好直接到主題。首先是資料實體messageentry（我到老a的基礎上添加了description屬性作為代碼字段描述）：
1 namespace wolf
2 {
3 public class messageentry
4 {
5 public string id { get; private set; }
6 public string value { get; private set; }
7 public string description { get; private set; }
8 public messageentry(string id, string value)
9 {
10 this.id = id;
11 this.value = value;
12 }
13
14 public messageentry(string id, string value, string description)
15 {
16 this.id = id;
17 this.value = value;
18 this.description = description;
19 }
20
21 public string format(params object[] args)
22 {
23 return string.format(this.value, args);
24 }
25 }
26 }

在我的機子上的codesimth是2..0版本的是以不能使用linq命名空間，我又想利用這個空間，比較快捷，是以我就在先3.0轉化為
dictionary<string, list<messageentry>>實體再傳入模闆：
code：
1 using system;
2 using system.collections.generic;
3 using system.linq;
4 using system.text;
5 using system.xml;
6 using system.xml.linq;
7
8 namespace wolf
9 {
10 public class messagecodegenerator
11 {
12 public dictionary<string, list<messageentry>> generatorcode(string path)
13 {
14 return generatorcode(xelement.load(path));
15 }
16 public dictionary<string, list<messageentry>> generatorcode(xelement root)
17 {
18
19 var elemts = root.elements("message").groupby(e => ((xattribute)e.attribute("category")).value);
20 dictionary<string, list<messageentry>> dict = new dictionary<string, list<messageentry>>();
21 foreach (var item in elemts)
22 {
23 list<messageentry> list = new list<messageentry>();
24 foreach (var g in item)
25 {
26 if (g.attribute("description") != null)
27 {
28 list.add(new messageentry(((xattribute)g.attribute("id")).value, ((xattribute)g.attribute("value")).value, ((xattribute)g.attribute("description")).value));
29 }
30 else
31 {
32 list.add(new messageentry(((xattribute)g.attribute("id")).value, ((xattribute)g.attribute("value")).value));
33 }
34
35 }
36 dict.add(item.key.tostring(), list);
37 }
38 return dict;
39
40 }
41 }
42 }
43
44
這下幾可開始寫模闆了，見下code：
1 <%@ codetemplate language="c#" targetlanguage="text" src="" inherits="" debug="false" description="template description here." %>
2
3 <%@ import namespace="system" %>
4 <%@ import namespace="system.xml" %>
5 <%@ import namespace="system.text" %>
6 <%@ import namespace="system.collections.generic" %>
7 <%@ import namespace="wolf" %>
8 <%@ assembly name="wolf" %>
9
10 <script runat="template">
11
12 private dictionary<string, list<messageentry>> dict;
13 public dictionary<string, list<messageentry>> generator
14 {
15 get
16 {
17 return dict;
18 }
19 set
20 {
21 dict=value;
22 }
23 }
24
25 public string generatorcode()
26 {
27 string str = "using wolf;\r\nusing system;\r\nusing system.collections.generic;\r\nnamespace wolf.message\r\n{ \r\n public class messages\r\n {\r\n";
28 foreach (string catage in generator.keys)
29 {
30 str += " public class "+catage + "\r\n { \r\n";
31 foreach (wolf.messageentry entry in generator[catage])
32 {
33 str += "\r\n /// <summary>" +
34 "\r\n ///" + entry.description +
35 "\r\n /// </summary>" +
36 "\r\n public static wolf.messageentry " + entry.id + " = new messageentry(\"" + entry.id + "\", \"" + entry.value +"\", \"" + entry.value +"\");\r\n";
37 }
38 str += "\r\n }\r\n\r\n";
40 }
41 str += "\r\n }\r\n}";
42 return str;
43 }
45 </script>

47 <%= generatorcode()%>

很簡單，就不說了，如果有問題請留言，其中命名空間完全可以以屬性方式傳入。
xml實體用的是老a的：
代碼
1 <?xml version="1.0" encoding="utf-8" ?>
2 <messages>
3 <message id="mandatoryfield" value="the {0} is mandatory." category="validation" description="description" />
4 <message id="greaterthan" value="the {0} must be greater than {1}." category="validation" description="description" />
5 <message id="reallydelete" value="do you really want to delete the {0}." category="confirmation" description="description" />
6 </messages>

我想脫離codesimth工具，是以在建立了一個控制台程式，引用codesmith.engine.dll程式集。
1 static void main(string[] args)
2 {
3 // wolf.message.messages.confirmation.reallydelete.value
4 // test();
5 codetemplate template = compiletemplate(@"e:\myapp\linqtest\consoleapplication1\messagecodegenerator.cst",s=>console.writeline(s));
6 if (template != null)
7 {
8 template.setproperty("_messagefilepath", "");
9 wolf.messagecodegenerator gen = new messagecodegenerator();
10 dictionary<string, list<messageentry>> dict = gen.generatorcode(@"e:\myapp\linqtest\consoleapplication1\sample.xml");
11 template.setproperty("generator", dict);
12 template.rendertofile("gen.cs", true);
13 // system.diagnostics.process.start("gen.cs");
14 }
15 // console.read();
16
17 }
19 public static codetemplate compiletemplate(string templatename,action<string> errorwriter)
20 {
21 codetemplatecompiler compiler = new codetemplatecompiler(templatename);
22 compiler.compile();
23
24 if (compiler.errors.count == 0)
25 {
26 return compiler.createinstance();
27 }
28 else
29 {
30 for (int i = 0; i < compiler.errors.count; i++)
31 {
32 errorwriter(compiler.errors[i].tostring());
33 }
34 return null;
35 }
36
37 }
38
生成後的代碼：
1 //copyright (c) wolf. all rights reserved.
2 using wolf;
3 using system;
4 using system.collections.generic;
5 namespace wolf.message
6 {
7 public class messages
8 {
9 public class validation
10 {
12 /// <summary>
13 ///description
14 /// </summary>
15 public static wolf.messageentry mandatoryfield = new messageentry("mandatoryfield",
17 "the {0} is mandatory.", "the {0} is mandatory.");
19 /// <summary>
20 ///description
21 /// </summary>
22 public static wolf.messageentry greaterthan = new messageentry("greaterthan",
24 "the {0} must be greater than {1}.", "the {0} must be greater than {1}.");
25
26 }
28 public class confirmation
29 {
30
31 /// <summary>
32 ///description
33 /// </summary>
34 public static wolf.messageentry reallydelete = new messageentry("reallydelete",
35
36 "do you really want to delete the {0}.", "do you really want to delete the {0}.");
37
38 }
40 }
41 }
