Examples

The following code example demonstrates the use of the CodeCommentStatement(String, Boolean) constructor to create a comment statement to be used as an XML comment field. This example is part of a larger example that follows.

C#

// 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));

The following code example demonstrates the creation of a simple "Hello World" console application and the generation of an XML documentation file for the compiled application.

C#

using System.CodeDom;
using System.CodeDom.Compiler;
using System.IO;
using System.Text.RegularExpressions;

            LogMessage("Building CodeDOM graph...");

            CodeCompileUnit cu = new CodeCompileUnit();

            cu = BuildHelloWorldGraph();

            StreamWriter sourceFile = new StreamWriter(sourceFileName);
            provider.GenerateCodeFromCompileUnit(cu, sourceFile, null);
            sourceFile.Close();

            CompilerParameters opt = new CompilerParameters(new string[]{
                                      "System.dll" });

Remarks

If the docComment parameter is true, the CodeCommentStatement is a documentation comment and the comment is structured using triple delimiter characters. For example, in C# the comment is "///", in Visual Basic "'''". Documentation comments are used to identify an XML comment field, such as a type or member summary identified by the <summary> element.
