C# ConfigurationSection 属性为空

Question

大家晚上好，我正在做一个小项目，我写的 ConfigurationSection 没有返回我在 web.config.

中输入的数据

在此处输入代码

我的代码：

public class AdminSection : ConfigurationSection
    {
        private static AdminSection uniqueInstance;

    public static AdminSection Instance
    {
        get { return uniqueInstance ?? (uniqueInstance = new AdminSection()); }
    }


    private AdminSection()
    {          
    }

    [ConfigurationProperty("Username", IsRequired =true)]
    public  String Username
    {
        get { return (String)this["Username"]; }
    }

    [ConfigurationProperty("Password",  IsRequired = false)]
    public String Password
    {
        get { return (String)this["Password"]; }
    }
}

这是我的 web.config

<configuration>
  <configSections>
    <section name="Admin" type="cms.Configs.AdminSection, cms.cms"/>
  </configSections>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>

  <appSettings>
    <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
  </appSettings>
  <Admin>
    <Username>test</Username>
    <Password>test2</Password>
  </Admin>
</configuration>

当我尝试调用以下内容时

Username.Value == Configs.AdminSection.Instance.Username

我没有从 AdminSection 获得任何值。

你们中有人知道我可能做错了什么吗？

找到遮阳篷我忘了做以下事情：

public 管理员部分管理员

{
    get
    {
        try
        {
            if (_instance == null)
            {
                _instance = ConfigurationManager.GetSection("Admin") as AdminSection;   
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        return _instance;
    }
}
