Why is the Process.GetProcessesByName() always null?
提问by SUT
I try to use program to check the process if it exists.
我尝试使用程序来检查进程是否存在。
using System;
using System.Diagnostics;
using System.ServiceProcess;
namespace ServProInfo
{
class Program
{
public static int IfProcessExist(string processName)
{
try
{
Process[] targetProcess = Process.GetProcessesByName(processName);
int proLen = targetProcess.Length;
if (proLen == 0)
{
Console.WriteLine("The process does NOT exist or has exited...");
return 0;
}
Console.WriteLine("The process status is: Running");
return 1;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message + "\r\n" + ex.StackTrace + "\r\n" + ex.Source);
return -1;
}
}
static void Main(string[] args)
{
string type = args[0];
string name = args[1];
switch (type)
{
case "p":
IfProcessExist(name);
break;
}
}
}
}
However, the Process[] targetProcess is alway null, even when I set processName as an exist process's name.
但是，Process[] targetProcess 始终为空，即使我将 processName 设置为现有进程的名称。
How could I correct the program?

You can try the following: (works fine for me)
您可以尝试以下操作：（对我来说很好用）
Process[] targetProcess = Process.GetProcessesByName(Path.GetFileNameWithoutExtension(processName));

try this
尝试这个
System.Diagnostics.Process[] p1 = System.Diagnostics.Process.GetProcesses();
foreach (System.Diagnostics.Process pro in p1)
{
if ((pro.ProcessName.ToUpper().Contains("Application Nanme")
{
//U r Operations
}
}
