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 (ruleEuroperuleSAmerica) ,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 (winnerRuleruleEuroperuleSAmerica) 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 SrgsRuleSrgsRuleRefSrgsOneOfSrgsItem
