.NET3.0+中使软件发出声音[整理篇]

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:system.speech.synthesis.speechsynthesizer.pause.aspx

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

官网连接:http://msdn.microsoft.com/zh-cn/library/ms229685(VS.80).aspx

如何查看系统DLL的方法及如何在C#调用它们点我

这里有一个他人封装好的类,见注释

            name = name.Trim();

        }
    }

    public class APIClass
    {
        [DllImport( "kernel32.dll", CharSet = CharSet.Auto )]
        public static extern int GetShortPathName(
         string lpszLongPath,
         string shortFile,
         int cchBuffer
        );

        [DllImport( "winmm.dll", EntryPoint = "mciSendString", CharSet = CharSet.Auto )]
        public static extern int mciSendString(
         string lpstrCommand,
         string lpstrReturnString,
         int uReturnLength,
         int hwndCallback
        );
    }
    #endregion
}

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 );
        }
