录音我一般更喜欢mci方式，当然也有另一种方式及DirectSound不过它会麻烦许多

但是它却有一个让我感到较好的特点，首先可以选择录音设备源，第二它不像mci

必须要写到本地磁盘，它是把录制音频流存放在内存中，在速度上我认为它会快很

多，不过它也有一个缺点让我不舒服，它不如mci哪样是默认集成在系统中的，我这

个人特喜欢使用系统自带的函数，主要你不需要去拷贝DLL因为系统是默认就有的，

只需要去调用就行了，方便 当然mci提供的操作命令我比较讨厌mciSendCommand

原因在于我自己得写一大堆结构体 是让我感到非常讨厌的，mciSendString则是通过

字符串，属于轻量操作函数我倒是喜欢的紧。

        private SoundRecord m_Record = new SoundRecord();          private void MainForm_Load(object sender, EventArgs e)          {                   this.m_Record.OpenRecord(); // 打开录音              this.m_Record.StartRecord(); // 开始录音          }            private void BtnStopAndSave_Click(object sender, EventArgs e)          {                         this.m_Record.StopRecord(); // 停止录音              this.m_Record.SaveRecord(@"C:\Users\windo\Desktop\1.wav"); // 保存录音              this.m_Record.CloseRecord(); // 关闭录音          }

上面的代码只是一个简单的录音并保存的过程，不过该类本身就很简单 而且我也附

有注释，想必你们应该不会感到学习困难，录音属性配置默认初始化在构造函数中。
