我是 C# 中配置部分的初学者，
我想在配置文件中创建一个自定义部分。谷歌搜索后我尝试过的
配置文件如下： 

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="MyCustomSections">
      <section name="CustomSection" type="CustomSectionTest.CustomSection,CustomSection"/>
    </sectionGroup>
  </configSections>

  <MyCustomSections>
    <CustomSection key="Default"/>
  </MyCustomSections>
</configuration>


CustomSection.cs 

    namespace CustomSectionTest
{
    public class CustomSection : ConfigurationSection
    {
        [ConfigurationProperty("key", DefaultValue="Default", IsRequired = true)]
        [StringValidator(InvalidCharacters = "~!@#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)]
        public String Key
        {
            get { return this["key"].ToString(); }
            set { this["key"] = value; }
        }
    }
}


当我使用此代码检索部分时，我收到一条错误消息，提示配置错误。

var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("CustomSection");


我错过了什么？
谢谢。

编辑
我最终需要的是

    <CustomConfigSettings>
    <Setting id="1">
        <add key="Name" value="N"/>
        <add key="Type" value="D"/>
    </Setting>
    <Setting id="2">
        <add key="Name" value="O"/>
        <add key="Type" value="E"/>
    </Setting>
    <Setting id="3">
        <add key="Name" value="P"/>
        <add key="Type" value="F"/>
    </Setting>
</CustomConfigSettings>

应用程序配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="customAppSettingsGroup">
      <section name="customAppSettings" type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </sectionGroup>
  </configSections>
  <customAppSettingsGroup>
    <customAppSettings>
      <add key="KeyOne" value="ValueOne"/>
      <add key="KeyTwo" value="ValueTwo"/>
    </customAppSettings>
  </customAppSettingsGroup>
</configuration>

用法：

NameValueCollection settings =  
   ConfigurationManager.GetSection("customAppSettingsGroup/customAppSettings")
   as System.Collections.Specialized.NameValueCollection;

if (settings != null)
{
 foreach (string key in settings.AllKeys)
 {
  Response.Write(key + ": " + settings[key] + "<br />");
 }
}

尝试使用：

var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("MyCustomSections/CustomSection");

您需要节组的名称和自定义节的名称。

Highlight ConfigurationSection press F1, You will see that the implementation on the MSDN website overrides a property called "Properties" which returns a "ConfigurationPropertyCollection", as your properties have a matching attribute of that type you should be able to populate this collection with your properties if not wrap them in the same way the MS guys have.
