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,然后循环直到找到我正在寻找的驱动器.
有一个更好的方法吗？
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
为什么不让你的WMI查询只回到name =’Y’？
所以：
Dim oQuery As System.Management.ObjectQuery = New System.Management.ObjectQuery("select FreeSpace,Name from Win32_LogicalDisk where DriveType=3 AND name='Y'")
