Spring.NET 缓存遇到问题
我一直在阅读这篇文章来帮助我进行缓存，但遇到了问题。当我尝试调用下面的方法时，出现以下错误：
"Cannot initialize property or field node 'LocalTariffId' because the specified context is null."
我认为下面使用的属性语法一旦返回以缓存我的数据，就会使用结果的 LocalTariffId 属性。当我尝试进入该方法时，就会出现此错误。在我看来，它试图过早地访问该属性。我一定错过了一些东西，所以非常感谢您提供的任何建议！
[CacheResult("AspNetCache", "'LocalTariff.Id=' + LocalTariffId", TimeToLive = "00:10:00")]
public Domain.LocalTariffs.LocalTariff GetDefault(string agencyCode)
在第一个错误之后我也遇到了一个奇怪的错误，我希望有人能够阐明这一点。至少我认为它与 log4net 有关。我的日志记录正在运行，所以我不确定这是关于什么的。

I have been reading this post to help me get going on my caching and am running into a problem. When I attempt to do a call to the method below I get the following error:
"Cannot initialize property or field node 'LocalTariffId' because the specified context is null."
I thought the attribute syntax I am using below would use the LocalTariffId property of the result once it returns to cache my data. This error occurs as soon as I attempt to step into the method. It seems to me that it is trying access that property too soon. I must be missing something so any advice you could provide is greatly appreciated!
[CacheResult("AspNetCache", "'LocalTariff.Id=' + LocalTariffId", TimeToLive = "00:10:00")]
public Domain.LocalTariffs.LocalTariff GetDefault(string agencyCode)
I am also getting a weird error after the first error I was hoping somebody could shed some light on. It has to do with log4net at least I think it does. My logging is working so I am not sure what this one is about.

您不能使用返回的对象来生成 CacheResult 属性的键。
您必须使用该方法的参数来生成密钥（此处为“#agencyCode”）。
You can't use the returned object to generate the key of the CacheResult attribute.
You have to use parameters of the method to generate the key (here '#agencyCode').
