GrammarBuilder.Implicit 运算符

public:
 static operator System::Speech::Recognition::GrammarBuilder ^(System::Speech::Recognition::Choices ^ choices);

public static implicit operator System.Speech.Recognition.GrammarBuilder (System.Speech.Recognition.Choices choices);

static member op_Implicit : System.Speech.Recognition.Choices -> System.Speech.Recognition.GrammarBuilder

Public Shared Widening Operator CType (choices As Choices) As GrammarBuilder

参数

返回

GrammarBuilder

转换的 Choices 对象。

示例

下面的示例创建一个语音识别语法，它可以识别对 "是" 或 "否" 问题的响应。 隐式转换运算符用于 SemanticResultValue 从对象构造对象 Choices 、 Choices 从两个对象构造对象 SemanticResultValue ，以及在对象的构造 Grammar 对象 SemanticResultKey 中构造对象。

Choices yesChoices = new Choices(new string[] {"yes", "yup", "yah"});  
SemanticResultValue yesValue =  
  new SemanticResultValue(yesChoices, true);  

Choices noChoices = new Choices(new string[] { "no", "nope", "nah" });  
SemanticResultValue noValue =  
  new SemanticResultValue(noChoices, false);  

SemanticResultKey yesnoKey =  
  new SemanticResultKey("yesno", new Choices(new GrammarBuilder[] { yesValue, noValue }));  

Grammar yesnoGrammar = new Grammar(yesnoKey);  
yesnoGrammar.Name = "yesno";  

注解

隐式转换创建的一个新实例 GrammarBuilder 。 此转换运算符等效于调用 GrammarBuilder 并为指定 choices alternateChoices 。

此运算符的等效方法是 GrammarBuilder.GrammarBuilder(Choices)

• GrammarBuilder()

public:
 static operator System::Speech::Recognition::GrammarBuilder ^(System::String ^ phrase);

public static implicit operator System.Speech.Recognition.GrammarBuilder (string phrase);

static member op_Implicit : string -> System.Speech.Recognition.GrammarBuilder

Public Shared Widening Operator CType (phrase As String) As GrammarBuilder

参数

返回

GrammarBuilder

已转换的字符串。

示例

下面的示例使用 GrammarBuilder 和 Choices 对象来构造语法，该语法可识别两个短语中的任意一个： "使背景 colorChoice" 或 "将背景设置为 colorChoice"。

使用对象为 colorChoice 创建可接受的值列表后 Choices ，该示例将 GrammarBuilder makePhrase setPhrase 使用字符串对象的隐式转换初始化两个对象。

该示例最终 Grammar 从 Choices 对象强制转换为对象创建对象 GrammarBuilder 。

private Grammar CreateColorGrammar()  
{  

  // Create a set of color choices.  
  Choices colorChoice = new Choices(new string[] {"red", "green", "blue"});  
  GrammarBuilder colorElement = new GrammarBuilder(colorChoice);  

  // Create grammar builders for the two versions of the phrase.  
  GrammarBuilder makePhrase = new GrammarBuilder("Make background");  
  makePhrase.Append(colorElement);  
  GrammarBuilder setPhrase = new GrammarBuilder("Set background to");  
  setPhrase.Append(colorElement);  

  // Create a Choices for the two alternative phrases, convert the Choices  
  // to a GrammarBuilder, and construct the Grammar object from the result.  
  Choices bothChoices = new Choices(new GrammarBuilder[] {makePhrase, setPhrase});  
  Grammar grammar = new Grammar((GrammarBuilder)bothChoices);  
  grammar.Name = "backgroundColor";  
  return grammar;  
}  

注解

隐式转换创建的一个新实例 GrammarBuilder 。 此转换运算符等效于调用 GrammarBuilder 并指定相同的 phrase 。

此运算符的等效方法是 GrammarBuilder.GrammarBuilder(String)
