Getting a path of a running process by name
提问by hlatif
How can I get a path of a running process by name? For example, I know there is a process named "notepad" running, and I want to get the path of it. How to get the path without looping through all other processes?
如何按名称获取正在运行的进程的路径？例如，我知道有一个名为“notepad”的进程正在运行，我想获取它的路径。如何在不循环所有其他进程的情况下获得路径？
Not this way!
不是这样！
using System.Diagnostics;
foreach (Process PPath in Process.GetProcesses())
{
if (PPath.ProcessName.ToString() == "notepad")
{
string fullpath = PPath.MainModule.FileName;
Console.WriteLine(fullpath);
}
}

Try something like this method, which uses the GetProcessesByNamemethod:
尝试使用以下GetProcessesByName方法的类似方法：
public string GetProcessPath(string name)
{
Process[] processes = Process.GetProcessesByName(name);
if (processes.Length > 0)
{
return processes[0].MainModule.FileName;
}
else
{
return string.Empty;
}
}
Keep in mind though, that multiple processes can have the same name, so you still might need to do some digging. I'm just always returning the first one's path here.
但是请记住，多个进程可以具有相同的名称，因此您可能仍然需要进行一些挖掘。我总是在这里返回第一个路径。

There is a method GetProcessesByNamethat existed in .Net 2.0:
.Net 2.0 中有一个GetProcessesByName方法：
foreach (Process PPath in Process.GetProcessesByName("notepad"))
{
string fullpath = PPath.MainModule.FileName;
Console.WriteLine(fullpath);
}

There are really two approaches you can take.
您可以采取两种方法。
You can do process by name:
您可以按名称进行处理：
Process result = Process.GetProcessesByName( "Notepad.exe" ).FirstOrDefault( );
or you could do what you do but use linq
或者你可以做你所做的但使用 linq
Process element = ( from p in Process.GetProcesses()
where p.ProcessName == "Notepad.exe"
select p ).FirstOrDefault( );
