Hello, I need to implement the following scenario:

I want to create several files using a list of parameters retrieved from a wizard.
The problem is that i don´t know how many files i need to create, this depends on the input in the wizard.
So i need to call the same action (actually 2 actions, one to create the string with all the class code and another to insert the file in a project) several times accordingly to the number of objects in a collection retrieved from the wizard. I investigated and found several ways to achieve this goal:

Declaratively:
1 - Using a ForEach tag in the action configuration. But i didn´t find any complete example of this. Is it possible to do something like this?

<Action Name="GenerateClasses"
Type="TextTemplateAction"
Template="Text\Standard.t4"
ForEach="$(DataContractsList)"
CurrentInputName="DataContractInfo"
<Input Name="TableEntityInfo"/>
<Output Name="Content" />
</Action>

Programmatically
2 - Using an Action that receives the wizard info and calling the t4 action internally - This has a known problem related to passing arguments programmatically to a T4 template. Can anyone tell how to pass arguments from inside an Action to a T4 Action?

3 - Using directlyITextTemplatingEngine like:

string tempfile = Path.GetTempFileName();

TypeResolutionService typeResService = (TypeResolutionService)GetService(typeof(ITypeResolutionService));
Dictionary<string, PropertyData> dict = new Dictionary<string, PropertyData>();
dict.Add("ClassName", new PropertyData(modulo, typeof(string)));
host.TemplateFile = @"C:\Documents and Settings\Computer\Project\Templates\Text\Template.cs.t4";
TemplateHost host = new TemplateHost(Directory.GetCurrentDirectory(), dict);


ITextTemplatingEngine engine = new Engine();
string template = File.ReadAllText(host.TemplateFile);
stringTemplateText = engine.ProcessTemplate(template, host);

using (StreamWriter sw = new StreamWriter(tempfile, false))
{
sw.WriteLine(TemplateText);
}
EnvDTE.ProjectItem item = CreateDirectoryPresenter();
item.ProjectItems.AddFromTemplate(tempfile, "");
File.Delete(tempfile);

This last one seem the more complicated way.


Please... What is the best way to call several times a T4 Action with different parameter values?


Thank You

One approach that Iuse is to create a custom Action class thatderivesfromMicrosoft.Practices.RecipeFramework.VisualStudio.Library.Templates.T4Action. In doing so, I can iterate through an object and then render a template for each item in that object. It's not too messy, and this approach also allows be to combine the template rendering and the creation of the artifact file into a single action. Below is code that demonstrates my basic approach:
