从网络驱动器连接/复制 [英] Connecting / Copying from network drive

问题描述

不太确定该如何处理.我研究了一下，但很快就提出来了.尝试在工作时连接到网络驱动器并复制最新的文件夹(更新到项目)对我来说，目录以\开头，但是当我将其添加到字符串变量时，它将无法连接，并且在我显示时不会显示尝试检查它.有这个过程吗?

Not totally sure how to approach this. I've researched a bit but I've come up short. Trying to connect to the network drives at work and copy out the newest folder (updates to a project) For me, the dir starts as \ but when i add that to a string variable it won't connect and won't display when i attempt to check it. is there a process to this?

这就是我所拥有的.而且在某种程度上一定是错误的.

This is what i have. And it has to be wrong in someway.

string updir = @"\\NetworkDrive\updates\xxxxx";

public void CopyAll(DirectoryInfo source, DirectoryInfo target)
    {

        try
        {
            //check if the target directory exists
            if (Directory.Exists(target.FullName) == false)
            {
                Directory.CreateDirectory(target.FullName);
            }

            //copy all the files into the new directory

            foreach (FileInfo fi in source.GetFiles())
            {
                fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
            }


            //copy all the sub directories using recursion

            foreach (DirectoryInfo diSourceDir in source.GetDirectories())
            {
                DirectoryInfo nextTargetDir = target.CreateSubdirectory(diSourceDir.Name);
                CopyAll(diSourceDir, nextTargetDir);
            }
            //success here
            copyall = true;    
        }

        catch (IOException ie)
        {
            //handle it here
            copyall = false;
        }
    }

我一直在用它来复制.而且效果很好.

i've been using that to copy. And it works well.

DateTime lastHigh = new DateTime(1900, 1, 1);
        string highDir;
        foreach (string subdir in Directory.GetDirectories(updir))
        {
            DirectoryInfo fi1 = new DirectoryInfo(subdir);
            DateTime created = fi1.LastWriteTime;

            if (created > lastHigh)
            {
                highDir = subdir;
                lastHigh = created;
            }
        }

，然后找到最新的文件夹.

and that to find the newest folder.

推荐答案

您可以尝试使用以下方法(指定网络共享的访问权限):

You can try with something like this (specifying access rights for the network share ):

string updir = @"\\NetworkDrive\updates\somefile";

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsIdentity identity = new WindowsIdentity(username, password);
WindowsImpersonationContext context = identity.Impersonate();

File.Copy(updir, @"C:\somefile", true);
