Is a Specific Process Running in C#?

How to determine the running status of a process

When dealing with processes in C#, it is crucial to determine whether a specific process is running. The System.Diagnostics.Process class provides methods to determine this status.

One way is to retrieve a list of processes matching a specified name:

<code class="language-csharp">Process[] pname = Process.GetProcessesByName("notepad");
if (pname.Length == 0)
  MessageBox.Show("进程未运行");
else
  MessageBox.Show("进程正在运行");</code>

Alternatively, you can loop through all running processes to get their process IDs:

<code class="language-csharp">Process[] processlist = Process.GetProcesses();
foreach(Process theprocess in processlist){
   Console.WriteLine("进程名称: {0}，ID: {1}", theprocess.ProcessName, theprocess.Id);
}</code>

By leveraging these methods, you can effectively determine whether a specified process is running.
