Copy file to remote computer using remote admin credentials
提问by Casey Gay
I am using C#...
我正在使用 C#...
I need the ability to copy a set of files to about 500 unique computers. I have successfully been able to use the LogonUser() method to impersonate a domain account that has the required permissions to copy the files. The destination path for the files is something like:
我需要能够将一组文件复制到大约 500 台不同的计算机。我已经成功地能够使用 LogonUser() 方法来模拟具有复制文件所需权限的域帐户。文件的目标路径类似于：
\\RemoteComputer\C$\SomeFolder
\\远程计算机\C$\SomeFolder
My questions is...is there a way to do this without having to use an all-powerful domain account (these computers may not be joined to the domain in the future)? I have the local administrator accounts for every computer...is there a simple way to copy a file to a computer using it's LOCAL administrator account rather than a domain account?
我的问题是......有没有办法在不必使用全能域帐户的情况下做到这一点（这些计算机将来可能不会加入域）？我有每台计算机的本地管理员帐户......是否有一种简单的方法可以使用它的本地管理员帐户而不是域帐户将文件复制到计算机？

Correct me if I'm wrong, but you can use LogonUserto impersonate a local group also not only domain accounts.
如果我错了，请纠正我，但您可以使用LogonUser来模拟本地组，而不仅仅是域帐户。

WNetAddConnection2will do the trick. Just use an empty string for the local device name, to avoid mapping a drive. You also want to make sure and close the connectionwhen you're done. I wrap it into a NetworkConnection class that implements IDisposable.
WNetAddConnection2可以解决问题。只需对本地设备名称使用空字符串，以避免映射驱动器。您还想确保并在完成后关闭连接。我将它包装到一个实现 IDisposable 的 NetworkConnection 类中。
