查询远程服务器上磁盘空间的最佳方式

Question

我试图通过查询所有驱动器来确定远程服务器上的可用空间，然后循环直到找到正在寻找的驱动器。有一个更好的方法吗？

Dim oConn As New ConnectionOptions 

Dim sNameSpace As String = "\\mnb-content2\root\cimv2" 

Dim oMS As New ManagementScope(sNameSpace, oConn) 

Dim oQuery As System.Management.ObjectQuery = New System.Management.ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3") 

Dim oSearcher As ManagementObjectSearcher = New ManagementObjectSearcher(oMS, oQuery) 


Dim oReturnCollection As ManagementObjectCollection = oSearcher.Get() 

Dim oReturn As ManagementObject 

For Each oReturn In oReturnCollection 
      'Disk name 
      Console.WriteLine("Name : " + oReturn("Name").ToString()) 
      'Free Space in bytes 
      Dim sFreespace As String = oReturn("FreeSpace").ToString() 
      If Left(oReturn("Name").ToString(), 1) = "Y" Then 
       Console.WriteLine(sFreespace) 
      End If 
Next 

Answer 1

为什么不只是让你的WMI查询只能拉回name ='Y'？

所以：

Dim oQuery As System.Management.ObjectQuery = New System.Management.ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3 AND name='Y'")
