网上的资料大多数是使用DirectX实现

在运行的时候只要form类里面有这个类名出现就不显示窗体也不报错误。求大神解答



 private void button1_Click(object sender, EventArgs e)

        {

            try

            {

                MessageBox.Show("开始录音！");

                SoundRecord record = new SoundRecord();

                record.mWavFormat = record.SetWaveFormat();

                record.CreateCaputerDevice();

                record.CreateCaptureBuffer();

                record.CreateWaveFile(@"E:\test.wav");

                record.CreateNotification();

                record.capturebuffer.Start(true);

                Thread.Sleep(10000);

                //record.StopRec();

                MessageBox.Show("录音结束！");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

        }

上面类名SoundRecord 在事件里触发事件的时候就没反映了

如果类名直接在类里面即使未实例化窗体都不显示



        private SoundRecord record = null;

        private void button1_Click(object sender, EventArgs e)

        {

            try

            {

                MessageBox.Show("开始录音！");

                record = new SoundRecord();

                record.mWavFormat = record.SetWaveFormat();

                record.CreateCaputerDevice();

                record.CreateCaptureBuffer();

                record.CreateWaveFile(@"E:\test.wav");

                record.CreateNotification();

                record.capturebuffer.Start(true);

                Thread.Sleep(10000);

                //record.StopRec();

                MessageBox.Show("录音结束！");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

        }
