Příklady

Následující příklad kódu ukazuje použití konstruktoru CodeCommentStatement(String, Boolean) k vytvoření příkazu komentáře, který se použije jako pole komentáře XML. Tento příklad je součástí většího příkladu, který následuje.

// 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))

Následující příklad kódu ukazuje vytvoření jednoduché konzolové aplikace "Hello World" a generování souboru dokumentace XML pro zkompilovanou aplikaci.

Poznámky

docComment Pokud je trueparametr , CodeCommentStatement je komentář dokumentace a komentář je strukturován pomocí tří znaků oddělovače. Například v jazyce C# je komentář "///", v jazyce Visual Basic "'''". Komentáře k dokumentaci se používají k identifikaci pole komentáře XML, jako je typ nebo souhrn členů identifikovaný elementem <summary> .
