在C＃中找出修改过的用户名文件

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

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- 它是COM参考

这是有关如何调用该方法的一些示例：

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Exception在
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”
