2018-6-8随笔-combox绑定-语音-删空格

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;
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。

                }
                catch (Exception ex)
                {  MessageBox.Show(ex.Message);    return;   }

            }

        private void button3_Click(object sender, EventArgs e)
        {
            if (button3.Text == "暂停")
            {
                speech.Pause();//暂停
                button3.Text = "继续";
            }

            else if (button3.Text == "继续")
            {
                speech.Resume();//继续
                button3.Text = "暂停";
            }
        }

        private void button4_Click(object sender, EventArgs e)
        {
            //停止朗读
            speech.SpeakAsyncCancelAll();
            //释放资源！
            speech.Dispose();

        }

        }
    }

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
