See: Process.GetProcessesByName Method (System.Diagnostics) | Microsoft Docs[^]
In the an array of returned Process components you can get the .Id property, see: Process Class (System.Diagnostics) | Microsoft Docs[^]

If you don't know the right name, try:
using System.Diagnostics;
...
Process[] processlist = Process.GetProcesses();

foreach (Process p in processlist)
{
    Console.WriteLine("Process: {0} ID: {1}", p.ProcessName, p.Id);
}

He has been trying to help you but he, nor I, am not going to write the code for you.

You're not understanding that you're getting an array of Process objects back from GetProcesses.

The problem you have is not with retrieving the processes. It's that you apparently don't know how to work with arrays.
There's several things wrong with this. First, you should be iterating over the pid2 variable not over processlist

Second of all, you're trying to write pid2 to the console, but this is an enumerable set. You need to print out information on the process itself (look at the Process[^] page in the documentation).

C#
foreach (Process process in pid2)
{
  Console.WriteLine("Process: {0} ID: {1}", process.ProcessName, process.Id);
  Console.ReadLine();
}

Remember, you can rely on intellisense in Visual Studio to help you out. And remember, if you're getting results that you're not expecting, use the debugger to step through your code and work out what's wrong.

As RickZeeland explained below, you can use the Id property of a Process object to retrieve the pid.

like this i doesn't work
var Pr = process.Id(Process.GetProcessesByName("taskmgr"));
i nee to retireve a pid from a process name you get it can you explain form please
i'm new to c#
like that

var ProcessID = from Processes in processlist where process.ProcessName=("mgr") select Processes;

It doesn't work because you're assuming that GetProcessesByName is returning a single Process object. It's not. It will always return an array of Process objects. You're trying to get the PID from the array, not from the Process objects in the array.
