Get file to FileStream from remote path with another user credentials
提问by Tschareck
In my application I use FileStreamto read from a file, that is on the fileshare somewhere in the network. So my remoteFilePathvariable is something like: \\computername\folder\file.pdf
在我的应用程序中，我FileStream用来读取文件，该文件位于网络中某处的文件共享上。所以我的remoteFilePath变量是这样的：\\computername\folder\file.pdf
FileStream fileStream = new FileStream(remoteFilePath, FileMode.Open, FileAccess.Read, FileShare.None, 1024 * 1024)
Unfortunately, the user that I'm running this application with (that I'm logged into the PC with) does not have access to this fileshare. I have another user (domain, login & password), that has access to those files.
不幸的是，与我一起运行此应用程序的用户（我登录到 PC 时使用的用户）无权访问此文件共享。我有另一个用户（域、登录名和密码），可以访问这些文件。
Is it possible to use the other user credentials to get a file to filestream? Can I impersonate the user onlyto get a file, and then continue with my own user?
是否可以使用其他用户凭据将文件获取到文件流？我可以模拟用户只是为了获取文件，然后继续使用我自己的用户吗？

Thank you for your answers. Since the share was in another domain, it was not so easy to impersonate.
谢谢您的回答。由于共享位于另一个域中，因此冒充并不容易。
I found another, easier solution. I mapped a network drive, and checked the option Connect using different credentials. Then I connect to this drive instead of the remote path.
我找到了另一个更简单的解决方案。我映射了一个网络驱动器，并选中了选项Connect using different credentials。然后我连接到这个驱动器而不是远程路径。
string mappedFilePath = filePath.Replace(@"\computername\", @"Y:\")
and use this new string in FileStreamconstructor.
并在FileStream构造函数中使用这个新字符串。

You should use impersonation. More info at http://msdn.microsoft.com/en-us/library/w070t6ka.aspx
