本文详细介绍了使用CodeSmith进行代码生成的过程，包括选择合适的模板引擎、解决License限制问题及反编译示例代码等内容。
这一个星期都在与代码生成器在奋战。
一开始，打算采用T4模板引挚。经过两天研究，发现困难很大。T4的设计，是与IDE绑在一起，而且每个visual studio版本，绑定越来越紧，越来越不兼容。
所以，还是打算采用CodeSmith.
一年多没用CodeSmith(原来也不会用)，好不容易找到安装包还有一个重要的示例：
Code Generator using CodeSmith Api
http://www.codeproject.com/Articles/17065/Code-Generator-using-CodeSmith-Api
这个示例，比较清楚地写出了如何调用CodeSmith API，通过模板，生成代码：
但是，这个作者比较小气，没有公开原码。我也不清楚为什么，可能也有自己的原因。
所以，我反编译过了，找到了代码：

compiler.Compile();然而，意想不到的事情发生了。
没想到CodeSmith公司，更是小气，CodeSmith.Engine.dll 竞然，需要license才可以被调用，我了个去，有这么黑的吗？
原来用的是4.1.1，然后到网上，找了一天多，终于找到5.3有破解的CodeSmith.Engine.dll库。

Code Smith v5.3.3 破解补丁
真是救了我的工作啊。
感谢上帝。
否则，我可能就得自己亲自动手来破解了。可能又得几天。
另外，我的代码里，有两处注掉了，如果你已有数据库，想让界面每次弹出，都事先写好信息，就把那些代码反注掉：
第一处：
public CodeGenerator()
{
this.InitializeComponent();
this.GetServerName();
this.comboBox1.SelectedIndex = 1;
//如果不想每次都输入用户密码，就打开这些注释
//tbUserid.Text = "sa";
//tbPwd.Text = "123456"; //haoyujie
}
第二处：
private void CodeGenerator_Load(object sender, EventArgs e)
{
this.properties = new GenericPropertyCollection_CustomTypeDescriptor();
this.properties.AddProperty(new GenericProperty("NameSpace", "PIMail", "NameSpace", "This is the NameSpace of the project", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("Entire DataBase", "True", "DataBase", "Is Code generated for whole database or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeDelete", "True", "StoreProcedure Options", "Is Delete StoreProcedure Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeDrop", "True", "StoreProcedure Options", "Is Drop Script Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeInsert", "True", "StoreProcedure Options", "Is Insert Script Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeUpdate", "True", "StoreProcedure Options", "Is Update Script Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeGet", "True", "StoreProcedure Options", "Is Get Script Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("IncludeGetList", "True", "StoreProcedure Options", "Is GetList Script Included or not", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("DeletePrefix", "Delete", "StoreProcedure Style", "the prefix for delete store procedure", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("InsertPrefix", "Add", "StoreProcedure Style", "the prefix for Add store procedure", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("SelectPrefix", "Select", "StoreProcedure Style", "the prefix for Select store procedure", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("UpdatePrefix", "Update", "StoreProcedure Style", "the prefix for Update store procedure", new Attribute[0]));
this.properties.AddProperty(new GenericProperty("DotNet Version", "2003", "Version", "The DotNet Version ", new Attribute[0]));
this.propertyGrid1.SelectedObject = this.properties;
this.propertyGrid1.Refresh();
//如果不想每次都输入用户密码，就打开这些注释
//haoyujie
// this.GetConnection();
// string curDatabaseName = "AutoPack";
//this.dbName.SelectedText = curDatabaseName;
// if (!this.Added) //标记属性框里，是否有
// {
// AddDatabaseName(curDatabaseName);
// }
// else
// {

// }
// this.dbName.SelectedIndex = 0;
// this.dbtoolStripComboBox2.SelectedIndex = this.dbName.SelectedIndex;
// this.rbDatabase.Checked = false;

// tbName.SelectedItem = "TBL_TREE_HIERARCHY";
// //////////////////////////////////////////////////////////////////////////

}
这是我反编译后的代码，边窗体都做好了。方便大家学习。
如果有人认为我冒犯了他的权益，就联系我。
等了半天，还没出天，哪天出来，我把链接放在这里。

另外，请优快云的编辑们放心，我所反编译的代码，原作者是提供原码的。
只是现在找不到原码了。所以，我这也不算什么过分。
