为什么ResourceManager.GetResourceSet在构建后的第一个请求返回null？ （C＃） [英] Why does ResourceManager.GetResourceSet return null on the first request after a build? (C#)

问题描述

我正在建在C＃（asp.net）大十岁上下的Web应用程序。我有供应本地化字符串为在JavaScript控件使用客户端浏览器一个简单的aspx页面。要获取字符串，我做到以下几点：

I'm working on a large-ish web application built in C# (asp.net). I've got a simple aspx page that serves localized strings to the client browser for use in javascript controls. To get the strings, I do the following:

ResourceManager _resources = new ResourceManager(_pathname, typeof(ARM).Assembly);
ResourceSet rs = _resources.GetResourceSet(culture, false, false);

//loop through rs and write the keys & values out to the client in plaintext

这一切后，立即清洁工作正常，除第一次请求的页面/建造或重建（如果我只是做一些改变，然后生成，它工作正常）。因此，在第一次请求我得到一个空引用异常，当我尝试迭代的ResourceSet。如果我刷新页面的错误后，但是，它工作正常，从此。

This all works fine, except for the first request to the page immediately after a Clean/Build or a Rebuild (if I simply make some changes, then Build, it works fine). So on the first request I get a null reference exception when I try to iterate the ResourceSet. If I refresh the page after the error, however, it works fine from then on.

有谁知道为什么这可能发生？

Does anyone know why this might be happening?

推荐答案

GetResourceSet必须是真实的方法的第二参数createIfNotExist，告诉的ResourceManager加载的ResourceSet如果尚未加载。

Second param "createIfNotExist" of the method GetResourceSet has to be true, that tells ResourceManager to load the ResourceSet if not yet loaded.

ResourceSet rs = _resources.GetResourceSet(culture, true, false);
