備註
使用類別的函 SrgsDocument 式,您可以從 SrgsDocument GrammarBuilder SrgsRule 包含 XML 格式文法路徑的字串,建立、或物件的實例, XmlReader 或者您可以起始空白的實例 SrgsDocument 。
SrgsDocument()

public:
SrgsDocument();
public SrgsDocument ();
Public Sub New ()
範例
下列範例會建立 SrgsDocument 物件,然後建立名為的公用規則 winnerRule
。 然後,它會建立 SrgsItem ,其中包含「已贏得世界盃的全國是:」字串,並將此專案新增至規則的 Elements 屬性。 然後,此範例會建立兩個規則 (ruleEurope
和 ruleSAmerica
) ,其中每個都是 SrgsOneOf 包含三個物件的物件 SrgsItem 。 之後, SrgsOneOf 會建立另一個物件,其中包含 SrgsRuleRef 參考和的 ruleEurope
物件 ruleSAmerica
。 新 SrgsOneOf 物件接著會加入的 Elements 屬性 winnerRule
。 之後,所有三個規則 (winnerRule
、 ruleEurope
和 ruleSAmerica
) 都會加入的屬性中 Rules SrgsDocument 。 最後,這三個規則會編譯成文法的二進位標記法。
public void WorldSoccerWinners ()
{
// Create an SrgsDocument, create a new rule
// and set its scope to public.
SrgsDocument document = new SrgsDocument();
SrgsRule winnerRule = new SrgsRule("WorldCupWinner");
winnerRule.Scope = SrgsRuleScope.Public;
// Add the introduction.
winnerRule.Elements.Add(new SrgsItem("A nation that has won the World Cup is: "));
// Create the rule for the European nations.
SrgsOneOf oneOfEurope = new SrgsOneOf(new SrgsItem[] {new SrgsItem("England"),
new SrgsItem("France"), new SrgsItem("Germany"), new SrgsItem("Italy")});
SrgsRule ruleEurope = (new SrgsRule("EuropeanNations", new SrgsElement[] {oneOfEurope}));
// Create the rule for the South American nations.
SrgsOneOf oneOfSAmerica = new SrgsOneOf(new SrgsItem[] {new SrgsItem("Argentina"),
new SrgsItem("Brazil"), new SrgsItem("Uruguay")});
SrgsRule ruleSAmerica = (new SrgsRule("SouthAmericanNations", new SrgsElement[] {oneOfSAmerica}));
// Add references to winnerRule for ruleEurope and ruleSAmerica.
winnerRule.Elements.Add(new SrgsOneOf(new SrgsItem[] {(new SrgsItem
(new SrgsRuleRef(ruleEurope))), new SrgsItem(new SrgsRuleRef(ruleSAmerica))}));
// Add all the rules to the document and make winnerRule
// the root rule of the document.
document.Rules.Add(new SrgsRule[] {winnerRule, ruleEurope, ruleSAmerica});
document.Root = winnerRule;
String fileName = Path.GetTempFileName();
using (FileStream stream = new FileStream(fileName, FileMode.Create))
{
// Compile the grammar to a binary format.
SrgsGrammarCompiler.Compile(document, stream);
}
}
備註
這個函式會建立空的 SrgsDocument 實例。 若要在空白實例內建立文法 SrgsDocument ,請新增代表 SRGS 元素的類別實例,例如 SrgsRule 、 SrgsRuleRef 、 SrgsOneOf 和 SrgsItem 。
適用於
SrgsDocument(GrammarBuilder)

- GrammarBuilder
GrammarBuilder 物件,用於建立 SrgsDocument 執行個體。
例外狀況

。
範例
下列範例會使用物件,在實例中建立文法 GrammarBuilder Choices 。 然後,它會 SrgsDocument 從 GrammarBuilder 物件建立。
GrammarBuilder builder = null;
// Create new Choices objects and add countries/regions, and create GrammarBuilder objects.
Choices choicesEurope = new Choices(new string[] { "England", "France", "Germany", "Italy" });
GrammarBuilder europe = new GrammarBuilder(choicesEurope);
Choices choicesSAmerica = new Choices(new string[] { "Argentina", "Brazil", "Uruguay" });
GrammarBuilder sAmerica = new GrammarBuilder(choicesSAmerica);
Choices worldCupWinnerChoices = new Choices(new GrammarBuilder[] {choicesEurope, choicesSAmerica});
// Create new GrammarBuilder from a Choices object.
builder = new GrammarBuilder(worldCupWinnerChoices);
// Create an SrgsDocument object from a GrammarBuilder object.
SrgsDocument document = new SrgsDocument(builder);
適用於
SrgsDocument(SrgsRule)

範例
下列範例會建立兩個規則 chooseCities

) 選擇航班的來源和目的地城市。 此範例會 SrgsDocument 使用 chooseCities
規則做為引數來初始化實例。 此範例會將規則集合的內容和根規則的名稱寫入主控台。
// Create a rule that contains a list of destination cities.
SrgsRule destCities = new SrgsRule("Destination");
SrgsOneOf toCities = new SrgsOneOf(new string[] { "New York", "Seattle", "Denver" });
destCities.Add(toCities);
// Create a list of origin cities and supporting phrases.
SrgsOneOf fromCities = new SrgsOneOf(new SrgsItem[] {
new SrgsItem("Dallas"), new SrgsItem("Miami"), new SrgsItem("Chicago") });
SrgsItem intro = new SrgsItem("I want to fly from");
SrgsItem to = new SrgsItem("to");
// Create the root rule of the grammar, and assemble the components.
SrgsRule chooseCities = new SrgsRule("Trip");
chooseCities.Add(intro);
chooseCities.Add(fromCities);
chooseCities.Add(to);
chooseCities.Add(new SrgsRuleRef(destCities));
// Create the SrgsDocument and specify the root rule to add.
SrgsDocument bookFlight = new SrgsDocument(chooseCities);
// Add the rule for the destination cities to the document's rule collection.
bookFlight.Rules.Add(new SrgsRule[] { destCities });
// Display the contents of the Rules collection and the name of the root rule.
foreach (SrgsRule rule in bookFlight.Rules)
{
Console.WriteLine("Rule " + rule.Id + " is in the rules collection");
}
Console.WriteLine("Root Rule " + bookFlight.Root.Id);
// Create a Grammar object and load it to the recognizer.
Grammar g = new Grammar(bookFlight);
g.Name = ("City Chooser");
recognizer.LoadGrammarAsync(g);
備註
這個函式會將指定的規則加入至物件的, SrgsRulesCollection SrgsDocument 並將它設定為 Root 文法的規則。

document = new SrgsDocument(srgsDocumentFile);
適用於
