Exemples

L’exemple de code suivant illustre l’utilisation du CodeCommentStatement(String, Boolean) constructeur pour créer une instruction de commentaire à utiliser comme champ de commentaire XML. Cet exemple fait partie d’un exemple plus large qui suit.

// Declare a new code entry point method.
CodeEntryPointMethod start = new CodeEntryPointMethod();
start.Comments.Add(new CodeCommentStatement("<summary>", true));
start.Comments.Add(new CodeCommentStatement(
    "Main method for HelloWorld application.", true));
start.Comments.Add(new CodeCommentStatement(
    @"<para>Add a new paragraph to the description.</para>", true));
start.Comments.Add(new CodeCommentStatement("</summary>", true));

' Declare a new code entry point method.
Dim start As New CodeEntryPointMethod()
start.Comments.Add(New CodeCommentStatement("<summary>", True))
start.Comments.Add(New CodeCommentStatement( _
    "Main method for HelloWorld application.", True))
start.Comments.Add(New CodeCommentStatement( _
    "<para>Add a new paragraph to the description.</para>", True))
start.Comments.Add(New CodeCommentStatement("</summary>", True))

Remarques

Si le docComment paramètre est true, est CodeCommentStatement un commentaire de documentation et le commentaire est structuré à l’aide de caractères délimiteurs triples. Par exemple, en C#, le commentaire est «/// », en Visual Basic «''' ». Les commentaires de documentation sont utilisés pour identifier un champ de commentaire XML, tel qu’un type ou un résumé de membre identifié par l’élément <summary> .
