注解

通过调用 RegisterBusinessLogicHandler注册业务逻辑处理程序。 在调用 RegisterBusinessLogicHandler之前，必须设置 对象的属性BusinessLogicHandler。

通过调用 UnregisterBusinessLogicHandler删除业务逻辑处理程序注册。

调用 EnumBusinessLogicHandlers 以获取在服务器上注册的业务逻辑处理程序的列表。

构造函数

BusinessLogicHandler()

初始化 BusinessLogicHandler 类的新实例。

属性

DotNetAssemblyName	获取或设置实现业务逻辑处理程序的程序集的名称。
DotNetClassName	获取或设置实现业务逻辑处理程序的类的名称。
FriendlyName	获取或设置在服务器上注册业务逻辑处理程序的名称。
IsDotNetAssembly	获取或设置一个值，该值指示已注册的业务逻辑处理程序是否为托管代码程序集。
UserData	获取或设置用户可以将他们自己的数据附加到的对象。

方法

CheckValidDefinition(Boolean)

指示定义是否有效。
