NAUDIO.dll C# event handler issue

[Superposed_Cat]

This is one of the many code samples I've tried for NAUDIO,but on all of them they say that += new EventHandler<StoppedEventArgs> is incorrect. There is no other issue. Anybody know what's happening?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using NAudio;
using System.Windows.Forms;
using NAudio.Wave;
using NAudio.Utils;
using NAudio.Mixer;
using NAudio.Midi;

using System.Timers;

namespace WindowsFormsApplication4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

       
         public WaveIn waveSource = null;
    public WaveFileWriter waveFile = null;
    public string RECORDING_PATH;

    public void AudioRecorder(string fileName)
    {
        RECORDING_PATH = fileName;
    }

    public void Start()
    {
        waveSource = new WaveIn();
        waveSource.WaveFormat = new WaveFormat(44100, 1);
        waveSource.DeviceNumber = 0;
        waveSource.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);
        waveSource.RecordingStopped += new EventHandler<StoppedEventArgs>(waveSource_RecordingStopped);

        waveFile = new WaveFileWriter(RECORDING_PATH, waveSource.WaveFormat);

        System.Timers.Timer t = new System.Timers.Timer(30000);

        t.Elapsed += new ElapsedEventHandler(Stop);

        waveSource.StartRecording();

        t.Start();


    }

    private void Stop(object sender, ElapsedEventArgs args)
    {
        waveSource.StopRecording();
    }

    private void waveSource_DataAvailable(object sender, WaveInEventArgs e)
    {
        if (waveFile != null)
        {
            waveFile.WriteData(e.Buffer, 0, e.BytesRecorded);
            waveFile.Flush();
        }
    }

    private void waveSource_RecordingStopped(object sender, StoppedEventArgs e)
    {
        if (waveSource != null)
        {
            waveSource.Dispose();
            waveSource = null;
        }

        if (waveFile != null)
        {
            waveFile.Dispose();
            waveFile = null;
        }

    }
    }
}

You aren't coding this as a console application, are you?

Some more information would be helpful, such as the version of NAudio you're using, and a detailed description of the error you're seeing.

Are you getting this error at runtime or compile time? It compiles fine for me.

I think I just had an incompatible version because I referenced the DLL from one of my other projects and it works fine. Thanks anyways, apologies for the inconveniance.

I would first suggest checking for any typos or syntax errors in the code. It is also important to make sure that all necessary libraries and dependencies are properly imported and referenced.

Additionally, it may be helpful to consult the documentation for NAUDIO and see if there are any specific requirements or steps that need to be followed in order to properly use the event handler. It is also possible that there may be a bug or issue with the NAUDIO library itself, in which case contacting the developers or seeking assistance from other users may be helpful.

In general, troubleshooting code issues can be a complex and iterative process, so it may require some trial and error to identify and resolve the issue. It may also be helpful to break down the code into smaller sections and test each one individually to pinpoint where the issue is occurring.
