示例

下面的示例演示如何使用IsInRole方法重载。The following example demonstrates how to use the IsInRole method overloads. WindowsBuiltInRole枚举标识内置角色的相对标识符 (Rid) 用作源。The WindowsBuiltInRole enumeration is used as the source for the relative identifiers (RIDs) that identify the built-in roles. Rid 用于确定当前主体的角色。The RIDs are used to determine the roles of the current principal.

      Console::WriteLine( "{0} belongs to: ", myPrincipal->Identity->Name );

      Array^ wbirFields = Enum::GetValues( WindowsBuiltInRole::typeid );

      for each ( Object^ roleName in wbirFields )

注解

WindowsPrincipal类主要用于检查 Windows 用户的角色。The WindowsPrincipal class is primarily used to check the role of a Windows user. WindowsPrincipal.IsInRole方法重载允许您使用不同的角色上下文检查用户角色。The WindowsPrincipal.IsInRole method overloads let you check the user role by using different role contexts.
