Again, there is nothing special about the InitializeComponent method, at least as far as generating the code goes. You'd generate code for it the same you would any other method. MSDN is a good source for info about code generation using the classes in the System.CodeDom namespace, so I'd start there if you have specific questions.
You didn't mention what was happening when you run this code, so I can only guess. With that said, the code you posted looks fine expect for a couple small problems. This line:initComp.Comments.Add(new CodeCommentStatement());
will cause a NullReferenceException. If you just want the comment characters (// in C#), but no comment text, you can pass an empty string to the contsructor of CodeCommentStatement.
Also, this line may cause problems:initComp.ReturnType = new CodeTypeReference("void");If you want to pass a string for the return type, you should give the full name (System.Void in this case). An overload of the constructor takes a Type object, so you could remove any doubt by passing typeof(System.Void).
Here's some code showing how to generate a class with this method (I don't know whether you need a sample or not, but I love writing code, so here goes anyway ;))
// This is what will hold the whole ball
// of wax when we're done
CodeCompileUnit codeUnit = new CodeCompileUnit();
// This is the namespace that will contain
// our class
CodeNamespace ns = new CodeNamespace("WindowsForms.Example");
// And here's the actual class
CodeTypeDeclaration myClass = new CodeTypeDeclaration("MyClass");
// I'm guessing you want to derive from Form
myClass.BaseTypes.Add(typeof(System.Windows.Forms.Form));
myClass.Members.Add(new CodeMemberField(typeof
(System.Windows.Forms.Form), "MyForm"));
// Build the method
/****************************************
* Here's the code you posted
***************************************/
// build our InitializeComponent method
//
CodeMemberMethod initComp = new CodeMemberMethod();
initComp.Name = "InitializeComponent";
initComp.ReturnType = new CodeTypeReference("System.Void"); // Full name
initComp.Attributes = MemberAttributes.Private;
initComp.Comments.Add(new CodeCommentStatement("")); // empty string
initComp.Comments.Add(new CodeCommentStatement("Initialize form controls", false));
// add the statements to the init components method
//
initComp.Statements.Add(
new CodeAssignStatement(
new CodeFieldReferenceExpression(
new CodeThisReferenceExpression(), "MyForm"),
new CodeObjectCreateExpression(
new CodeTypeReference(typeof(System.Windows.Forms.Form).ToString(),
0))));
/************************************
* End posted code section
************************************/
// Add the method to the class...
myClass.Members.Add(initComp);
// the class to the namespace...
ns.Types.Add(myClass);
// and the namespace to the CodeCompileUnit
codeUnit.Namespaces.Add(ns);
// We'll use this to get the code generator
CSharpCodeProvider codeProvider = new CSharpCodeProvider();
ICodeGenerator generator = codeProvider.CreateGenerator();
// This isn't strictly necessary. You can just
// create a new CodeGeneratorOptions object when
// you generate the code and accept the defaults.
// I just happen to not like the openening brace on the
// same line as the declaration
CodeGeneratorOptions options = new CodeGeneratorOptions();
options.BlankLinesBetweenMembers = true;
options.ElseOnClosing = false;
options.BracingStyle = "C";
// This is what we'll write the generated code to
IndentedTextWriter writer = new IndentedTextWriter(new StreamWriter("MyClass.cs"));
// Generate the code, passing the CodeCompileUnit,
// output stream, and generator options
generator.GenerateCodeFromCompileUnit(codeUnit, writer, options);
// clean up
writer.Close();
And here is the contents of MyClass.cs:
