MonoRail学习笔记九：Rescue的使用
<div class="postBody"><span style="">Rescue是MonoRail中处理异常的一种机制在asp.net或者java开发中我们都要进行异常处理，即发生异常时跳转到某一个错误页面。以前很多时候我们都是自动定义一种方式来处理的，在MonoRail中提供了一种现成的机制来处理异常
使用方式很简单，只要加入一个Rescue属性就可以了。
我们先来看看一个最简单的方式：
Controller代码：
<div style="padding-right: 5px; padding-left: 4px; font-size: 13px; padding-bottom: 4px; width: 98%; padding-top: 4px; background-color: #eeeeee; border: #cccccc 1px solid;">http://writeblog.csdn.net/Images/OutliningIndicators/None.gif"/error")]
