Custom Config section in App.config C#
提问by Chaturvedi Dewashish
I'm a quite beginner with config sections in c#
I want to create a custom section in config file. What I've tried after googling is as the follows
Config file:
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
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; }
}
}
}
When I use this code to retrieve Section I get an error saying configuration error.
当我使用此代码检索 Section 时，我收到一条错误消息，指出配置错误。
var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("CustomSection");
What am I missing?
Thanks.
Edit
What I need ultimately is
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>

App.config:
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>
Usage:
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 />");
}
}

Try using:
尝试使用：
var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("MyCustomSections/CustomSection");
You need both the name of the section group and the custom section.
您需要分区组和自定义分区的名称。

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.
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，该属性返回一个“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以与 MS 人员相同的方式包装它们。
