c# - 如何在C#中使用IP地址将文件传输到共享文件夹

Question

我是 C# 的新手，我有一个 PowerShell 脚本可以使用 IP 地址和用户名将文件发送到多台 PC，我正在使用 new-PSDrive。我想在 C# 中创建相同的程序。

我不确定该怎么做，我浏览了一些教程并进行了尝试，但仍然坚持使用 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(); 

弹出一个错误:提供的名称不是格式正确的帐户名称。 WindowsIdentity idnt = new WindowsIdentity("Administrator", "Test123!");

我不知道如何获得正确的名称，我正在尝试这样做:WindowsIdentity idnt = new WindowsIdentity(用户名,密码);

我也试过这个 ("\192.xxx.xxx.xxx\WIN-9SMSBCR4V7B\SharedFolder",Password);

我要复制文件的机器正在同一台机器上的 Vmware 上运行，我可以使用 Powershell 脚本发送。

如有任何建议，我们将不胜感激。

找到解决方案，这是使用 IP 地址、用户名和密码将文件发送到远程 PC 的完整代码，这些计算机不在同一域中。 Here the Link which explains the use of correct LOGON PROVIDER
