问题 In my uwp app I am getting Video files with KnownFolders.VideoLibrary . I am able to PreFetch videoProperties of the file and also some other properties. Now I actually want to tag the video files with some string data, and save that data so I can check that later on. For example I want to add them to Liked Videos so can I add a custom property on the storagefile which will remain saved every time I run the app. This will let me check whether a specific storagefile is liked or not. Currently

问题 I am trying to get the BPM property from an MP3 file: I can see how to do this in a Windows Store App as per this question: How to read Beats-per-minute tag of mp3 file in windows store apps C#? but can't see how to use Windows.Storage in a Windows Forms app. (If I understand it correctly it's because Windows.Storage is specific to UWP.) How can I read this in a Forms app? Happy to use a (hopefully free) library if there is nothing native. 回答1: You can use Windows' Scriptable Shell Objects

问题 I would like to set properties as shown in Windows Explorer File Properties->Summary Tab (Authors, Title, Subject, etc).

问题 I am trying to read "Bit rate" property of audio files. I know how to get the value but the way I am doing it I don't think is the most efficient. Shell shell = new Shell32.Shell(); Folder objFolder = shell.NameSpace(path); for (int i = 0; i < short.MaxValue; i++) { string property = objFolder.GetDetailsOf(null, i); if (String.IsNullOrEmpty(property)) break; if (property.Equals("Bit rate")) { index = i; break; } } FolderItem item = objFolder.ParseName(fileName); string bitRateValue =

问题 I would like to find the height/width of an image on disk without opening it, if possible (for performance reasons). The Windows properties pane for images contains information like width, height, bit depth, etc., which leads me to believe that it is storing metadata on the file somewhere. How can I access this information? 回答1: There are some stackoverflow questions on how to read the EXIF information from images, such as: How to get the EXIF data from a file using C# 回答2: Use System.Drawing

问题 When using Windows Explorer to view files, I'm given the option to set a "tag", "category", or other attributes. For a JPEG a different set of attributes (including "tag") are options. I'd like to be able to set these programmatically. How do I programmatically set a file tag and other file attributes using Delphi (I have Delphi 2010 Pro)? 回答1: Tags in JPEG files are stored as IPTC keywords. There are a few libraries available for reading and writing those, if that's what you're asking for.

问题 If one looks at file properties in Windows Explorer, the "Details" tab, - for many filetypes (for example, tiff or jpeg images, Office documents, etc.) there is the "Description" section with fields like "Title", "Subject", "Tags", and "Comments". Is there a way to read/write these fields from Perl or a PowerShell script? 回答1: PowerShell has gone through some iterations, and this can now be achieved with a native command: Get-ItemProperty Example: Shows the current details of ntdll.dll file:
