找出用户名（谁）在C＃中修改过的文件 [英] Find out username(who) modified file in C#

问题描述

我使用的是FileSystemWatcher的监视文件夹。但是，当有一些事件在目录中进行，我不知道如何寻找谁做在该文件中的冲击。我尝试使用事件日志。它只是不能工作。是否有另一种方式做到这一点？

I am using a FileSystemWatcher to monitor a folder. But when there is some event happening in the directory, I don't know how to search who made a impact on that file. I tried to use EventLog. It just couldn't work. Is there another way to do it?

推荐答案

我不记得在那里我发现这个code，但其使用的PInvoke我认为这是这个任务有点大材小用的替代品。使用 FileSystemWatcher的来观看该文件夹，当一个事件触发，你可以制定出使用这种code哪些用户所做的文件更改：

I cant remember where I found this code but its an alternative to using pInvoke which I think is a bit overkill for this task. Use the FileSystemWatcher to watch the folder and when an event fires you can work out which user made the file change using this code:

private string GetSpecificFileProperties(string file, params int[] indexes)
{
    string fileName = Path.GetFileName(file);
    string folderName = Path.GetDirectoryName(file);
    Shell32.Shell shell = new Shell32.Shell();
    Shell32.Folder objFolder;
    objFolder = shell.NameSpace(folderName);
    StringBuilder sb = new StringBuilder();

    foreach (Shell32.FolderItem2 item in objFolder.Items())
    {
        if (fileName == item.Name)
        {
            for (int i = 0; i < indexes.Length; i++)
            {
                sb.Append(objFolder.GetDetailsOf(item, indexes[i]) + ",");
            }

            break;
        }
    }

    string result = sb.ToString().Trim();
    //Protection for no results causing an exception on the `SubString` method
    if (result.Length == 0)
    {
        return string.Empty;
    }
    return result.Substring(0, result.Length - 1);
}

SHELL32是DLL的引用：微软壳牌控制和自动化 - 它是一个COM引用

下面是你如何调用该方法的一些示例的：

Here is some example's of how you call the method:

string Type = GetSpecificFileProperties(filePath, 2);
string ObjectKind = GetSpecificFileProperties(filePath, 11);
DateTime CreatedDate = Convert.ToDateTime(GetSpecificFileProperties(filePath, 4));
DateTime LastModifiedDate = Convert.ToDateTime(GetSpecificFileProperties(filePath, 3));
DateTime LastAccessDate = Convert.ToDateTime(GetSpecificFileProperties(filePath, 5));
string LastUser = GetSpecificFileProperties(filePath, 10);
string ComputerName = GetSpecificFileProperties(filePath, 53);
string FileSize = GetSpecificFileProperties(filePath, 1);
