c＃如何確定特定登錄的Windows用戶的會話ID用戶

Question

就像標題所說，我想創建一個方法來搜索Windows用戶會話ID由域名\用戶名。

我已經完成了讀取當前登錄的用戶，但id不知道確定他們的會話ID。

我的目標是殺死特定用戶的會話。

Answer 1

創建一個命令行應用程序。 調用命令「查詢會話」並將結果存儲在例如sessionList的列表中。 比你可以說：

var sessionList = Process.Start("cmd", "c:\>query session").ToList(); 
 
sessionList = sessionList.Where(x => x.Username == "Piet") 
 
foreach(var item in sessionList) 
 
{ 
 
console.WriteLine(item.id) 
 
} 
 

也許你需要微調它一點點，但它將基於從代碼工作

Answer 2

：How do you retrieve a list of logged-in/connected users in .NET?

修改了一下，以下代碼將列出登錄用戶及其相應的會話ID。

class Program 
{ 
    static void Main(string[] args) 
    { 
     var userLogins = new UserLogins(); 

     // this code gets the users from localhost - 
     // can change this to a remote hostname on the network 
     var users = UserLogins.GetUsers("localhost"); 

     foreach (var user in users) 
     { 
      Console.WriteLine("User: " + user); 
     } 

     Console.ReadKey(); 

    } 

    public class UserLogins 
    { 

     [DllImport("wtsapi32.dll")]
