如何获取登录用户及其在远程计算机上的状态
如何获取登录用户及其在远程计算机上的状态
提问于 2013-01-08 17:46:11
我正在寻找一种方法，让用户登录到远程机器上。我很想知道他们是本地登录还是远程登录，但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写的答案，但我需要用c#写的。在markdmak answer here中给出的解决方案看起来是一个很好的开始，但它是用VB编写的，而且它只寻找远程会话。我有这段代码，这可能是一个开始，但我想将LogonId耦合到用户名并查看其状态：
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;
}我真正需要但找不到的，是一种获取远程机器上所有用户及其状态的方法，这意味着:活动、断开连接、注销等。

可以对值为2(交互式)的LogonType属性使用Win32_LogonSession WMI类筛选
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();
}
}
