.Net中的异常处理语义是基于类型的，所以你可以创建具有其自己的属性和方法的自定义异常。异常是 .Net 中头等重要的一个元素，因为它是内建的错误处理机制，因此所有 .NET 兼容的语言都必须支持异常。另外, .Net 代码可以将 COM+ 服务作为 Enterprise Services（企业服务）来获得，所以你可以在 Enterprise Services 设计中定制异常。本程序的功能是从服务性组件产生定制异常，该组件被配置在一个 COM+ 服务器应用环境中执行（相对于库应用环境）。-. Net in the exception handling is based on the type of semantics, so you can create with their own properties and methods of self-definition of abnormal. Abnormal. Net of the most important element, because it is built-in error handling mechanism, all. NET-compliant languages must support the anomaly. In addition,. Net code can COM+ Service as part of the Enterprise Services (Corporate Services) to obtain, so you can customize the design of Enterprise Services abnormal. This procedure s function is generated from the service components custom anomaly, the component is configured in a COM+ Server application environment to implement (as opposed to database application environment).
