How to present credentials in order to open file?
提问by
How do I specify the username and password in order for my program to open a file for reading? The program that needs to access the file is running from an account that does not have read access to the folder the file is in. Program is written in C# and .NET 2, running under XP and file is on a Windows Server 2003 machine.

You can impersonate a user who has the necessary rights. There is an article on MSDNthat describes how to do this.

You want to impersonate a user who does have the rights to access the file.
您想模拟一个有权访问该文件的用户。
I recommend using a class like this - http://www.codeproject.com/KB/cs/zetaimpersonator.aspx. It hides all the nasty implementation of doing impersonation.
我建议使用这样的类 - http://www.codeproject.com/KB/cs/zetaimpersonator.aspx。它隐藏了模仿的所有讨厌的实现。
using (new Impersonator("myUsername", "myDomainname", "myPassword"))
{
string fileText = File.ReadAllText("c:\test.txt");
Console.WriteLine(fileText);
}

I have used the Nuget package NuGet Gallery | Simple Impersonation Library 1.1.0but there are others; search on Impersonation for the others.
我使用过 Nuget 包NuGet Gallery | Simple Impersonation Library 1.1.0但还有其他的；在 Impersonation 上搜索其他人。
Example usage using the interactive login to work with file structures:
使用交互式登录来处理文件结构的示例用法：
using (Impersonation.LogonUser("{domain}",
"{UserName}",
"{Password}",
LogonType.Interactive))
{
var directory = @"\MyCorpServer.net\alpha\cars";
Assert.IsTrue(Directory.Exists(directory));
}
James' answer below was before Nuget and before he would later have the most downloaded package on Nuget. Ironic eh?
下面詹姆斯的回答是在 Nuget 之前，在他后来在 Nuget 上下载最多的软件包之前。讽刺啊？
