无法为 web.config 创建自定义部分 [英] Unable to create a custom section for web.config

问题描述

我在 web.config 文件中创建了一个自定义部分，但它无法加载我要管理该部分的自定义类型.

I created a custom section in the web.config file but it isn't able to load my custom type that is going to manage the section.

定义如下:

<configSections>
<section
        name="MembershipProviders"
        type="MyApp.BusinessObjects.MembershipProviderFactory.MembershipProvidersSection"
        allowLocation="true"
        allowDefinition="Everywhere"
      />
</configSections>


namespace MyApp.BusinessObjects
{
    public class MembershipProviderFactory
    {
        internal virtual IMembershipProvider Create()
        {
        }

        public class MembershipProvidersSection : ConfigurationSection
        {
            public class AddElement: ConfigurationElement
            {
                [ConfigurationProperty("name", IsKey  = true, IsRequired = true)]
                public string Name
                {
                    get
                    {
                        return this["name"].ToString();
                    }
                    set
                    {
                        this["name"] = value;
                    }
                }

                [ConfigurationProperty("type", IsRequired = true)]
                public string FullyQualifiedTypeName
                {
                    get
                    {
                        return this["type"].ToString();
                    }
                    set
                    {
                        this["type"] = value;
                    }
                }
            }

            public class AddElementCollection : ConfigurationElementCollection
            {
                protected override ConfigurationElement CreateNewElement()
                {
                    return new AddElement();
                }

                protected override object GetElementKey(ConfigurationElement element)
                {
                    return ((AddElement)element).Name;
                }
            }


            [ConfigurationProperty("currentProvider", IsRequired = false)]
            public string CurrentProvider
            {
                get
                {
                    return this["currentProvider"].ToString();
                }
                set
                {
                    this["currentProvider"] = value;
                }
            }

            [ConfigurationProperty("add", IsRequired = true, IsDefaultCollection = true)]
            public AddElementCollection Instances
            {
                get { return (AddElementCollection)this["add"]; }
                set { this["add"] = value; }
            }
        }
    }
}

我收到一个运行时异常，内容为:

I get a run-time exception that says:

为 MembershipProviders 创建配置节处理程序时出错:无法加载类型MyApp.BusinessObjects.MembershipProviderFactory.MembershipProvidersSection".

更新

我还在配置文件中包含了实际部分，如下所示:

I also included the actual section in the config file as follows:

<MembershipProviders currentProvider ="DefaultMembershipProvider" />

我仍然遇到同样的异常.

I still get the same exception.

推荐答案

您需要将程序集名称指定为 type 属性的一部分:

You need to specify the assembly name as part of the type attribute:

<section
    name="MembershipProviders"
    type="Namespace.TheCustomSection, TheAssemblyNameGoesHere"
    allowLocation="true"
    allowDefinition="Everywhere"
/>

编辑
我没有注意到 MembershipProvidersSection 类是一个嵌套类.
类型名称应为:

EDIT
I didn't notice that the MembershipProvidersSection class is a nested class.
The type name should be:

MyApp.BusinessObjects.MembershipProviderFactory+MembershipProvidersSection
