How to combine multiple sound buffer in real-time with C#?

[trajan]

Sample project:
User write to music note in textbox and push "Play"...

Process begin:
Parse music note (it does not matter)
e.g.
 re re mi mi do re mi (textbox)

SFML.Audio.SoundBuffer SndBf_re = new SoundBuffer(soundLocation + "re.wav");
SFML.Audio.SoundBuffer SndBf_mi = new SoundBuffer(soundLocation + "mi.wav");
SFML.Audio.SoundBuffer SndBf_do = new SoundBuffer(soundLocation + "do.wav");
 

How to:

SFML.Audio.Sound UserNote = new Sound(SndBf_re+SndBf_re+SndBf_mi+SndBf_mi+SndBf_do+SndBf_re+SndBf_mi);
UserNote.Play();
 

Process ended

sorry my bad English.

I'm not sure if anyone gets what the heck you want to do/where the problem is...
There are tutorials and examples on how to use SFML if it's just about the basics.

Concatenate the sample arrays of eacy sound buffer into a new bigger sound buffer. But that's only if you want to save the combined music. If you just want to play it, then simply play one sound buffer after the other.

Thank you everyone, following code nicely working -need little corrections-.

string soundLocation = AppDomain.CurrentDomain.BaseDirectory + "notes\\";

int totalAddedLen = 0;
Int16[] newBigMusic = new Int16[10000000];

public Form1()
{
      InitializeComponent();
      LoadAndPlay();
}

private void tryProductBuffer(Int16[] Buff)
{
      Array.Copy(Buff, 0, newBigMusic, totalAddedLen, Buff.Length);
      totalAddedLen = totalAddedLen + Buff.Length;
}

public void LoadAndPlay()
{
      SoundBuffer do_a = new SoundBuffer(soundLocation + "do_a.wav");
      SoundBuffer re = new SoundBuffer(soundLocation + "re.wav");
      SoundBuffer mi = new SoundBuffer(soundLocation + "mi.wav");
      SoundBuffer fa = new SoundBuffer(soundLocation + "fa.wav");
      SoundBuffer sol = new SoundBuffer(soundLocation + "sol.wav");
      SoundBuffer la = new SoundBuffer(soundLocation + "la.wav");
      SoundBuffer si = new SoundBuffer(soundLocation + "si.wav");
      SoundBuffer do_b = new SoundBuffer(soundLocation + "do_b.wav");
           
      /*
            User enter textbox -> do do re re do re mi
            string[0]->
            if(do_a)
            {
                  tryProductBuffer(do_a.Samples);
            }
            if(re)
            {
                  tryProductBuffer(re.Samples);
            }
             ...
      */
     
      Array.Resize(ref newBigMusic, totalAddedLen);
      SoundBuffer AllBuf = new SoundBuffer(newBigMusic, 2, 44100);
      AllBuf.SaveToFile("newBigMusic.wav");
      Sound Q = new Sound(AllBuf);
      // Q.Pitch = 3;
      Q.Play();
}
