我如何从远程计算机的驱动器获得可用自由空间？ [英] How do I get the available FreeSpace from a drive from a remote computer?

问题描述

我想从远程计算机的D盘的自由空间。

接近年底，我得到一个ManagementException是由用户代码未处理未找到

这是给我的错误行：FS = M [自由空间]的ToString（）;

下面是我的代码：

  ConnectionOptions oConn =新ConnectionOptions（）; 
 
 oConn.Username =用户名; 
 oConn.Password =密码; 
 oConn.Authority =ntlmdomain：XXX; 
 
管理范围范围=新的管理范围（\\\\Remote_Computer\\root\\CIMV2，oConn）; 
 
 scope.Connect（）; 
 
的ObjectQuery查询=新的ObjectQuery（选择的DeviceID，卷名FROM的Win32_LogicalDisk那里的DeviceID ='D：'）; 
 
 ManagementObjectSearcher搜索=新ManagementObjectSearcher（范围，查询）; 
 
 ManagementObjectCollection queryCollection = searcher.Get（）; 
 
的foreach（在queryCollection的ManagementObject米）
 {这里
 //错误发生
 FS = M [自由空间]的ToString（）。 
 
 FREESPACE = Convert.ToInt64（FS）; 
} 
  

解决方案

我发现了什么问题了。

我的查询是错误的。我取代了它：

 选择自由空间FROM的Win32_LogicalDisk那里的DeviceID ='D：'
  

和问题解决了。

I'm trying to get the FreeSpace from the D drive of a remote computer.

Towards the end, I'm getting a ManagementException was unhandled by user code "Not Found"

This is the line that gives me the error: fs = m["FreeSpace"].ToString();

Here's my code:

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);
}

解决方案

I found out what the issue was.

My query was wrong. I replaced it with:

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

And problem solved.
