C# App.Config自定义配置节问题

我已经为我的应用程序创建了一个自定义配置部分。由于某些原因，VisualStudio2010无法获取和更新我的自定义属性。我收到的警告与所有“添加”键类似：

配置文件：

<configSections>
    <section name="urlFilterSection" type="BotFinderApp.Models.UrlFilterSection, BotFinder" />
</configSections>

<urlFilterSection>
    <urlFilterCollection>
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
        <add url="urlhere.com.au" numberOfIpsToExtract="10" />
    </urlFilterCollection>
</urlFilterSection>

namespace BotFinderApp.Models
{
    public class UrlFilterSection : ConfigurationSection
    {
        public UrlFilterSection()
        {    
        }

        [ConfigurationProperty("urlFilterCollection", IsDefaultCollection = false)]
        [ConfigurationCollection(typeof(UrlFilterCollection), AddItemName = "add", ClearItemsName = "clear", RemoveItemName = "remove")]
        public UrlFilterCollection Urls
        {
            get
            {
                var urlsCollection = (UrlFilterCollection)base["urlFilterCollection"];
                return urlsCollection;
            }
        }
    }
}

UrlFilterCollection

namespace BotFinderApp.Models
{
    public class UrlFilterCollection : ConfigurationElementCollection
    {
        public UrlFilterCollection()
        {
        }

        protected override ConfigurationElement CreateNewElement()
        {
            return new UrlFilter();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((UrlFilter)element).Url;
        }
    }
}

UrlFilter

namespace BotFinderApp.Models
{
    public class UrlFilter : ConfigurationElement
    {
        public UrlFilter()
        {
        }

        [ConfigurationProperty("url", DefaultValue = "", IsRequired = true)]
        public string Url
        {
            get { return (string)this["url"]; }
            set { this["url"] = value; }
        }

        [ConfigurationProperty("numberOfIpsToExtract", DefaultValue = "0", IsRequired = true)]
        public int NumberOfIpsToExtract
        {
            get { return (int)this["numberOfIpsToExtract"]; }
            set { this["numberOfIpsToExtract"] = value; }
        }
    }
}

发现问题：

Decyclone是正确的，错误实际上只是编译时警告

真正的问题是，我是这样访问我的配置的：

UrlFilterCollection serviceConfigSection = ConfigurationManager.GetSection("urlFilterSection") as UrlFilterCollection;

本来应该是这样的

UrlFilterSection serviceConfigSection = ConfigurationManager.GetSection("urlFilterSection") as UrlFilterSection;

谢谢FlipScript和Decyclone:）

更新：

我发现了如何删除编译时警告-我正在使用Visual Studio 2010。创建自定义配置节后，我使用工具栏上的“创建架构”按钮，该按钮生成配置的架构文件。然后我将其保存到我的项目中，警告消失。

您能在应用程序中使用它吗？我的意思是，它只是编译时警告，还是您甚至不能在应用程序中使用它？UrlFilterCollection serviceConfigSection=ConfigurationManager.GetSection（“urlFilterSection”）作为UrlFilterCollection；返回空值。。。

UrlFilterSection serviceConfigSection = ConfigurationManager.GetSection("urlFilterSection") as UrlFilterSection;
