We then on a continued, on the one described in ConfigSection structure and two simple DEMO, Benpian said about SectionGroup, ConfigurationElementCollection and key / value pair configurationsection.
usage of.
1, SectionGroup use
The following code simply explain the use SectionGroup:
1), first define a class that inherits ConfigurationSectionGroup:
1: /// <summary>
2: /// Custom SectionGroup
3: /// </summary>
4: public class MySectionGroup:ConfigurationSectionGroup
5: {
6: [ConfigurationProperty("myBlog")]
7: public MySection MyBlog
8: {
9: get
10: {
11: return (MySection)base.Sections["myBlog"];
12: }
13: }
14: }
2), followed by a succession of Section ConfigurationSection in the definition:
1: /// <summary>
2: /// Custom Section
3: /// </summary>
4: public class MySection:ConfigurationSection
5: {
6: [ConfigurationProperty("name")]
7: public string Name Blog
8: {
9: get
10: {
11: return (string)base["name"];
12: }
13: }
14: [ConfigurationProperty("url")]
15: public string BlogUrl
16: {
17: get
18: {
19: return (string)base["url"];
20: }
21: }
22: }
The following talk more about how to use and how to configure in web.config:
web.config configuration:
1: <configSections>
2: <sectionGroup name="myBlogs" type="KevinDiao.MySectionDemo01.MySectionGroup,KevinDiao.MySectionDemo01">
3: <section name="myBlog" type="KevinDiao.MySectionDemo01.MySection,KevinDiao.MySectionDemo01"/>
4: </sectionGroup>
5: </configSections>
6:
7: <myBlogs>
8: <myBlog name="五香瓜子" url="http://www.cnblogs.com/diaojia/"></myBlog>
9: </myBlogs>
Read web.config configuration:
1: MySection mySection = ConfigurationManager.GetSection("myBlogs/myBlog") as MySection;
2: Response.Write ( "blog name:" mySection.BlogName + + "a");
3: Response.Write("博客地址：<a href='" + mySection.BlogUrl + "'>" + mySection.BlogUrl + "</a>");
Run the results obtained:
Blog name: Spiced seeds
Blog address: HTTP: //www.cnblogs.com/diaojia/
2, ConfigurationElementCollection use
Here again discuss how to configure custom collection in ConfigSections, we still use the code illustrate.
1), first define a class inherit ConfigurationElement.
1: /// <summary>
2: /// Custom Element
3: /// </summary>
4: public class MyBlogElement:ConfigurationElement
5: {
6: [ConfigurationProperty("name")]
7: public string Name
8: {
9: get
10: {
11: return (string)base["name"];
12: }
13: }
14: [ConfigurationProperty("url")]
15: public string Url
16: {
17: get
18: {
19: return (string)base["url"];
20: }
21: }
22: }
It consists primarily of the main content you want to configure.
2), followed by the definition of a class that inherits ConfigurationElementCollection
1: /// <summary>
2: /// Custom ElementCollection
3: /// </summary>
4: public class MyBlogElementCollection:ConfigurationElementCollection
5: {
6: protected override ConfigurationElement CreateNewElement()
7: {
8: return new MyBlogElement();
9: }
10: protected override object GetElementKey(ConfigurationElement element)
11: {
12: return ((MyBlogElement)element).Name;
13: }
14: public override ConfigurationElementCollectionType CollectionType
15: {
16: get
17: {
18: return ConfigurationElementCollectionType.BasicMap;
19: }
20: }
21:
22: protected override string ElementName
23: {
24: get
25: {
26: return "myBlog";
27: }
28: }
29: public MyBlogElement this[int index]
30: {
31: get
32: {
33: return (MyBlogElement)BaseGet(index);
34: }
35: set
36: {
37: if (BaseGet(index) != null)
38: {
39: BaseRemoveAt (index);
40: }
41: BaseAdd(index, this);
42: }
43: }
44: }
3) once again define a class that inherits ConfigurationSection
1: /// <summary>
2: /// Custom Section
3: /// </summary>
4: public class MyBlogSection:ConfigurationSection
5: {
6: [ConfigurationProperty("name")]
7: public string Name
8: {
9: get
10: {
11: return (string)base["name"];
12: }
13: }
14: [ConfigurationProperty("",IsDefaultCollection=true)]
15: public MyBlogElementCollection MyBlogCollection
16: {
17: get
18: {
19: return (MyBlogElementCollection)base[""];
20: }
21: }
22:
23: }
Here a look at how how to configure in web.config:
1: <configSections>
2: <section name ="MyBlogs" type="KevinDiao.MySectionDemo02.MyBlogSection,KevinDiao.MySectionDemo02"/>
3: </configSections>
4: <MyBlogs name="KevinDiao">
5: <myBlog name="五香瓜子" url="http://www.cnblogs.com/diaojia/"></myBlog>
6: <myBlog name="业精于勤" url="http://diaojia.blog.51cto.com/"></myBlog>
7: </MyBlogs>
Look at how read:
1: MyBlogSection mySection = ConfigurationManager.GetSection("MyBlogs") as MyBlogSection;
2: foreach (MyBlogElement item in mySection.MyBlogCollection)
3: {
. 4: Response.Write ( "blog name:" item.name + + "a");
5: Response.Write("博客地址：<a href='" + item.Url + "'>" + item.Url + "</a>" + "<br/>");
6: Response.Write("-----------------------------------------------------------------<br/>");
7: }
Finally, look at the results of the operation:
Blog name: Spiced seeds
Blog address: HTTP: //www.cnblogs.com/diaojia/
-----------------------------------------------------------------
Blog name: diligence
Blog address: HTTP: //diaojia.blog.51cto.com/
-----------------------------------------------------------------
3, key / value pair configurationsection used (e.g.: appSettings)
Finally, explain how to use a simple key / value pair configurationsection in web.config.
1), first define a class inherit ConfigurationElement
1: /// <summary>
2: /// custom ConfigurationElement
3: /// </summary>
4: public class MyBlogElement: ConfigurationElement
5: {
6: [ConfigurationProperty("name")]
7: public string Name
8: {
9: get
10: {
11: return (string)base["name"];
12: }
13: }
14: [ConfigurationProperty("url")]
15: public string Url
16: {
17: get
18: {
19: return (string)base["url"];
20: }
21: }
22: }
In fact, and in 2, ConfigurationElementCollection of the same.
2), followed by a succession of ConfigurationElementCollection class definition:
1: /// <summary>
2: /// Custom ConfigurationElementCollection
3: /// </summary>
4: public class MyBlogsElectionCollection:ConfigurationElementCollection
5: {
6: protected override ConfigurationElement CreateNewElement()
7: {
8: return new MyBlogElement();
9: }
10:
11: protected override object GetElementKey(ConfigurationElement element)
12: {
13: return ((MyBlogElement)element).Name;
14: }
15: }
3), again it is the definition of a class that inherits ConfigurationSection
1: /// <summary>
2: /// Custom Section
3: /// </summary>
4: public class MyBlogsSection : ConfigurationSection
5: {
6: [ConfigurationProperty("name")]
7: public string Name
8: {
9: get
10: {
11: return (string)base["name"];
12: }
13: }
14: [ConfigurationProperty("",IsDefaultCollection=true)]
15: public MyBlogsElectionCollection MyBlogs
16: {
17: get
18: {
19: return (MyBlogsElectionCollection)base[""];
20: }
21: }
22: }
Here a look at how how to configure in web.config:
1: <configSections>
2: <section name="MyBlogs" type="KevinDiao.MySectionDemo03.MyBlogsSection,KevinDiao.MySectionDemo03"/>
3: </configSections>
4: <MyBlogs name="KevinDiao">
5: <add name="五香瓜子" url="http://www.cnblogs.com/diaojia/"></add>
6: <add name="业精于勤" url="http://diaojia.blog.51cto.com/"></add>
7: </MyBlogs>
Look at how read:
1: MyBlogsSection mySection = ConfigurationManager.GetSection("MyBlogs") as MyBlogsSection;
2: foreach (MyBlogElement item in mySection.MyBlogs)
3: {
. 4: Response.Write ( "blog name:" item.name + + "a");
5: Response.Write("博客地址：<a href='" + item.Url + "'>" + item.Url + "</a>" + "<br/>");
6: Response.Write("-----------------------------------------------------------------<br/>");
7: }
Finally, look at the results of the operation:
Blog name: Spiced seeds
Blog address: HTTP: //www.cnblogs.com/diaojia/
-----------------------------------------------------------------
Blog name: diligence
Blog address: HTTP: //diaojia.blog.51cto.com/
-----------------------------------------------------------------
