Question

我正在使用System.IO.File.Copy将文件复制到远程服务器上的c $。我需要为连接指定用户名/密码。有一个简单的方法吗？我曾希望System.IO.File.Copy接受凭证作为参数，但事实并非如此。我怎么能这样做？

Answer 1

您无法将凭据添加到system.io.file，但似乎有一种解决方法： http://forums.asp.net/t/1283577.aspx/1

以上链接的片段：

using (System.Security.Principal.WindowsImpersonationContext ctx = System.Security.Pricipal.WindowsIdentity.Impersonate(userTokenptr))

{
 //do your IO operations
 ctx.Undo();     
}

转换为vb.net：

Using ctx As System.Security.Principal.WindowsImpersonationContext = System.Security.Pricipal.WindowsIdentity.Impersonate(userTokenptr)
    'do your IO operations       
     ctx.Undo()
End Using

绝对最简单的做法是将此例程添加到您的代码中，然后在File.Copy之前调用它：

Private Sub Open_Remote_Connection(ByVal strComputer As String, ByVal strUsername As String, ByVal strPassword As String)
    '//====================================================================================
    '//using NET USE to open a connection to the remote computer
    '//with the specified credentials. if we dont do this first, File.Copy will fail
    '//====================================================================================
    Dim ProcessStartInfo As New System.Diagnostics.ProcessStartInfo
    ProcessStartInfo.FileName = "net"
    ProcessStartInfo.Arguments = "use \\" & strComputer & "\c$ /USER:" & strUsername & " " & strPassword
    ProcessStartInfo.WindowStyle = ProcessWindowStyle.Hidden
    System.Diagnostics.Process.Start(ProcessStartInfo)

    '//============================================================================
    '//wait 2 seconds to let the above command complete or the copy will still fail
    '//============================================================================
    System.Threading.Thread.Sleep(2000)
End Sub
