将自己的configSection添加到App.Config [英] Adding own configSection to App.Config

问题描述

您好。

我尝试在App.Config中添加部分。

I tried to add section in App.Config.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="workers" type="MyProject.Setup.Config.WorkerElement, MyProject" />
  </configSections>
  <workers>
    <worker name="Name" type="Operator" />
  </workers>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1" />
  </startup>
</configuration>

课程：

public class WorkersConfigSection : ConfigurationSection
    {
        [ConfigurationProperty("workers")]
        public WorkersCollection WorkersCollection
        {
            get => ((WorkersCollection) base["workers"]);
            set => base["workers"] = value;
        }
    }

[ConfigurationCollection(typeof(WorkerElement), AddItemName = "worker")]
    public class WorkersCollection : ConfigurationElementCollection
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new WorkerElement();
        }

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


public class WorkerElement : ConfigurationElement
    {
        [ConfigurationProperty("name", IsKey = true, IsRequired = true)]
        public string Name
        {
            get => (string)base["name"];
            set => base["name"] = value;
        }

        [ConfigurationProperty("type", IsKey = false, IsRequired = true)]
        public WorkerType Type
        {
            get => (WorkerType)base["type"];
            set => base["type"] = value;
        }
    }

但是在调试时我捕获异常类型 'MyProject.Setup.Config.WorkerElement'未实现'System.Configuration.IConfigurationSectionHandler'。

But on debug I catch exception Type 'MyProject.Setup.Config.WorkerElement' does not implement 'System.Configuration.IConfigurationSectionHandler'.

我哪里弄错了？

请请参考以下代码示例并修改您的应用程序。

Hi  fadeinmad,  

>>But on debug I catch exception Type 'MyProject.Setup.Config.WorkerElement' does not implement 'System.Configuration.IConfigurationSectionHandler'.

Please refer the following code sample and modify your application.

 <configSections>
    <section name="WorkersConfigSection" type="WpfApp_temp2.WorkersConfigSection, WpfApp_temp2" />
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2" />
  </startup>
  <WorkersConfigSection>
    <workers>
      <worker name="Name" type="Operator" />
      <worker name="Name2" type="Operator2"></worker>
    </workers>
  </WorkersConfigSection>

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            var connectionManagerDataSection = ConfigurationManager.GetSection(WorkersConfigSection.SectionName) as WorkersConfigSection;
            if (connectionManagerDataSection != null)
            {
                foreach (WorkerElement endpointElement in connectionManagerDataSection.WorkersCollection)
                {
                    var endpoint = new WorkerElement() { Name = endpointElement.Name , Type=endpointElement.Type };
                    MessageBox.Show("Name: "+endpoint.Name+"; Type: "+ endpoint.Type);
                }
            }
        }


    public  class WorkersConfigSection : ConfigurationSection
    {

        public const string SectionName = "WorkersConfigSection";

        [ConfigurationProperty("workers")]
        [ConfigurationCollection(typeof(WorkersCollection), AddItemName = "worker")]
        public WorkersCollection WorkersCollection
        {
            get => ((WorkersCollection)base["workers"]);
            set => base["workers"] = value;
        }
    }


    public class WorkersCollection : ConfigurationElementCollection
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new WorkerElement();
        }

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



    public class WorkerElement : ConfigurationElement
    {
        [ConfigurationProperty("name", IsKey = true, IsRequired = true)]
        public string Name
        {
            get => (string)base["name"];
            set => base["name"] = value;
        }

        [ConfigurationProperty("type", IsKey = false, IsRequired = true)]
        public string Type
        {
            get => (string)base["type"];
            set => base["type"] = value;
        }
    }
