Web.config中configSections详细说明

第一部分：Web.config如何定义configSections

建立Test.Demo1类库，默认情况下，此类库的默认属性中，程序集名称为：Test.Demo1,默认命名空间为:Test.Demo1.

此类库生成的Dll相应的为Test.Demo1.dll和Test.Demo1.pdb.

Demo02.cs

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Configuration;namespace Test.SectionDemo{    /// <summary>      /// 自定义Section      /// </summary>      public class SectionHandle : ConfigurationSection    {        [ConfigurationProperty("users", IsRequired = true)]        public SectionElement Users        {            get            {                return (SectionElement)this["users"];            }        }    }}

 

Web.config

<?xml version="1.0"?><!--  有关如何配置 ASP.NET 应用程序的详细信息，请访问  http://go.microsoft.com/fwlink/?LinkId=169433  --><configuration><configSections><section name="SectionHandle" type="Test.SectionDemo.SectionHandle,Test.Demo1"/></configSections><SectionHandle><users username="kevin" password="123"></users></SectionHandle><system.web><compilation debug="true" targetFramework="4.0"/></system.web></configuration>

此处，type=“Test.SectionDemo.SectionHandle"来自Demo2.cs的类定义。和默认命名空间没有关系。

但是Test.Demo1就来自“程序集名称为：Test.Demo1”

Element.cs

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Configuration;namespace Test.SectionDemo{    ///  <summary>        /// 自定义Element      /// </summary>      public class SectionElement : ConfigurationElement    {        /// <summary>          /// 用户名                     /// </summary>                    [ConfigurationProperty("username", IsRequired = true)]        public string UserName        {            get            {                return (string)this["username"];            }        }        ///  <summary>            ///   密码           ///  </summary>            [ConfigurationProperty("password", IsRequired = true)]        public string Password        {            get            {                return (string)this["password"];            }        }    }}

Default.aspx.cs

using System;   using System.Collections.Generic;   using System.Linq;   using System.Web;   using System.Web.UI;   using System.Web.UI.WebControls;        using System.Configuration;using Test.SectionDemo;public partial class _Default : System.Web.UI.Page{    protected void Page_Load(object sender, EventArgs e)    {        SectionHandle mySectionHandle = (SectionHandle)ConfigurationManager.GetSection("SectionHandle");        Response.Write("username：" + mySectionHandle.Users.UserName + "<br/>");        Response.Write("password：" + mySectionHandle.Users.Password + "<br/>");    }}

运行结果

第二部分：assembly小修改

如果将程序集名称手动改为Test.Demo15,默认命名空间也改为Test.Demo15

此时可以看到Bin中的生成文件变了(Test.Demo15.dll)，和程序集名称保持一致。

那么Web.config中也要相应的改为

<section name="SectionHandle" type="Test.SectionDemo.SectionHandle,Test.Demo15"/>

类名称没有变，只是assembly改变了。默认命名空间改动看上去没有影响。
