我有 VB.NET 代码,用于将驱动器映射到网络路径。
strPath = "\\11.22.33.11\Hostsw\Host\SW\"
当我使用以下函数调用 MapDrive("T", strpath, "pcs", "$pcspcs$")
时,会出现错误消息 “错误的路径无法连接到明星目录”
。
Public Declare Function WNetAddConnection2 Lib "mpr.dll" Alias "WNetAddConnection2A" (ByRef lpNetResource As NETRESOURCE, ByVal lpPassword As String, ByVal lpUserName As String, ByVal dwFlags As Integer) As Integer
Public Declare Function WNetCancelConnection2 Lib "mpr" Alias "WNetCancelConnection2A" (ByVal lpName As String, ByVal dwFlags As Integer, ByVal fForce As Integer) As Integer
Public Const ForceDisconnect As Integer = 1
Public Const RESOURCETYPE_DISK As Long = &H1
Private Const ERROR_BAD_NETPATH = 53&
Private Const ERROR_NETWORK_ACCESS_DENIED = 65&
Private Const ERROR_INVALID_PASSWORD = 86&
Private Const ERROR_NETWORK_BUSY = 54&
Public Structure NETRESOURCE
Public dwScope As Integer
Public dwType As Integer
Public dwDisplayType As Integer
Public dwUsage As Integer
Public lpLocalName As String
Public lpRemoteName As String
Public lpComment As String
Public lpProvider As String
End Structure
Public Function MapDrive(ByVal DriveLetter As String, ByVal UNCPath As String, ByVal strUsername As String, ByVal strPassword As String) As Boolean
Dim nr As NETRESOURCE
nr = New NETRESOURCE
nr.lpRemoteName = UNCPath
nr.lpLocalName = DriveLetter & ":"
nr.lpProvider = Nothing
nr.dwType = RESOURCETYPE_DISK
Dim result As Integer
result = WNetAddConnection2(nr, strPassword, strUsername, 0)
If result = 0 Then
Return True
Else
Select Case result
Case ERROR_BAD_NETPATH
PostBackMessageHiddenField.Value = "QA4001I Bad path could not connect to Star Directory"
Case ERROR_INVALID_PASSWORD
PostBackMessageHiddenField.Value = "QA4002I Invalid password could not connect to Star Directory"
Case ERROR_NETWORK_ACCESS_DENIED
PostBackMessageHiddenField.Value = "QA4003I Network access denied could not connect to Star Directory"
Case ERROR_NETWORK_BUSY
PostBackMessageHiddenField.Value = "QA4004I Network busy could not connect to Star Directory"
End Select
Return False
End If
End Function
Public Function UnMapDrive(ByVal DriveLetter As String) As Boolean
Dim rc As Integer
rc = WNetCancelConnection2(DriveLetter & ":", 0, ForceDisconnect)
If rc = 0 Then
Return True

Return False

最佳答案
研究解决方案是首先查看方法的 P/Invoke 定义
http://www.pinvoke.net/default.aspx/mpr.wnetaddconnection2
http://pinvoke.net/default.aspx/Structures/NETRESOURCE.html
并确保您的方法定义正确。例如,您使用 Integer
而不是 UInt32
等等。
一个快速、肮脏但有效的解决方案是不要重新发明轮子,而是使用每个 Windows 安装中包含的 net
工具:
Module Module1
Public Sub MapDrive(ByVal DriveLetter As String, ByVal UNCPath As String, ByVal strUsername As String, ByVal strPassword As String)
Dim p As New Process()
p.StartInfo.FileName = "net.exe"
p.StartInfo.Arguments = " use " & DriveLetter & ": " & UNCPath & " " & strPassword & " /USER:" & strUsername
p.StartInfo.CreateNoWindow = True
p.Start()
p.WaitForExit()
End Sub
Sub Main()
MapDrive("x", "\\FoosServer\FoosShare", "FoosServer\Bob", "correcthorsebatterystaple")
End Sub
End Module
代码的作用是,它使用正确的参数运行 net.exe
(路径包含在 PATH
环境变量中,因此不需要包含它)(例如 net use x:\\Server\share password/USER:domain\Username
),然后这会映射您的网络驱动器。
