IConfigurationSectionHandler 接口

IConfigurationSectionHandler

处理对特定的配置节的访问。

示例代码：

  public class MyConfig : IConfigurationSectionHandler

    {

        public int MyNum1 { get; set; }

        public int MyNum2 { get; set; }

        public int MyNum3 { get; set; }

        public MyConfig()

        {

            MyNum1 = ;

            MyNum2 = ;

            MyNum3 = ;

        }

        // implement interface member

        public object Create(object parent, object configContext, System.Xml.XmlNode section)

        {

            try

            {

                MyConfig options = new MyConfig();

                if (section == null) return options;

                foreach (XmlNode node in section.ChildNodes)

                {

                    if (node.Name == "MyNum1")

                        options.MyNum1 = int.Parse(node.InnerText);

                    else if (node.Name == "MyNum2")

                        options.MyNum2 = int.Parse(node.InnerText);

                    else if (node.Name == "MyNum3")

                        options.MyNum3 = int.Parse(node.InnerText);

                }

                return options;

            }

            catch (Exception ex)

            {

                throw new Exception(ex.Message);

            }

        }

    }

Web.config配置：

<section name="MyConfig" type="WebApp.MyConfig" />

及

 <MyConfig>

    <MyNum1>111</MyNum1>

    <MyNum2>222</MyNum2>

    <MyNum3>333</MyNum3>

  </MyConfig>

<configSections>

    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

    <section name="MyConfig" type="WebApp.MyConfig" />

  </configSections>

  <MyConfig>

    <MyNum1></MyNum1>

    <MyNum2></MyNum2>

    <MyNum3></MyNum3>

  </MyConfig>

调用：

 var myconfig = WebConfigurationManager.GetSection("MyConfig") as MyConfig;

            Response.Write(myconfig.MyNum2);
