如何使用远程计算机上的状态登录用户 [英] how to get logged on users with their status on remote machine

问题描述

我正在寻找一种方法来获取在远程计算机上登录的用户.我很想知道他们是本地登录还是远程登录，但是最重要的是我必须知道他们的状态.我在网上看到了一些用VB编写的答案，但是我需要用C#. markdmak此处给出的解决方案看起来是一个不错的开始，但是它在VB中，并且仅查找远程会话.我有这段代码，可以作为一个开始，但是我想将LogonId耦合到用户名并查看其状态:

I'm looking for a way to get the users that are logged in on a remote machine. I would love to know if they are logged on localy or remotely, but most of all I MUST know their status. I saw some answers on the net that are written in VB, but I need it in c#. the solution given in markdmak answer here is looking like a good start, but it's in VB and it looks for remote sessions only. I have this piece of code, which can be a start, but I would like to couple the LogonId to a username and to see its status:

string fqdn = ""; // set!!!    
ConnectionOptions options = new ConnectionOptions();
options.EnablePrivileges = true;
// To connect to the remote computer using a different account, specify these values:
// these are needed in dev environment
options.Username = ConfigurationManager.AppSettings["KerberosImpersonationUser"];
options.Password = ConfigurationManager.AppSettings["KerberosImpersonationPassword"];
options.Authority = "ntlmdomain:" + ConfigurationManager.AppSettings["KerberosImpersonationDomain"];

ManagementScope scope = new ManagementScope("\\\\" + fqdn + "\\root\\CIMV2", options);
try
{
    scope.Connect();
}
catch (Exception ex)
{
    if (ex.Message.StartsWith("The RPC server is unavailable"))
    {
        // The Remote Procedure Call server is unavailable
        // cannot check for logged on users
        return false;
    }
    else
    {
        throw ex;
    }
}

SelectQuery query = new SelectQuery("Select * from Win32_LogonSession");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
ManagementObjectCollection results = searcher.Get();
bool returnVal = false;
foreach (ManagementObject os in results)
{
    try
    {
        if (os.GetPropertyValue("LogonId").ToString() != null && os.GetPropertyValue("LogonId").ToString() != "")
        {
            returnVal = true;
        }
    }
    catch (NullReferenceException)
    {
        continue;
    }
}
return returnVal;
}

我真正需要并且找不到的是一种使所有用户都位于远程计算机上及其状态的方法，这意味着:活动，已断开连接，已注销等.

What I really need and can't find, is a way of getting ALL users on a remote machine AND their status, meaning: Active, Disconnected, Logged-off, etc.

推荐答案

您可以将 Win32_LogonSession WMI类筛选用于

You can use the Win32_LogonSession WMI class filtering for the LogonType property with the value 2 (Interactive)

尝试此示例

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 = "remote-machine";
            ManagementScope Scope;

            if (!ComputerName.Equals("localhost", StringComparison.OrdinalIgnoreCase))
            {
                ConnectionOptions Conn = new ConnectionOptions();
                Conn.Username = "username";
                Conn.Password = "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 LogonId  FROM Win32_LogonSession Where LogonType=2");
            ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);

            foreach (ManagementObject WmiObject in Searcher.Get())
            {
                Console.WriteLine("{0,-35} {1,-40}", "LogonId", WmiObject["LogonId"]);// String
                ObjectQuery LQuery = new ObjectQuery("Associators of {Win32_LogonSession.LogonId=" + WmiObject["LogonId"] + "} Where AssocClass=Win32_LoggedOnUser Role=Dependent");
                ManagementObjectSearcher LSearcher = new ManagementObjectSearcher(Scope, LQuery);
                foreach (ManagementObject LWmiObject in LSearcher.Get())
                {
                    Console.WriteLine("{0,-35} {1,-40}", "Name", LWmiObject["Name"]);                    
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(String.Format("Exception {0} Trace {1}", e.Message, e.StackTrace));
        }
        Console.WriteLine("Press Enter to exit");
        Console.Read();
    }
}
}
