//WinConfiguration.cs

using System;
using System.Configuration;
namespace BANANA.Common
{
    public class WinConfiguration : ConfigurationSection
    {
        public readonly static BANANA.Common.WinConfiguration Settings
            = (BANANA.Common.WinConfiguration)System.Configuration.ConfigurationManager.GetSection("BANANA");
        [ConfigurationProperty("connections")]
        public ConnectionsCollection Connections
        {
            get { return (ConnectionsCollection)this["connections"]; }
        }
        [ConfigurationProperty("cryptography")]
        public CryptographyCollection Cryptography
        {
            get { return (CryptographyCollection)this["cryptography"]; }
        }
    }
}

//app.config

<?xml version="1.0"?>
<configuration>
    <configSections>
        <section name="BANANA" type="BANANA.Common.WinConfiguration"/>
    </configSections>
    <BANANA>
        <connections>
            <add name="SqlServer2008" connectionString="" providerName="System.Data.SqlClient" priority="100" />
        </connections>
        <cryptography>
            <add type="DES" value="12345" />
            <add type="TripleDES" value="12345" />
        </cryptography>
    </BANANA>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    </startup>
</configuration>

它过去在web.config中工作得很好。我刚改了类名。这是我的web.config和自定义配置类。

//WebConfiguration.cs

using System;
using System.Configuration;
namespace BANANA.Common
{
    public class WebConfiguration : ConfigurationSection
    {
        public readonly static BANANA.Common.WebConfiguration Settings = (BANANA.Common.WebConfiguration)System.Web.Configuration.WebConfigurationManager.GetSection("BANANA");
        [ConfigurationProperty("connections")]
        public ConnectionsCollection Connections
        {
            get { return (ConnectionsCollection)this["connections"]; }
        }
        [ConfigurationProperty("cryptography")]
        public CryptographyCollection Cryptography
        {
            get { return (CryptographyCollection)this["cryptography"]; }
        }
    }
}

//web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="BANANA" type="BANANA.Common.WebConfiguration"/>
    </configSections>
    <BANANA>
        <connections>
            <add name="SqlServer2008" connectionString="" providerName="System.Data.SqlClient" priority="100" />
        </connections>
        <cryptography>
            <add type="DES" value="12345" />
            <add type="TripleDES" value="12345" />
        </cryptography>
    </BANANA>
</configuration>

它只适用于WebConfiguration.cs和web.config。但是对于WinConfiguration.cs和app.config，它会给我一些错误，比如"'BANANA.Common.WinConfiguration'的类型初始值设定项引发了异常"。有人能帮我纠正这个错误吗？

app.config中的自定义节在c#中引发错误

我认为您必须指定配置类所在的程序集名称（EXE或DLL的名称）：

<section name="BANANA" type="BANANA.Common.WinConfiguration, YOUR_ASSEMBLY_NAME"/>
