如何使用 ELMAH 手动记录错误 [英] How to use ELMAH to manually log errors

问题描述

是否可以使用 ELMAH 执行以下操作?

Is it possible to do the following using ELMAH?

logger.Log(" something");

我正在做这样的事情:

try 
{
    // Code that might throw an exception 
}
catch(Exception ex)
{
    // I need to log error here...
}

ELMAH 不会自动记录此异常，因为它已被处理.

This exception will not be automatically logged by ELMAH, because it was handled.

推荐答案

直接写日志的方法，从ELMAH 1.0开始工作:

Direct log writing method, working since ELMAH 1.0:

try 
{
    some code 
}
catch(Exception ex)
{
    Elmah.ErrorLog.GetDefault(HttpContext.Current).Log(new Elmah.Error(ex));
}

ELMAH 1.2 引入了更灵活的 API:

ELMAH 1.2 introduces a more flexible API:

try 
{
    some code 
}
catch(Exception ex)
{
    Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
}

两种解决方案之间存在差异:

There is a difference between the two solutions:

• Raise 方法将 ELMAH 过滤规则应用于异常.Log 方法没有.
• Raise 是基于订阅的，能够将一个异常记录到多个记录器中.

• Raise method applies ELMAH filtering rules to the exception. Log method does not.
• Raise is subscription based and is able to log one exception into the several loggers.
