サーバ上の共有フォルダの変更を行っているコンピュータのホスト名/ IPアドレスを知る方法

Question

サーバ上の共有フォルダを監視して、ネットワークに接続されたコンピュータがそのフォルダ内で行う変更を監視する必要がありますホスト名）。私はC＃を使ってディレクトリとファイルの監視を実装しました。しかし、Created、Renamed、Changed、Deleted、Errorイベントなどのイベントのみを監視します。 また、共有フォルダへのアクセスや変更を行ったコンピュータのホスト名/ IPアドレスと、イベントが発生した時刻を監視するのに役立つ必要があります。 は、ここに私のコードです：私はこのアプローチを試してみました

あなたは、少なくとも共有に接続されているものを取得するためにWMIを使用することができます。 System.Management.dllを参照し、ManagementObjectSearcherというインスタンスを作成してください。

問題は一般的に正しいクラスを見つけることであり、WMIの参照はWMI Referenceの下にあります。あなたの場合、Win32_ConnectionShareクラスが必要です。そのクラスからデータにアクセスするには、アプリケーションが管理者特権で実行する必要があることを考慮してください。

ご利用の場合のために少しのコード例（上記のドキュメントantecedentを述べに従ってdependentは、クライアント側を表しながら、サーバ側を表します）：

// Create a query for system environment variables only 
SelectQuery query = new SelectQuery("SELECT * FROM Win32_ConnectionShare"); 

// Initialize an object searcher with this query 
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query); 

// Get the resulting collection and loop through it 
foreach (ManagementObject mo in searcher.Get()) 
{ 
    string antecedent = mo["antecedent"].ToString(); 
    string dependent = mo["dependent"].ToString(); 

    ManagementObject share = new ManagementObject(antecedent); 
    ManagementObject server = new ManagementObject(dependent); 

    Console.WriteLine(server["UserName"].ToString()); 
    Console.WriteLine(server["ComputerName"].ToString()); 
    Console.WriteLine(server["ShareName"].ToString()); 
}
