为什么我得到未知错误1346？ [英] Why I am getting unknown error 1346?

问题描述

为什么我收到未知错误1346？



模拟代码后，我将从本地驱动器复制文件到网络驱动器时遇到异常1346。如果注释了相同的代码，则文件将被成功复制。我想在冒充之后做同样的事情。凭证和所有凭证都有效。



以下是我的代码：

  string  serverName = CheckUNCPath（  Z：）; 
  string  username =  @  Alexander.junior @ chn.nestgroup.net; 
 
  //   string username =alexander.junior;  
  string  password =   [已删除] *; 
 AppDomain.CurrentDomain.SetPrincipalPolicy（PrincipalPolicy.WindowsPrincipal）; 
 WindowsIdentity identity =  new  WindowsIdentity（用户名，密码）; 
 WindowsImpersonationContext context = identity.Impersonate（）; 
 
  string  updir = serverName; 
  string  destPath =  @  D：\\ \\Alex_BackUp\Test\test1.txt; 
 File.Copy（destPath，updir， true ）;

要么假冒等级是未提供，或提供的模拟级别无效。

我知道您认为用户名和密码是正确的，但有些不对。也许他们没有足够的权限。也许用户名应该是domain \ username。不确定，但你必须在最后解决它。

如果我没记错，普通用户帐户不能冒充其他用户。管理员帐户可以。



您运行此代码的帐户必须拥有 SeImpersonatePrivilege 才能冒充其他人。要查看该帐户是否具有此权限，请打开CMD提示并输入：

 WHOAMI / PRIV 
 

你会得到这样的东西：

 Microsoft Windows [Version 10.0.10586] 
（c）2015 Microsoft Corporation。版权所有。 
 
 C：\ Users \XXXXXXXX> whoami / priv

如果您没有列出 SeImpersonatePrivilege ，则该帐户无法模仿其他人

Why I am getting unknown error 1346?

After the Impersonation code I am getting exception 1346 on copying file from a local drive to a network drive. If the same code is commented the file is getting copied successfully. I want to do the same after impersonation. The credentials and all are valid.

Below is my code:

 string serverName=CheckUNCPath("Z:");
 string username = @"[e-mail]";

  //string username = "alexander.junior";
  string password = "[removed]*";
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsIdentity identity = new WindowsIdentity(username, password);
WindowsImpersonationContext context = identity.Impersonate();

string updir = serverName;
string destPath = @"D:\Alex_BackUp\Test\test1.txt";
File.Copy(destPath,updir,true);

Either a required impersonation level was not provided, or the provided impersonation level is invalid.

I know you think the username and password are correct, but something isn't right. Perhaps they don't have enough permissions. Perhaps username should be domain\username instead. Not sure, but you'll have to troubleshoot it on your end.

If I remember correctly, normal user account cannot impersonate other users. Administrator accounts can.

The account you're running this code under has to have the SeImpersonatePrivilege in order to impersonate someone else. To see if the account has this privilege, open a CMD prompt and type:

WHOAMI /PRIV

You'll get something like this:

Microsoft Windows [Version 10.0.10586]
(c) 2015 Microsoft Corporation. All rights reserved.

C:\Users\XXXXXXXX>whoami /priv

If you don't have the SeImpersonatePrivilege listed the account cannot impersonate someone else.
