问题描述

我如何在C＃识别中将sqlserver表转换为语法？

例如：

how i do convert a sqlserver table to grammar in C# recognition ?
for example:

var db = new DataClasses1DataContext();
        var word = from c in db.Englishes select c;
                   comboBox1.DataSource = word;
         comboBox1.DisplayMember = "English_Word";
           comboBox1.ValueMember = "English_Word";

           string[]  conv=new string[100000];

           for (int a = 0; a < comboBox1.Items.Count; a++)  conv[a] = comboBox1.Items[a].ToString();
           Choices comands = new Choices();
           comands.Add(conv);
           GrammarBuilder gbuilder = new GrammarBuilder();
           gbuilder.Append(comands);
           Grammar grammar = new Grammar(gbuilder);

           recEngine.LoadGrammarAsync(grammar);
           recEngine.SetInputToDefaultAudioDevice();
           recEngine.RecognizeAsync(RecognizeMode.Multiple); //Error here

错误

recEngine.RecognizeAsync（RecognizeMode.Multiple）;

（{在识别之前必须加载至少一个语法。}）是错误

请帮助我谢谢你

is error in

recEngine.RecognizeAsync(RecognizeMode.Multiple);

( {"At least one grammar must be loaded before doing a recognition."} ) is error

please help me thank you

推荐答案

使用 LoadGrammar 而不是 LoadGrammarAsync 。
如果将其加载为异步，则只在加载完成后启动识别器。添加 LoadGrammarCompleted 事件处理程序，启动识别器：

Load the grammar synchronously, using LoadGrammar instead of LoadGrammarAsync.
If you load it async, only start the recognizer once the loading is complete. Add a LoadGrammarCompleted event handler which starts the recognizer:

recEngine.LoadGrammarCompleted += delegate(EventHandler<LoadGrammarCompletedEventArgs> e)
{
    recEngine.SetInputToDefaultAudioDevice();
    recEngine.RecognizeAsync(RecognizeMode.Multiple);
};
recEngine.LoadGrammarAsync(grammar);
