1.下面介绍三种对comboBox绑定的方式，分别是泛型中IList和Dictionary，还有数据集DataTable ----->>>>>飞机票
2. 简单的语音播报系统

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Speech;
using System.Speech.Synthesis; namespace 语音功能1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
SpeechSynthesizer voice = new SpeechSynthesizer(); //创建语音实例
private void Form1_Load(object sender, EventArgs e)
{ voice.Rate = -; //设置语速,[-10,10]
voice.Volume = ; //设置音量,[0,100]
// voice.SpeakAsync("Hellow Word"); //播放指定的字符串,这是异步朗读 //下面的代码为一些SpeechSynthesizer的属性，看实际情况是否需要使用
//voice.Dispose(); //释放所有语音资源
// voice.SpeakAsyncCancelAll(); //取消朗读
voice.Speak("你好！ Word"); //同步朗读
//voice.Pause(); //暂停朗读
// voice.Resume(); //继续朗读
} private void button1_Click(object sender, EventArgs e)
{ voice.Speak(textBox1.Text); } private void button2_Click(object sender, EventArgs e)
{
voice.Pause(); //暂停朗读
} private void button3_Click(object sender, EventArgs e)
{
voice.Resume(); //继续朗读
}
}
}
需要添加引用：引用--添加引用--.NET--Speech引用 添加即可；
暂停说明：不会像播放器一样，点击暂停立即暂停，会播放完当前的语音，下次播放则不能正常播放
继续播放：在暂停后需要点击，这样才会正常的播放
可以每次播放完，释放语音资源，这样会减少性能消耗。 释放是把当前对象释放了，下次播放要重新实例对象
切记不能死循环播放，这个不能立即停止，所有这样内存会一直占用的。

}
上面是我下午写的，发现：异步朗读文本可以用暂停、继续、停止功能，同步朗读是不能的， 想好好理解的，可以看看异步同步问题；
上面可以去除vs中的多余空格 非常实用的哈
