Introduction

DotNetNuke (DNN), a beautiful web portal application,It do very good job of sloving the problerm of base web application pluming. Module Development is a primary and important work if you want to create a individuation website DNNModule.Template is a template that is based upon SmartCode.You can create the dotnetnuke module code quickly,it include DataProvide,SqlDataprovider,ModuleInfo and controller.

Background

I had learned DNN two years ago,Developte some Modules.When I find SmartCode from Codeproject,I decide to build a SmartCode Template to use to create dotnetnuke module basecode quickly.

Using the code

the following code just for create "SqlDataProvider":

           using System;
using System.Collections.Generic;
using System.Text;
using SmartCode.Template;
using SmartCode.Model;
namespace DNNModule.Template
{
     public  class SqlDataProvider:TemplateBase 
    {
         public SqlDataProvider()
        {
            this.createFile = true;
            this.description = "";
            this.name = "Providers.DataProviders.SqlDataProvider";
            this.outputFolder = @"Components/Providers/DataProviders/SqlDataProvider";
        }
        public override string OutputFileName()
        {
            return Table.Name + "SqlDataProvider.cs";
        }

        public override void ProduceCode()
        {
            WriteLine("using System; ");
