看nettiers整理出来的开发codesmith模板技术要点

//模板的基础知识

//任何模板都需要的第一句，用来指定模板编辑语言是什么，目标语言是什么：
<%@ CodeTemplate Language="C#" TargetLanguage="T-SQL" Description="Generates a update stored procedure." %>

//接下来写模板需要从外界引入的参数
<%@ Property Name="SourceDatabase" Type="SchemaExplorer.DatabaseSchema" Category="Context" Description="Database" %>

//在模板里面用到了codesmith的函数和方法，需要引入对应的包，一般是
<%@ Assembly Name="SchemaExplorer" %>

<%@ Import Namespace="SchemaExplorer" %>

//所有codesmith函数都在script标签里面定义，包括变量
<script runat="template">
private string _outputDirectory = String.Empty;

</script>

调用用<% %> 括起来，一般有一个主函数来执行整个模板的函数
<%
this.Go();
%>




//一般模板的函数和用法


/// <summary>
/// 拷贝指定文件
/// </summary>
public void SafeCopyFile(string path, string destination)
{
FileInfo file1 = new FileInfo(path);
file1.CopyTo(destination, true);
}

/// <summary>
/// 创建指定目录
/// </summary>
public void SafeCreateDirectory(string path)
{
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}


/// <summary>
/// 根据指定模板生成指定文件
/// </summary>
public void RenderToFile(string templateName, string path, bool overwrite)
{
this._CurrentFileName = path;
this.GetTemplate(templateName).RenderToFile(path, overwrite);
this._counter++;
}


/// <summary>
/// 打开文件目录，[Editor]标签表示调用指定的编辑器；category表示参数所属目录;Descript表示对参数的描述;defaultvalue表示缺省值
CodeTemplateProperty表示该参数是可选还是必须的，CodeTemplatePropertyOption.Optional是可选，CodeTemplatePropertyOption.Required是必

须
/// </summary>
private string _outputDirectory = String.Empty;
[Editor(typeof(System.Windows.Forms.Design.FolderNameEditor), typeof(System.Drawing.Design.UITypeEditor))]
[CodeTemplateProperty(CodeTemplatePropertyOption.Optional)]
[Category("General")]
[Description("The directory to output the results to.")]
[DefaultValue("")]
public string OutputDirectory
{
get
{
if (_outputDirectory.Length == 0)
{
return @"c:/NetTiers/" + (SourceDatabase != null ? SourceDatabase.Name : "Output");
}
else
{
return _outputDirectory;
}
}
set
{
if (value.EndsWith("//")) value = value.Substring(0, value.Length - 1);
_outputDirectory = value;
}
}


//获取当前打开模板所在路径
this.CodeTemplateInfo.DirectoryName


//对于模板，当前打开的模板可以用codeTemplateInfo访问，其他的子模板需要先根据文件名和路径载入，然后编辑模板，最后赋予参数，生成文件。

//设定模板路径

我在网上找了半天，发现codesmith遍历文件夹和拷贝文件夹的函数，我知道能够引入system.io这个包，然后自己写这个函数出来，哪位达人写过这样的函数或者有更好的办法可以发过来共享啊
