本文解释了在.NET框架中，CodeBase与Location属性的区别。CodeBase通常指向文件的原始位置，例如从互联网下载的文件其CodeBase可能包含HTTP链接；而Location属性则表示实际加载路径，如果是硬盘上的文件，则Location会指向具体的磁盘路径。如果文件被影子复制，Location会指向影子副本的位置。值得注意的是，对于全局程序集缓存(GAC)中的程序集，CodeBase可能未设置，但Location总是有值。
The CodeBase is a URL to the place where the file was found, while the Location is the path from where it was actually loaded. For example, if the assembly was downloaded from the internet, its CodeBase may start with "http://", but its Location may start with "C:\". If the file was shadow copied, the Location would be the path to the copy of the file in the shadow-copy dir.
It’s also good to know that the CodeBase is not guaranteed to be set for assemblies in the GAC. Location will always be set for assemblies loaded from disk, however.
