Why? Do you have any new ideas? Are you familiar with several best-known popular players? Do you have an idea for something better? If you do, why didn't you share it with us. If you don't want to share it, I don't know why would you need help. If not, I don't know why would you want to write one. Just to practice? But practice on what, if you, as I can understand, want to use available components. To say people "this is my own player"? Clever people won't be impressed by just that...

I'm not here to create any new ideas or to impress anyone, I just wanted a way to play sound files for my project.

This isn't a question suitable for this forum, please see the FAQ[^].

Apart from that, as a programmer, you should know about Google - these are the first two results I got by googling "c# mp3 player":

I found a way to do it, first I had to upgrade to visual studio 2012, so I could use Net framework 4.5, then I used MediaPlayer from the namespace System.Windows.Media to play my sound files, look specifically at m_BGSM_Play_Click for the code that plays the sound files.

C#

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Windows.Media;

namespace RPGInventor
{
    public partial class MapProperties : Form
    {
        CMap m_Map;
        string m_InitialMapName;
        bool m_bEdit;
        int m_nLayer;
        MediaPlayer m_SoundPlayer;

        public MapProperties()
        {
            InitializeComponent();
            m_bEdit = false;

            m_mapType.Items.Add("Normal");
            m_mapType.Items.Add("World Map");

            m_mapLayer.Items.Add("Layer 1");
            m_mapLayer.Items.Add("Layer 2");
            m_mapLayer.Items.Add("Layer 3");

            m_mapTileType.Items.Add("Normal");
            m_mapTileType.Items.Add("Floor");
            m_mapTileType.Items.Add("Wall");

            m_BGSM_SD.Items.Add("BGM");
            m_BGSM_SD.Items.Add("BGS");
            m_BGSM_SD.Items.Add("ME");
            m_BGSM_SD.Items.Add("SE");

            m_BI_SD.Items.Add("BGM");
            m_BI_SD.Items.Add("BGS");
            m_BI_SD.Items.Add("ME");
            m_BI_SD.Items.Add("SE");

            m_SoundPlayer = new MediaPlayer();
            //m_SoundPlayer.MediaEnded += m_SoundPlayer_MediaEnded;
        }

        //void m_SoundPlayer_MediaEnded(object sender, EventArgs e)
        //{
            //m_SoundPlayer.Position = new TimeSpan(0, 0, 0);
            //m_SoundPlayer.Play();
        //}

        public MapProperties(CMap map)
        {
            InitializeComponent();
            m_Map = map;
            m_bEdit = false;

            m_mapType.Items.Add("Normal");
