注解

ASP.NET 角色管理旨在使你能够轻松地为 ASP.NET 应用程序使用多个不同的角色提供程序。ASP.NET role management is designed to enable you to easily use a number of different role providers for your ASP.NET applications. 您可以使用 .NET Framework 附带的提供的角色提供程序, 也可以实现您自己的提供程序。You can use the supplied role providers that are included with the .NET Framework, or you can implement your own provider.

实现自定义角色提供程序时, 需要继承RoleProvider抽象类。When implementing a custom role provider, you are required to inherit the RoleProvider abstract class.

创建自定义角色提供程序的主要原因有两个。There are two primary reasons for creating a custom role provider.

  • 您需要将角色信息存储在 .NET Framework 中包含的角色提供程序不支持的数据源中, 如 FoxPro 数据库、Oracle 数据库或其他数据源。You need to store role information in a data source that is not supported by the role providers included with the .NET Framework, such as a FoxPro database, an Oracle database, or other data sources.

  • 需要使用与 .NET Framework 附带的提供程序所使用的数据库架构不同的数据库架构来管理角色信息。You need to manage role information using a database schema that is different from the database schema used by the providers that ship with the .NET Framework. 这种情况的一个常见示例是公司或网站的 SQL Server 数据库中已存在的角色数据。A common example of this would be role data that already exists in a SQL Server database for a company or Web site.
