我应该将什么样的SafeHandle实现用于进程句柄？

using System;
using System.ComponentModel;
using System.Runtime.InteropServices;

class Program
{
    [DllImport("kernel32.dll", SetLastError = true)]
    static extern SafeProcessHandle OpenProcess(uint dwDesiredAccess, bool bInheritHandle, uint dwProcessId);

    static void Main(string[] args)
    {
        uint processId = 1234; // 替换为您要打开的进程的进程ID
        SafeProcessHandle processHandle = OpenProcess(0x001F0FFF, false, processId);

        if (processHandle.IsInvalid)
        {
            throw new Win32Exception();
        }

        // 在这里使用进程句柄进行操作

        // 当您不再需要进程句柄时，请将其设置为null，以便自动释放句柄
        processHandle = null;
    }
}
