如何在 C# 中检测从一台服务器到另一台服务器的可用空间和磁盘信息

Question

如果网络上有 3 台电脑，并且我想从另一台电脑检测一台电脑的可用空间和磁盘详细信息，那么该怎么做... 我找到了这段代码。但我不知道我应该如何测试它才能知道它是否有效。 这是正确的方法吗？

public Hashtable ReadFreeSpaceOnNetworkDrives()
{
     //create Hashtable instance to hold our info
     Hashtable driveInfo = new Hashtable();
     //query the win32_logicaldisk for type 4 (Network drive)
     SelectQuery query = new SelectQuery("select name, FreeSpace from win32_logicaldisk where drivetype=4");

     //execute the query using WMI
     ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
     //loop through each drive found
     foreach (ManagementObject drive in searcher.Get())
     {
        //add the name & freespace to our hashtable
        driveInfo.Add("Drive", drive["name"]);
        driveInfo.Add("Space", drive["FreeSpace"]);
     }
     return driveInfo;
}

更新：

我得到了问题的答案，但我得到了代码，但它在控制台应用程序中，我希望在 Windows 窗体应用程序中使用磁盘空间和驱动器信息的图形表示。我该如何使用此代码并开始执行此操作？

        ManagementScope scope = new ManagementScope("\\\\10.74.160.126\\root\\cimv2");
        scope.Connect();

        ObjectQuery query = new ObjectQuery( "SELECT * FROM Win32_OperatingSystem");
        SelectQuery query1 = new SelectQuery("Select * from Win32_LogicalDisk");

        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

        ManagementObjectCollection queryCollection = searcher.Get();

        ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);
        ManagementObjectCollection queryCollection1 = searcher1.Get(); 

        foreach (ManagementObject m in queryCollection)
        {
            // Display the remote computer information
            Console.WriteLine("Computer Name : {0}",
                m["csname"]);
            Console.WriteLine("Windows Directory : {0}",
                m["WindowsDirectory"]);
            Console.WriteLine("Operating System: {0}",
                m["Caption"]);
            Console.WriteLine("Version: {0}", m["Version"]);
            Console.WriteLine("Manufacturer : {0}", m["Manufacturer"]);
            Console.WriteLine();

            }

        foreach (ManagementObject mo in queryCollection1)
        {
            Console.WriteLine("  Disk Name : {0}", mo["Name"]);
            Console.WriteLine("   Disk Size : {0}", mo["Size"]); 
            Console.WriteLine("  FreeSpace : {0}", mo["FreeSpace"]);
            Console.WriteLine("  Disk DeviceID : {0}", mo["DeviceID"]); 
            Console.WriteLine("  Disk VolumeName : {0}", mo["VolumeName"]);
            Console.WriteLine("  Disk SystemName : {0}", mo["SystemName"]); 
            Console.WriteLine("Disk VolumeSerialNumber : {0}", mo["VolumeSerialNumber"]);
            Console.WriteLine(); 
        }
        Console.ReadLine();
        }

Answer 1

代码检查运行此程序的电脑上的所有驱动器。它返回一个表，每个驱动器有 2 个条目。一个带有名称，一个带有可用空间。您可以编写一个使用此方法并显示此数据的简单程序。应该可以从远程计算机查询驱动器。或许这篇文章能告诉你更多http://msdn.microsoft.com/en-us/library/ms257337%28v=vs.80%29.aspx

public Hashtable ReadFreeSpaceOnNetworkDrives(String FullComputerName)
{
     ManagementScope scope = new ManagementScope(fullComputerName);
     scope.Connect();
     //create Hashtable instance to hold our info
     Hashtable driveInfo = new Hashtable();
     //query the win32_logicaldisk for type 4 (Network drive)
     SelectQuery query = new SelectQuery("select name, FreeSpace from win32_logicaldisk where drivetype=4");

     //execute the query using WMI
     ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope,query);
     //loop through each drive found
     foreach (ManagementObject drive in searcher.Get())
     {
        //add the name & freespace to our hashtable
        driveInfo.Add("Drive", drive["name"]);
        driveInfo.Add("Space", drive["FreeSpace"]);
     }
     return driveInfo;
}
