Contoh

Contoh kode berikut menunjukkan penggunaan konstruktor CodeCommentStatement(String, Boolean) untuk membuat pernyataan komentar yang akan digunakan sebagai bidang komentar XML. Contoh ini adalah bagian dari contoh yang lebih besar yang mengikuti.

// 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))

Contoh kode berikut menunjukkan pembuatan aplikasi konsol "Halo Dunia" sederhana dan pembuatan file dokumentasi XML untuk aplikasi yang dikompilasi.

Keterangan

Jika parameter docCommenttrue, CodeCommentStatement adalah komentar dokumentasi dan komentar disusun menggunakan karakter pembatas tiga kali lipat. Misalnya, di C# komentarnya adalah "///", di Visual Basic "'''". Komentar dokumentasi digunakan untuk mengidentifikasi bidang komentar XML, seperti jenis atau ringkasan anggota yang diidentifikasi oleh elemen <summary>.
