我不记得我在哪里找到了这段代码，但是它是使用pInvoke的替代方法，我认为这对于执行此任务有些过分了。使用FileSystemWatcher监视文件夹，当事件触发时，您可以使用以下代码确定哪个用户更改了文件：
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是对DLL的引用：Microsoft Shell Controls and Automation-
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);
或将多个逗号分隔的属性放在一起：
string SizeTypeAndLastModDate = GetSpecificFileProperties(filePath, new int[] {1, 2, 3});
注意：此解决方案已在Windows 7和Windows 10上进行了测试。除非使用Shell32获取文件扩展属性时按照Except455 STA上运行，否则该解决方案将无法工作，并且您将看到以下错误：
无法将类型为“ Shell32.ShellClass”的COM对象转换为接口类型为“ Shell32.IShellDispatch6”
