进程是否在远程机器上运行？

Question

我有三台远程连接的远程 PC。我正在尝试编写一个简单的 Windows 应用程序，该应用程序将在单个窗口中显示特定进程是否在任何一台机器上运行，例如

Server1：Chrome 未运行

Server2：Chrome 正在运行

Server3：Chrome 正在运行

我使用了 WMI 和 C#。到目前为止，我有这么多：

            ConnectionOptions connectoptions = new ConnectionOptions();

            connectoptions.Username = @"domain\username";
            connectoptions.Password = "password";

            //IP Address of the remote machine
            string ipAddress = "192.168.0.217";
            ManagementScope scope = new ManagementScope(@"\\" + ipAddress + @"\root\cimv2");
            scope.Options = connectoptions;
            //Define the WMI query to be executed on the remote machine
            SelectQuery query = new SelectQuery("select * from Win32_Process");

            using (ManagementObjectSearcher searcher = new
                        ManagementObjectSearcher(scope, query))
            {

                ManagementObjectCollection collection = searcher.Get();
                foreach (ManagementObject process in collection)
                {
                    // dwarfs stole the code!! :'(                        
                }
            }

我认为这一切都设置正确，但如果我在 foreach 循环中使用 MessageBox.Show(process.ToString())，我会得到一大堆带有以下文本的消息框：

\\username\root\cimv2:W32_Process.Handle="XXX"

我有点卡住了。有什么方法可以将 XXX“翻译”为进程名称？否则，如何才能真正获取进程的名称，以便我可以使用 if 语句来检查它是否是“chrome”进程？

或者...我的实现是不是有点矫枉过正？有没有更简单的方法来做到这一点？

非常感谢！

Answer 1

在你的 foreach 中，试试这个：

Console.WriteLine(process["Name"]);

Answer 2

可以在WQL语句中过滤要观察的进程名，这样就可以这样写

 SelectQuery query = new SelectQuery("select * from Win32_Process Where Name='Chrome.exe'");

试试这个示例应用

using System;
using System.Collections.Generic;
using System.Management;
using System.Text;

namespace GetWMI_Info
{
    class Program
    {

        static void Main(string[] args)
        {
            try
            {
                string ComputerName = "localhost";
                ManagementScope Scope;                

                if (!ComputerName.Equals("localhost", StringComparison.OrdinalIgnoreCase)) 
                {
                    ConnectionOptions Conn = new ConnectionOptions();
                    Conn.Username  = "";
                    Conn.Password  = "";
                    Conn.Authority = "ntlmdomain:DOMAIN";
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), Conn);
                }
                else
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);

                Scope.Connect();
                ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_Process Where Name='Chrome.exe'");
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);


                foreach (ManagementObject WmiObject in Searcher.Get())
                {
                  //for each instance found, do something  
                  Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
            }
            Console.WriteLine("Press Enter to exit");
            Console.Read();
        }
    }
}

试试Process.GetProcesses("chrome", "computerName")；

在 System.Diagnostics.Process 中定义为

public static Process[] GetProcessesByName(
   string processName,
   string machineName)
