得到一个进程的PID在C＃创建 [英] Getting a pid of a process created in C#

问题描述

让我们说，我想创建一个包含以下代码的新工艺：

Lets say that I'm trying to create a new process with the following code:

System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
p.StartInfo.FileName = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\AwesomeFile.exe";
p.StartInfo.Arguments = "parameter1 parameter2";
p.StartInfo.CreateNoWindow = true;
p.Start();

和正确的下一行，我会试图获取过程的PID具有以下行：

and right in the next line, I'll try to get a pid of that process with the following line:

MessageBox.Show(p.Id);

这行是给我的无过程是与此对象关联。错误。任何想法，为什么会出现这个问题？

This line is giving me the "No process is associated with this object." error. Any idea as to why this error occurs?

推荐答案

做到这一点
System.Diagnostics.Process.GetProcessesByName（processname ）[0] .ID。

Do this System.Diagnostics.Process.GetProcessesByName("processname")[0].Id.
