c# - 如何从远程计算机的驱动器获取可用的 FreeSpace？

Question

我正在尝试从远程计算机的 D 盘获取 FreeSpace。

最后，我得到一个 ManagementException 未被用户代码“未找到”处理

这是给我错误的行: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);
}

Answer 1

我发现了问题所在。

我的查询是错误的。我将其替换为:

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

问题解决了。
