c# – 如何从远程计算机的驱动器获取可用的FreeSpace？

2023年8月5日 210次阅读

我正试图从远程计算机的D盘中获取FreeSpace.

接近尾声,我收到一个ManagementException未被用户代码“Not Found”处理

这是给出错误的行：fs = m [“FreeSpace”].ToString();

这是我的代码：

ConnectionOptions oConn = new ConnectionOptions();

oConn.Username = "username";
oConn.Password = "password";
oConn.Authority = "ntlmdomain:XXX";

ManagementScope scope = new ManagementScope("\\\\Remote_Computer\\root\\CIMV2", oConn);

scope.Connect();

ObjectQuery query = new ObjectQuery("SELECT DeviceID, VolumeName FROM Win32_LogicalDisk where DeviceID = 'D:'");

ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

ManagementObjectCollection queryCollection = searcher.Get();

foreach (ManagementObject m in queryCollection)
{
      //error happens here
      fs = m["FreeSpace"].ToString();

      freeSpace = Convert.ToInt64(fs);
}

最佳答案 我发现了问题所在.

我的查询错了.我把它替换为：

"SELECT FreeSpace FROM Win32_LogicalDisk where DeviceID = 'D:'"

问题解决了.
