Create Your Own MP3 Player with C# and DirectShow Functionality

Creating an Mp3 Player Using C# Windows Form Application and

DirectShow Functionality

Are you a music enthusiast and always wanted to create your MP3 player? Or maybe you’re a code nerd looking for a new project to take on?

Whatever the reason may be, this article will walk you through how to create your MP3 player using both C# Windows Form Application and DirectShow functionality. C# Windows Form Application

Designing the Windows Form

When creating an application, the first step is to design the user interface. In this case, we need a Windows Form to display our MP3 player application.

The design should be simple and user-friendly for an excellent user experience.

Adding Windows Media Player Component

The next step is to drag and drop a Windows Media Player component into the Windows form. The Windows Media Player component will play our MP3 files.

This component provides a lot of useful functionalities that we can use to make our MP3 player more intuitive.

Adding MP3 Files to Your Application

Your MP3 Player won’t play any MP3 files without adding them to the application. We need to use an OpenFileDialog to browse and select the MP3 files.

Once the MP3 files are selected, we will populate a ListBox with their names. We will use a for loop to iterate through the MP3 files in the ListBox and play them when the user clicks on the MP3 file.

This is done using the click event handler.

Playing Audio Files in Windows Media Player

Finally, we use the source code to play our audio files in the Windows Media Player component. Once the user has clicked on a specific MP3 file in the ListBox, the click event will trigger the code to load that file into the Windows Media Player component and play it.

DirectShow Functionality

Creating QuartzTypeLib.dll

DirectShow is a framework provided by Microsoft for capturing and processing audio and video streams on Windows. To use it in our C# project, we need to create a Runtime-Callable Wrapper (RCW) by running the tlbimp tool on the included QuartzTypeLib.idl file.

This will create a type library as a .dll file, which we can add as a reference to our project.

Adding the QuartzTypeLib Reference to Your Project

We can reference any COM component in our project by using the “Add Reference” dialog box in Visual Studio. This will automatically generate an RCW for the component.

While adding the reference to our project, we need to make sure to embed the interop types, enable the “Prefer 32-bit” option, and handle the exceptions thrown at runtime.

Using Source Code to Create an MP3 Windows Form Application

Finally, we use the source code to create an MP3 Windows Form application. We implement the DirectShow framework to play our MP3 files.

We use the MediaControl interface to start and stop the playback, and the IBasicAudio interface to adjust the volume. We also use the IMediaSeeking interface to seek to a specific position in the audio file.


Creating an MP3 player using either C# Windows Form Application or DirectShow functionality can seem like a daunting task, but following the steps outlined above will make it much more manageable. By designing a user-friendly interface, adding the Windows Media Player Component and MP3 files, and using source code, we can create an application that is both engaging and intuitive.

With the DirectShow framework, we can further enhance our application by allowing for more advanced control over the playback and processing of MP3 files. In this article, we have explored how to create an MP3 player using C# Windows Form Application and DirectShow functionality.

We covered the essential steps involved in designing a user-friendly interface, adding the Windows Media Player component, and playing audio files using both methods. By following these steps, you can develop an intuitive MP3 player tailored to your needs.

As we’ve seen, both frameworks offer numerous functionalities capable of advanced control over playback and processing of MP3 files. With the knowledge gained from this article, you can now confidently explore and develop your MP3 player.
