Enterprise Library Step By Step系列（二）：配置应用程序块——进阶篇
以下讲解4.1与2.0的不同
首先我们来看自定义数据类
1
using System.Text;
2using System.Configuration;

4namespace ConfigurationMigrationQuickStart
5
{
6
/// <summary>
7
/// Summary description for ConfigurationData.
8
/// </summary>
9 public class EditorFontData : ConfigurationSection
10 {
11
12 public EditorFontData()
13 {
14 }
15
16 [ConfigurationProperty("name")]
17 public string Name
18 {
19 get { return (string)this["name"]; }
20 set{ this["name"] = value; }
21 }
22
23 [ConfigurationProperty("size")]
24 public float Size
25 {
26 get{ return (float)this["size"]; }
27 set{ this["size"] = value; }
28 }
29
30 [ConfigurationProperty("style")]
31 public int Style
32 {
33 get { return (int)this["style"]; }
34 set{ this["style"] = value; }
35 }
36
37 public override string ToString()
38 {
39 StringBuilder sb = new StringBuilder();
40 sb.AppendFormat("Name = {0}; Size = {1}; Style = {2}", Name, Size.ToString(), Style.ToString());
41
42 return sb.ToString();
43 }
44 }
45
}

{26

}29
30
[ConfigurationProperty("style")]31
public int Style 32
{33

set{ this["style"] = value; }35
} 36
37
public override string ToString() 38
{39
StringBuilder sb = new StringBuilder();40
sb.AppendFormat("Name = {0}; Size = {1}; Style = {2}", Name, Size.ToString(), Style.ToString());41
42
return sb.ToString();43
}44
}45
}46
用属性(Attribution)来标记了对应的属性(Property)
如[ConfigurationProperty("name")]
下面结合App.config来看
App.config
可见，每个属性(Attribute)都对应着XML节点的属性
与2.0不同的是，4.1中好像没法用用Enterprise Library Configuration配置应用程序
以下是配置的详细步骤：
先建立一个项目，
然后建立自定义配置数据类，
在App.config或Web.config中添加节点<configSections>
在<configSections>节点下添加你自定义的节点的信息如：
<configSections>
<section name="EditorSettings" type="ConsoleApplication1.EditorFontData, ConsoleApplication1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null" />
</configSections>
然后添加你自定义的节点
在工程中添加引用System.Configureation，如图所示：
读的代码：
写的代码：
清除缓存的代码：
<section name="EditorSettings" type="ConsoleApplication1.EditorFontData, ConsoleApplication1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null" />
</configSections>
然后添加你自定义的节点
在工程中添加引用System.Configureation，如图所示：
读的代码：
EditorFontData configData = ConfigurationManager.GetSection("EditorSettings") as EditorFontData;
写的代码：
// Write the new configuration data to the XML file
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.Sections.Remove("EditorSettings");
config.Sections.Add("EditorSettings", configData);
config.Save();
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.Sections.Remove("EditorSettings");
config.Sections.Add("EditorSettings", configData);
config.Save();
清除缓存的代码：
ConfigurationManager.RefreshSection("EditorSettings");
