vb.net如何检查网络驱动器是否持久映射

发布于 2024-08-07 22:48:01 字数 391 浏览 6 评论 0原文

我使用以下代码在系统上布局网络驱动器。我想添加第三列以实现持久性，但在 vb.net 中我不知道如何检查驱动器是否具有持久性映射。有什么建议吗？

For Each drive_info As DriveInfo In DriveInfo.GetDrives()
        If drive_info.DriveType().ToString = "Network" Then
            With maps.Items.Add(drive_info.Name)
                .SubItems.Add(drive_info.DriveType().ToString)
            End With
        End If
    Next drive_info

I use the following code to layout network drives on a system. I want to add a third column for persistence but in vb.net I do not know how to check if a drive has a persistent map or not. Any suggestions?

For Each drive_info As DriveInfo In DriveInfo.GetDrives()
        If drive_info.DriveType().ToString = "Network" Then
            With maps.Items.Add(drive_info.Name)
                .SubItems.Add(drive_info.DriveType().ToString)
            End With
        End If
    Next drive_info

您本来可以在 WMI 中完成此操作，而无需任何（好吧，更少）令人讨厌的麻烦。

例如，

Imports System
Imports System.Management

Public Module modmain
   Sub Main()
    Dim searcher As New ManagementObjectSearcher("SELECT * FROM Win32_NetworkConnection WHERE LocalName = 'Z:'")
    Dim obj As ManagementObject
    For Each obj In searcher.Get
        Console.WriteLine("{0} {1}", obj.Item("LocalName").ToString, obj.Item("Persistent"))
    Next
   End Sub
End Module

显然您需要添加对 System.Management.dll 的引用并将 Z: 更改为您正在检查的驱动器，或者您可能可以仅使用该代码片段替换所有代码，因为删除 WHERE 子句将返回所有映射的驱动器。

You could have always done it in WMI without any (well okay fewer) nasty cludges.

e.g.

Imports System
Imports System.Management

Public Module modmain
   Sub Main()
    Dim searcher As New ManagementObjectSearcher("SELECT * FROM Win32_NetworkConnection WHERE LocalName = 'Z:'")
    Dim obj As ManagementObject
    For Each obj In searcher.Get
        Console.WriteLine("{0} {1}", obj.Item("LocalName").ToString, obj.Item("Persistent"))
    Next
   End Sub
End Module

Obviously you need to add a reference to System.Management.dll and change Z: to the drive you are checking, or you could probably replace all your code with just that snippet as removing the WHERE clause will return all mapped drives.
