Hello i want to show options like "Add to Queue" or "Add to Playlist >" when user right clicks an .mp3 file.
How can i do that with C# and winforms?
What you’re describing is known as a "context menu". And you can’t do it directly in C#. It’s run from the Windows registry, which you can edit from C#, but you usually need to ask the user permission.
This should get you started:
C# adding context menu item to windows explorer for all file types
