我需要能够在非域环境中尝试在远程计算机上读取和写入文件时以编程方式进行身份validation。
当您在类似于\\ targetComputer \ C $ \ targetFolder或\\ targetComputer \ admin $（其中targetComputer不在域中）的Windows RUN提示符中input命令时，系统将提示您input用户名和密码。 一旦你input用户名和密码，你可以完全访问远程文件夹。
我怎样才能在C＃中以编程方式完成此身份validation？
我试过了..
– 人员，但似乎只能在域环境中工作。
–CMDKEY.exe，但它似乎也只能在域环境中工作。
必须有办法做到这一点，但我迄今为止没有运气search高和低。 也许我只是在寻找错误的东西？ 我确定我不是第一个有这个问题的人。 任何帮助将不胜感激。
谢谢！
编辑：
我想我只是发现了一个不同的SOpost，回答我的问题： 使用凭据从远程，不受信任的域访问共享文件（UNC）
我现在就要处理这个问题，看看它到底在哪里。
谢谢！
冒充与对等/局域网络一起工作。 我有一些默认的“工作组”的一些机器的典型家庭网络和一些如果我记得在安装时做一个名字。
这里是我从我的IIS服务器应用程序访问我的另一台计算机上的文件的代码（无需在两台计算机上拥有相同的用户和密码，从某处复制并修改以供我使用）：

using (var impersonation = new ImpersonateUser("OtherMachineUser", "OtherMachineName", "Password", LOGON32_LOGON_NEW_CREDENTIALS)) { var files = System.IO.Directory.GetFiles("\\OtherMachineName\fileshare"); }
