推荐答案完全使用@Alex K的P/Invoke建议,我只想发布一种通过net use命令进行管道传输的方法:
Totally go with @Alex K's P/Invoke suggestion, I just wanted to post a hack method of piping through the net use command:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim RemotePath = GetUncSourcePath("v"c) If String.IsNullOrEmpty(RemotePath) Then Trace.WriteLine("there was an error") Else Trace.WriteLine(RemotePath) End If Me.Close() End Sub Private Shared Function GetUncSourcePath(ByVal driveLetter As Char) As String If String.IsNullOrEmpty(driveLetter) Then Throw New ArgumentNullException("driveLetter") If (driveLetter < "a"c OrElse driveLetter > "z") AndAlso (driveLetter < "A"c OrElse driveLetter > "Z") Then Throw New ArgumentOutOfRangeException("driveLetter", "driveLetter must be a letter from A to Z") Dim P As New Process() With P.StartInfo .FileName = "net" .Arguments = String.Format("use {0}:", driveLetter) .UseShellExecute = False .RedirectStandardOutput = True .CreateNoWindow = True End With P.Start() Dim T = P.StandardOutput.ReadToEnd() P.WaitForExit() For Each Line In Split(T, vbNewLine) If Line.StartsWith("Remote name") Then Return Line.Replace("Remote name", "").Trim() Next Return Nothing End Function更多推荐
