SecurityRoleAttribute 类


为应用程序或组件配置角色。Configures a role for an application or component. 此类不能被继承。This class cannot be inherited.

public ref class SecurityRoleAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Interface | System.AttributeTargets.Method, AllowMultiple=true, Inherited=true)]
public sealed class SecurityRoleAttribute : Attribute
type SecurityRoleAttribute = class
    inherit Attribute
Public NotInheritable Class SecurityRoleAttribute
Inherits Attribute


下面的代码示例演示如何使用此特性将角色与包含ServicedComponent类的程序集相关联。The following code example demonstrates the use of this attribute to associate a role with an assembly that contains ServicedComponent classes.

// Create a security role for the component.
// Create a security role for the component.
[assembly: SecurityRole("Manager")]
' Create a security role for the component.
<Assembly: SecurityRole("Manager")> 


可以使用SecurityRoleAttribute将角色添加到应用程序,并将其与组件关联。You can use the SecurityRoleAttribute to add roles to an application, and to associate them with components. SecurityRoleAttribute作为一个整体应用于程序集时,它将确保应用程序配置(com + 目录)中存在该角色。When SecurityRoleAttribute is applied to an assembly as a whole, it ensures that the role exists in the application configuration (COM+ catalog). 您可以使用 COM + 资源管理器添加角色的成员。You can add members of the role using the COM+ Explorer.

当应用于组件时,将SecurityRoleAttribute确保角色存在于应用程序配置中,并将目标组件与角色相关联。When applied to a component, the SecurityRoleAttribute ensures that the role exists in the application configuration, and associates the target component with the role.

默认情况下,创建的角色不包含任何成员。By default, created roles have no members. true如果将SetEveryoneAccess属性设置为,则 Everyone 用户组将自动添加到角色。If the SetEveryoneAccess property is set to true, the Everyone user group is automatically added to the role. 这最适用于对系统具有最小控制控制权限的所有访问类型角色。This is best for all-access type roles that are given minimal control over the system.

可以在组件级别、每个接口和按方法指定安全角色。Security roles can be specified at the component level, per interface and per method. 与其他方法属性一样,安全配置当前不在接口定义和方法实现之间共享。As with other method attributes, security configuration is not currently shared between interface definition and method implementation.
