Question

我是c＃
中配置部分的初学者我想在配置文件中创建自定义部分。我在google搜索后尝试的内容如下配置文件：

    <?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Section时，我收到一条错误说配置错误。

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

我错过了什么？
谢谢。

的修改
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>

Answer 1

<强> App.config中：

<?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>

<强>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 />");
 }
}

Answer 2

尝试使用：

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

您需要部分组的名称和自定义部分。

Answer 3

突出显示ConfigurationSection按F1，您将看到MSDN网站上的实现覆盖了一个名为“Properties”的属性，该属性返回“ConfigurationPropertyCollection”，因为您的属性具有该类型的匹配属性，您应该能够使用您的属性填充此集合，如果不将它们包装在与MS家伙一样。
