自定义配置文件C#根据用户的角色重定向用户

我试图编写一个正确的配置文件，但我认为我混淆了几个定义。最终目的是根据用户的角色将其重定向到正确的页面

问题:

• 具有多个标记的嵌套元素不是 ConfigurationElementCollection
• 单个元素不是一个 配置元素

如果这是正确的，下面的代码中哪一个是我的错误

以下是我的例子，我在我的网络配置中写道：

<configSections>
        <section name="adminSecurityConfig" type="Web.Portal.Authentication.ViewModels.RoleConfiguration.AdminSecuritySection" />
</configSections>

<!--Roles for Web Portals and a link to an external file-->
<adminSecurityConfig configSource="AdminSecurity.xml" />

我还有几个类可以访问xml中的元素。我使用->来表示下面字符串上的包含

AdminSecuritySection->RoleCollection->RoleElement（具有角色的name属性）->UrleElementCollection->UrleElement（具有重定向的源）

以下是课程：

• 行政及保安组

  public class AdminSecuritySection : ConfigurationSection
  {
      [ConfigurationProperty("role", IsDefaultCollection = false)]
      ConfigurationCollection(typeof(RoleCollection))]
      public RoleCollection Roles
      {
          get
          {
              return this["role"] as RoleCollection ?? new RoleCollection();
          }
          set { this["role"] = value; }
      }
  }
  

• 角色集合

  {
      public override ConfigurationElementCollectionType CollectionType

          }
      }
  
      protected override ConfigurationElement CreateNewElement()
      {
          return new RoleElement();
      }
  
      protected override object GetElementKey(ConfigurationElement element)

              }
  
              return null;
          }
      }
  }

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

      }
  }
  

• UrlElement

  public class UrlElement : ConfigurationElement
  {
      [ConfigurationProperty("src", IsRequired = true)]
      public string Source
      {
          get { return (string)this["src"]; }
          set { this["src"] = value; }
      }
  }
  

最后，当我尝试运行它时，会出现以下错误：

看起来您的RoleCollection和RoleElement具有相同的名称，即role。这可能令人困惑。当它遇到role标记时，它将被视为没有name属性的角色集合。将RoleCollection名称更改为roles和xml结构，如下所示

<?xml version="1.0" encoding="utf-8" ?>
  <adminSecurityConfig>
    <roles>
     <role name="Employee">
        <redirectUrl src="www.google.com"></redirectUrl>
        <redirectUrl src="www.yahoo.com"></redirectUrl>
        <redirectUrl src="www.amazon.com"></redirectUrl>
     </role>
     <role name="Member">
        <redirectUrl src="www.yahoo.com"></redirectUrl>
     </role>
     <role name="Group Administrator">
     </role>
   </roles>
  </adminSecurityConfig>

那么它不起作用了还是什么？属性名称不起作用看起来您的RoleCollection和RoleElement都有相同的名称，即role。这可能令人困惑。当它遇到role标记时，它被视为没有name属性的role集合。但是在代码中从未设置复数形式的name roles。实际上，如果我添加“unrecognedelement'roles'”这个链接可能会有帮助，那么就会抛出这个异常。
