2018-6-8隨筆-combox繫結-語音-刪空格

1.下面介紹三種對comboBox繫結的方式，分別是泛型中IList和Dictionary，還有資料集DataTable ----->>>>>飛機票

2. 簡單的語音播報系統

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 語音功能1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        SpeechSynthesizer voice = new SpeechSynthesizer();   //建立語音例項

        private void Form1_Load(object sender, EventArgs e)

        {

            voice.Rate = -; //設定語速,[-10,10]

            voice.Volume = ; //設定音量,[0,100]

           // voice.SpeakAsync("Hellow Word");  //播放指定的字串,這是非同步朗讀

            //下面的程式碼為一些SpeechSynthesizer的屬性，看實際情況是否需要使用

            //voice.Dispose();  //釋放所有語音資源

          // voice.SpeakAsyncCancelAll();  //取消朗讀

            voice.Speak("你好！ Word");  //同步朗讀

            //voice.Pause();  //暫停朗讀

           // voice.Resume(); //繼續朗讀

        }

        private void button1_Click(object sender, EventArgs e)

        {

            voice.Speak(textBox1.Text);

        }

        private void button2_Click(object sender, EventArgs e)

        {

            voice.Pause();  //暫停朗讀

        }

        private void button3_Click(object sender, EventArgs e)

        {

             voice.Resume(); //繼續朗讀

        }

    }

}

需要新增引用：引用--新增引用--.NET--Speech引用新增即可；

暫停說明：不會像播放器一樣，點選暫停立即暫停，會播放完當前的語音，下次播放則不能正常播放

繼續播放：在暫停後需要點選，這樣才會正常的播放

可以每次播放完，釋放語音資源，這樣會減少效能消耗。 釋放是把當前物件釋放了，下次播放要重新例項物件

切記不能死迴圈播放，這個不能立即停止，所有這樣記憶體會一直佔用的。

    public partial class Form2 : Form

    {

        public Form2()

        {

            InitializeComponent();

        }

        SpeechSynthesizer speech;

        private void button2_Click(object sender, EventArgs e)

        {

            try

                {

                     speech = new SpeechSynthesizer();

                    //同步朗讀文字

                    //speech.Speak(richTextBox1.Text);

                    //非同步朗讀文字

                    speech.SpeakAsync(textBox1.Text);

                    speech.Volume = ;     //設定音量

                    speech.Rate =-;    //設定朗讀速度

                    //輸出檔案

                  //  speech.SetOutputToWaveFile(CheckPathTruth(textBox2.Text.Trim()));//輸出語言檔案

                }

                catch (Exception ex)

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

            }

        private void button3_Click(object sender, EventArgs e)

        {

            if (button3.Text == "暫停")

            {

                speech.Pause();//暫停

                button3.Text = "繼續";

            }

            else if (button3.Text == "繼續")

            {

                speech.Resume();//繼續

                button3.Text = "暫停";

            }

        }

        private void button4_Click(object sender, EventArgs e)

        {

            //停止朗讀

            speech.SpeakAsyncCancelAll();

            //釋放資源！

            speech.Dispose();

        }

        }

    }

上面是我下午寫的，發現：非同步朗讀文字可以用暫停、繼續、停止功能，同步朗讀是不能的，想好好理解的，可以看看非同步同步問題；

上面可以去除vs中的多餘空格非常實用的哈
