  • 参考

定义

命名空间:
System.Web.Profile
程序集:
System.Web.dll

获取或设置按属性名进行索引的分组配置文件属性值。

public:
 property System::Object ^ default[System::String ^] { System::Object ^ get(System::String ^ propertyName); void set(System::String ^ propertyName, System::Object ^ value); };
public object this[string propertyName] { get; set; }
member this.Item(string) : obj with get, set
Default Public Property Item(propertyName As String) As Object

参数

propertyName
String

分组配置文件属性的名称。

属性值

Object

指定的分组配置文件属性的值。

示例

下面的代码示例演示一个 ASP.NET 页，该页读取和设置为用户配置文件指定的分组属性。 有关在配置文件中指定一组属性的 Web.config 文件的示例，请参阅为 ProfileGroupBase 类提供的示例。

重要

此示例包含一个接受用户输入的文本框，这是一个潜在的安全威胁。 默认情况下，ASP.NET 网页验证用户输入是否不包含脚本或 HTML 元素。 有关详细信息，请参阅脚本侵入概述。

注解

可以使用此属性检索或设置应用程序的用户配置文件的分组属性值。 返回的值类型化为 Object ，检索时必须强制转换为特定对象类型。 对于对配置文件属性值的强类型访问，可以按名称作为属性组 HttpContext.Profile 的成员访问属性， Profile.Address.City例如 。
