FileCopy到共享文件夹 [英] FileCopy to a shared folder

问题描述

当我尝试以下操作时：


System.IO.File.Copy（" C：\\test_read\\test.txt"，
" \\\\192.168.0.5 \\test_write\\test.txt"，false）


我收到UnauthorizedAccessException 。


但是，我似乎无法找到如何授权文件副本（即。

处理用户/通行证）。


我肯定必须有一种方法可以做到这一点，而无需编写一个

服务器应用程序，通过tcp / ip将传输的文件保存到本地

文件夹...


任何人？

When I try the following:

System.IO.File.Copy("C:\\test_read\\test.txt",
"\\\\192.168.0.5\\test_write\\test.txt", false)

I get an UnauthorizedAccessException.

I cannot however, seem to find out how to authorize the file copy (ie.
process the user/pass).

I''m sure there must be a way I can do this without resorting to writing a
server application that saves a transmitted file over tcp/ip to a local
folder...

Anyone?

推荐答案

尝试做一个净使用在那个UNC看看你是否可以访问它

首先..也检查写访问权限。这可能是您的NT用户的问题

权限。

Try doing a "net use" on that UNC to see whether you have access to it
first.. also check write access. This is probably an issue with your NT user
permissions.

对不起，我应该先详细说明。共享文件夹位于

Win2k3服务器上，该服务器配备了我是其管理员的SQL服务器。


我的客户端的部分解决方案是一个应用程序上传文件

到服务器以及成员信息和其他相关数据到SQL

服务器。没有求助于服务器应用程序，知道我的客户对b / b $ b不满意更先进的技术（即FTP），我想用了一个

安全共享文件夹，我的应用程序将文件复制到

是客户技能水平和

开发时间方面最简单的解决方案。


但是，C＃/ .NET中的应用程序编程对我来说是新的，并且在使用System.IO和System.Security.Permissions之后，我仍然看不到

找到一种从服务器请求身份验证的方法。

Sorry I should have elaborated first. The shared folder is located on a
Win2k3 server equipped with SQL server of which I am the administrator of.

Part of my solution for my client is for an application to upload documents
to the server as well as member information and other related data to the SQL
server. Without resorting to a server application, knowing that my clients
are not confident with more advanced technology (ie FTP), I figured use of a
secure shared folder to which my application will copy the documents to would
be the simplest solution in terms of both the client skill level and
development time.

However, appliaction programming in C#/.NET is new to me, and after
perusings System.IO and System.Security.Permissions I still can''t seem to
find a way to request authentication from the server.

如果您需要使用除当前登录到工作站的人员以外的凭据，那么你需要看一下

WindowsIdentity.Impersonate方法
