Question

我正在尝试从.NET 4.0应用程序中的自定义配置部分读取值。但是，在检查值时，它们始终显示默认值，而不是我期望的自定义值。

这是我的班级：

using System;
using System.Configuration;

namespace TestNamespace
{
    public class TestSection : ConfigurationSection
    {
        [ConfigurationProperty("applicationAccessID", IsRequired = true)]
        public string ApplicationAccessID { get; set; }

        [ConfigurationProperty("username", IsRequired = true)]
        public Guid Username { get; set; }

        [ConfigurationProperty("password", IsRequired = true)]
        public Guid Password { get; set; }
    }
}

我已将以下项目添加到配置文件中：

<configuration>
  <configSections>
    <sectionGroup name="myCustomConfiguration">
      <section name="testSection" type="TestNamespace.TestSection,MyAssembly"/>
    </sectionGroup>
  </configSections>
  <myCustomConfiguration>
    <myAuthenticationSection applicationAccessID="1" username="9A36EC78-76B0-477B-9E36-613C13AE86BB" password="589A8696-2B9B-4ADD-906E-7245D387B594" />
  </myCustomConfiguration>
...

此行返回TestSection的实例，但它不是从配置中读取自定义值：

ConfigurationManager.GetSection("myCustomConfiguration/myAuthenticationSection")

有什么建议吗？

编辑：删除组后，这是我更新的配置文件：

<configuration>
  <configSections>
    <section name="testSection" type="TestNamespace.TestSection,MyAssembly"/>
  </configSections>
  <myAuthenticationSection applicationAccessID="1" username="9A36EC78-76B0-477B-9E36-613C13AE86BB" password="589A8696-2B9B-4ADD-906E-7245D387B594" />
...

您正在使用群组，因此您还需要实施群组处理程序：

public class MySettingsConfigurationGroup : ConfigurationSectionGroup
{
}

更新

public class TestSection : ConfigurationSection
{
    private static TestSection _testSection 
      = ConfigurationManager.GetSection("TestSection") as TestSection;

    public static TestSection Settings
    {
      get
      {
        return _testSection;
      }
    }

    [ConfigurationProperty("applicationAccessID", IsRequired = true)]
    public string ApplicationAccessID { get; set; }

    [ConfigurationProperty("username", IsRequired = true)]
    public Guid Username { get; set; }

    [ConfigurationProperty("password", IsRequired = true)]
    public Guid Password { get; set; }

}

string id = TestSection.Settings.applicationAccessID;

此外，名称需要匹配：

<testSection applicationAccessID="1" username="9A36EC78-76B0-477B-9E36-613C13AE86BB" password="589A8696-2B9B-4ADD-906E-7245D387B594" />

我不知道这个问题是否仍然有效，但无论如何。

在处理ConfigurationElement时，您需要解决配置元素是值集合的问题，因此您不读取值。

我会替换这样的东西：

[ConfigurationProperty("applicationAccessID", IsRequired = true)] 
public string ApplicationAccessID 
{ 
   get { return (string)this["applicationAccessID"]; } 
   set { this["applicationAccessID"] = value; }
} 

[ConfigurationProperty("username", IsRequired = true)] 
public Guid Username
{ 
   get { return (Guid)this["username"]; } 
   set { this["username"] = value; }
} 

[ConfigurationProperty("password", IsRequired = true)] 
public Guid Password 
{ 
   get { return (Guid)this["password"]; } 
   set { this["password"] = value; }
}

从自定义配置部分读取不在.NET中工作
