实现本地化多语言我做的一些思想,希望大家共同探讨一些.

一直想做个好的本地化语言的东西,但是技术太差了,做也做不好,借此发布我的一些东西,共同探讨一下.

一般用资源文件都会以dll的形式加载到内存中,但是如果是多语言的话,会造成dll过大,而程序需要加载的时间太

长,所以用Assembly.LoadFrom方法你URL的形式动态加载Dll,把一种语言做一个dll.减少dll加载的时间.但是这样也有很个问题就是每次打开页面都要Assembly.LoadFrom,重新加载dll造成程序太慢了。由此我想到了单件模式去做,

声明private Assembly asm;改asm为static变量,如果asm!=null就不加载,但是static变量是在编译是分配,浏览器关闭时,GC才回收.又不能随意做语言切换.欢迎有兴趣的一起探讨.
