C# 使用自定义xml标记设置App.Config

目前，在正确设置时存在一些问题。我在web上对此做了大量阅读，并尝试了使用不同代码的多种配置，但对于以下自定义xml标记，我似乎无法使其正常工作。有人能就如何解决这个问题提供一些反馈吗？我想从其他类外部访问它，并遍历每个“trackInfo”标记以查找某个键。最后一段代码是我试图提取元素并将其保存为变量的地方

我正在寻找的东西： -我错过了什么？ -我如何在课外学习

App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="trackLog" type="Tracking.TrackConfigSection,   Tracking" />
  </configSections>

  <trackLog>
    <trackInfo key="DEV1" env="dev1" url="http://dev1.com" />
    <trackInfo key="DEV2" env="dev2" url="http://dev2.com" />
  </trackLog>
</configuration>

TrackConfigCollection.cs

[ConfigurationCollection(typeof(TrackConfigEntry), CollectionType = ConfigurationElementCollectionType.BasicMap)] 
        public class TrackConfigCollection : ConfigurationElementCollection
        {
            const string ItemName = "trackInfo";

            public override ConfigurationElementCollectionType CollectionType
            {
                get 
                { 
                    return ConfigurationElementCollectionType.BasicMap; 
                }
            }

            protected override object GetElementKey(ConfigurationElement element)
            {
                return ((TrackConfigEntry)element).Key;
            }

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

            public new TrackConfigEntry this[string key]
            {
                get 
                { 
                    return (TrackConfigEntry)BaseGet(key); 
                }
            }

            public bool Contains(string role)
            {
                return BaseGetAllKeys().Contains(role);
            }

        }

TrackConfigEntry.cs

public class TrackConfigSection : ConfigurationSection
{
    private const string SectionName = "trackLog";

    public TrackConfigSection()
    {
        base[""] = new TrackConfigCollection();
    }

    [ConfigurationProperty("", IsRequired = true, IsKey = false, IsDefaultCollection = true)]
    public TrackConfigCollection TrackConfigs
    {
                get { return ((TrackConfigCollection)(base[""])); }
                set { base[""] = value; }
    }

    public static TrackConfigCollection GetTrackConfigs()
    {
        return ((TrackConfigSection)ConfigurationManager.GetSection(SectionName)).TrackConfigs;
    }
}

public class TrackConfigEntry : ConfigurationElement
{
    [ConfigurationProperty("key", IsRequired = true)]
    public string Key 
    { 
        get { return (string)base["key"]; } 
    }

    [ConfigurationProperty("env", IsRequired = true)]
    public string env 
    { 
        get { return (string)base["env"]; } 
    }

    [ConfigurationProperty("url", IsRequired = true)]
    public string url 
    { 
        get { return (string)base["url"]; } 
    }
}

var envName = System.Configuration.ConfigurationManager.AppSettings["env"];
// the envName is in the tags in the app.config
if (TrackConfigSection.GetTrackConfigs().Contains(envStringName))
{
string temp1 = TrackConfigSection.GetTrackConfig("key").ToString(); // variable to get key
                    string temp2 = TrackConfigSection.GetTrackConfig("env").ToString(); // variable to get env
                    string temp3 = TrackConfigSection.GetTrackConfig("url").ToString(); // variable to get url
}

从其他类访问

public class TrackConfigSection : ConfigurationSection
{
    private const string SectionName = "trackLog";

    public TrackConfigSection()
    {
        base[""] = new TrackConfigCollection();
    }

    [ConfigurationProperty("", IsRequired = true, IsKey = false, IsDefaultCollection = true)]
    public TrackConfigCollection TrackConfigs
    {
                get { return ((TrackConfigCollection)(base[""])); }
                set { base[""] = value; }
    }

    public static TrackConfigCollection GetTrackConfigs()
    {
        return ((TrackConfigSection)ConfigurationManager.GetSection(SectionName)).TrackConfigs;
    }
}

public class TrackConfigEntry : ConfigurationElement
{
    [ConfigurationProperty("key", IsRequired = true)]
    public string Key 
    { 
        get { return (string)base["key"]; } 
    }

    [ConfigurationProperty("env", IsRequired = true)]
    public string env 
    { 
        get { return (string)base["env"]; } 
    }

    [ConfigurationProperty("url", IsRequired = true)]
    public string url 
    { 
        get { return (string)base["url"]; } 
    }
}

var envName = System.Configuration.ConfigurationManager.AppSettings["env"];
// the envName is in the tags in the app.config
if (TrackConfigSection.GetTrackConfigs().Contains(envStringName))
{
string temp1 = TrackConfigSection.GetTrackConfig("key").ToString(); // variable to get key
                    string temp2 = TrackConfigSection.GetTrackConfig("env").ToString(); // variable to get env
                    string temp3 = TrackConfigSection.GetTrackConfig("url").ToString(); // variable to get url
}

除了@wal关于在configSection中修复程序集名称的评论之外。您还应该重写

TrackConfigCollection

类中的

ElementName

属性。将以下内容添加到

TrackConfigCollection

类中：

protected override string ElementName
{
    get { return ItemName; }
}

有关自定义配置的更多信息，请参阅优秀文章

编辑

var key = "DEV1"; 
if(TrackConfigSection.GetTrackConfigs().Contains(key))
{
    var config = TrackConfigSection.GetTrackConfigs()[key];
    var env = config.env;
    var url = config.url;
}

类型正确吗？这似乎不是一个正确的程序集/类型名称模式。您是指“我有一个“跟踪”名称空间，其他类使用它吗？是正确的程序集名称吗？即，不是

type=“Tracking.TrackConfigSection，TrackConfigSection”

而是

type=“Tracking.TrackConfigSection，name\u of\u程序集“

其中程序集的名称是

TrackConfigSection

所在的程序集，该程序集的末尾没有.dll，但仍然无法工作？你有什么例外吗？没错，它仍然不起作用，我问题末尾的那段代码看起来有效吗？对我来说似乎有效。来自我的示例的代码：var env=“DEV1”；var config=TrackConfigSection.GetTrackConfigs（）.Contains（env）；是的，if语句是有效的，但是我如何提取带有key=“DEV1”的标记的“env”和“url”？（如要使用的正确函数）
