public class GroupCollection : ConfigurationElementCollection

三、测试
ok，下面测试一下，首先要在FilterConfig的RegisterGlobalFilters方法中在，HandlerErrorAttribute前注册我们的过滤器：
filters.Add(new SettingHandleErrorFilter())。
3.1 准备异常对象
准备几个简单的异常对象：
public class PasswordErrorException : Exception{}
public class UserNameEmptyException : Exception{}
public class EmailEmptyException : Exception{}
3.2 准备Handler
针对上面的异常，我们准备两个Handler，一个处理密码错误异常，一个处理空异常。这里没有实际处理代码，具体怎么处理，应该结合具体业务了。如：
public class PasswordErrorExceptionHandler : IExceptionHandler
{
public bool HasHandled{get;set;}
public void Handle(Exception ex)
{
//具体处理逻辑...
}
}
public class EmptyExceptionHandler : IExceptionHandler
{
public bool HasHandled { get; set; }
public void Handle(Exception ex)
{
//具体处理逻辑...
}
}
