在C＃中使用FileSystemWatcher时如何获取用户名？ [英] How can I obtain the username when using a FileSystemWatcher in C#

问题描述

我正在使用FileSystemWatcher来监控网络上的共享文件夹。三台PC将共享此文件夹，并观看谁访问了什么。

我可以通过使用GetAccessControl函数读取用户名'创建功能'

I am using a FileSystemWatcher to monitor a share folder on network. Three PC will share this folder and watch who accessing what.
I could read user name by using GetAccessControl function for 'Create function'

protected void mywatcher_created(object sender,FileSystemEventArgs  e)
{
    string user_name = System.IO.File.GetAccessControl(e.FullPath).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
    
    DateTime current = DateTime.Now;
    lstCreate.Items.Add(e.FullPath.ToString());
    lstCreate.Items[cCount].SubItems.Add(current.ToShortDateString());
    lstCreate.Items[cCount].SubItems.Add(current.ToShortTimeString());
    lstCreate.Items[cCount].SubItems.Add(user_name.ToString());
    cCount += 1;
}

如果我想读取已删除，重命名或更改的文件的用户名，则不能使用GetAssessControl函数。我得到了'filepath找不到'的错误。

那么如何读取共享文件夹的用户名。

我用这个函数写了删除文件，

If I want to read user name for deleted , renamed or changed file , and GetAssessControl Function couldn't be used for those. I got error of 'filepath couln't find'.
So how can I read the user name of share folder.
I wrote deleted file by this function ,

protected void mywatcher_deleted(object sender, FileSystemEventArgs e)
       {

               string user_name = System.IO.File.GetAccessControl(e.FullPath).GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();

               CheckForIllegalCrossThreadCalls = false;
               DateTime current = DateTime.Now;
               lstDelete.Items.Add(e.FullPath.ToString());
               lstDelete.Items[dCount].SubItems.Add(current.ToShortDateString());
               lstDelete.Items[dCount].SubItems.Add(current.ToShortTimeString());
               lstDelete.Items[dCount].SubItems.Add(user_name.ToString());

               dCount += 1;
       }

推荐答案

由于NTFS不跟踪谁删除，重命名或修改文件，所以你无法获得用户名。它只跟踪谁拥有该文件。



此外， CheckForIllegalCrossThreadCalls = false 行是什么？你永远都不应该受到客户的惩罚，不管是出于何种目的使用这行代码。

Since NTFS doesn't track who deletes, renames, or modifies a file, so there's no way you can get the username. It only keeps track of who OWNS the file.

Also, what's with the "CheckForIllegalCrossThreadCalls = false" line? You should NEVER EVER, under penalty of clients ripping your eyeballs out, use that line of code for any purpose whatsoever.
