第一种方法:Speech

Speech控件在.NET中使用非常简单了,都被封装好了

官方连接:

分三步,第一步添加引用(.NET3.0+ SDK中自带)

using System.Speech.Synthesis

第二步,初始化设置

Talker.Rate = -2;Talker.Volume = 100;Talker.SelectVoiceByHints( VoiceGender.Male, VoiceAge.Child, 2, System.Globalization.CultureInfo.CurrentCulture );

第三步,直接朗读文本

Talker.SpeakAsync( "Hello world!" );

第二种方法:System.Media.SoundPlayer

这个更简单,一步即可

private void playSound(string path)        {            System.Media.SoundPlayer player =                new System.Media.SoundPlayer();            player.SoundLocation = path;            player.Load();            player.Play();        }

这个简单是简单了些,功能也简单了,仅支持标准的wav格式

第三种方法:调用平台DLL,winmm.dll

这里有一个他人封装好的类,见注释

第四种:由第三种引申,使主板发出声音

[DllImport( "kernel32.dll" )]        private static extern int Beep( int dwFreq, int dwDuration );        void _Beep() {            System.Random r = new Random();            for( int i = 0 ; i < 100 ; i++ ) {                int c = r.Next( 10000 );                Beep( c, 100 );            }            Beep( 2047, 200 );        }
