.StartInfo.FileName = @"c:\windows\notepad.exe";
p.Start();
// ...
p.Kill();
or remember its PID: 或记住其PID:
Process p = new Process();
p.StartInfo.FileName = @"c:\windows\notepad.exe";
p.Start();
long pid = p.Id;
// ...
Process.GetProcessById(pid).Kill();
