我是C#的新手,我有一个PowerShell脚本,使用IP地址和用户名将文件发送到多台PC,我在那里使用new-PSDrive。我想在C#中创建相同的程序。
我不知道该怎么做,我经历了一些教程并尝试了它,但坚持使用Windows Impersonate Class。它写在我关注的帖子中:_如果我们想将文件共享到共享文件夹,我们可以使用 File.Copy(destPath,SourcePath),但它不起作用。
这是我正在尝试的代码:
WindowsIdentity idnt = new WindowsIdentity("Administrator", "Test123!");
WindowsImpersonationContext context = idnt.Impersonate();
File.Copy(@"C:\\Sent.txt", @"\\192.xxx.xxx.xxx\\SharedFolder", true);
context.Undo();
错误弹出式广告:提供的名称不是正确形成的帐户名称。 WindowsIdentity idnt =新的WindowsIdentity("管理员"," Test123!");
我不知道如何获得正确的名字,我正在尝试这样做: WindowsIdentity idnt =新的WindowsIdentity(用户名,密码);
我也是这个(" \ 192.xxx.xxx.xxx \ WIN-9SMSBCR4V7B \ SharedFolder",密码);
我要复制文件的机器在同一台机器上的Vmware上运行,我可以使用Powershell Script发送。
任何建议都将不胜感激。

您可能会认为将文件从一个文件夹复制到远程共享(需要用户名/密码)会很简单!但是,它不是!
以下2个链接提供了一些选项:
(1) How to provide user name and password when connecting to a network share
以上链接是关于首先映射网络驱动器然后执行文件复制
(2)copy files with authentication in c#
此选项是关于使用WindowsIdentity
类(正如您所尝试的)。上面的链接提供了一种以正确的方式构造对象的方法
在某种程度上,上述两种选择都不是纯粹的.Net解决方案。他们直接调用Win32 API。
另一种选择:
如果您可以先创建一个映射的网络连接(在应用程序之外),那么可以使用简单的文件副本。
在这种情况下,步骤将是:
(1)使用net use命令使用用户名和密码将驱动器映射到共享文件夹
net use Z: /delete
net use Z: \\server name\share name password /user:user name
(2)运行复制程序
File.Copy(sourceFileName, @"Z:\path\to\folder\filename");
(3)删除驱动器映射
net use Z: /delete
