How to play a music by click on it (wpf , c#)

IKINGSHADOW 136

Hello everyone , So i have a music player that can find musics from the folders that the user added in the application and then the user can play them in the application but my question is , how can i play the musics just by click on them without my application running ( like windows music player ) , for example in windows 10 if you double click on a music file it will be play in groove , so how can i do that , ( i know that there are contents on the internet about this but I don't know what should i search about.) How can i play musics when the user double click on files in two situations , first when my application is ruining , second when my application isn't running ??

Windows just launches the associated application, from Settings (stored in the Registry)
For example, .mp3 files on my PC are associated with WMP :

You wrote "when the user double click on files"
When a user double-clicks on a file, Windows (the Shell) calls IQueryAssociations
to read in the registry the application associated with the extension and to launch it

As i read the article this interface is useless because it won't retrive the files location , as you know the player need a uri adress for playing a music file but this interface just retrive the file extension not address , is there any interface or method or class that retrive the address of the files that the user double clicked on it to open it ???

this interface just retrive the file extension

No, as I said, it finds the associated executable from the extension.
If you associate .mp3 with your .exe, the Shell will launch the .exe with the .mp3 as argument

I just found the solution for my problem by helping of other people in this community and stackoverflow ,
Also this link provides the solution :
https://stackoverflow.com/questions/58383027/how-to-start-my-program-and-read-text-file-by-clicking-the-file-from-desktop
According to this solution thw windows will pass the address of the file through the application.startup , and we can retrieve the path from startupeventsargs.args ,
Thank you everyone

If your app is not associated with the extension of the file which is double-clicked, your app will not be launched...

Yeah , i know that , this is the reason I'm going to set my software as a default app for some extensions and also i will check the extension of the file that the user try to open with my software

Answer 2

To get the opened file name from the Windows, use Environment.GetCommandLineArgs method. The Environment.GetCommandLineArgs method returns a string array containing the command-line arguments for the current process. The first element is the executable file name.

To read file content, you could use System.IO.File.ReadAllText method:

string FilePath = string.Join(" ", Environment.GetCommandLineArgs().Skip(1).ToArray());  
if (!string.IsNullOrEmpty(FilePath))  
{  
   string FileContent = System.IO.File.ReadAllText(FilePath);  
   Console.WriteLine(FileContent);  
}

To play a file using your application, add a MediaElement control to your WPF Window using Designer. In XAML you will have something like '<MediaElement x:Name="mediaElement1" />'. To start playing a file, execute this line:

mediaElement1.Source = new Uri( @"C:\MyFiles\SomeAudioFile.wma");
