修改原因:
thrfit (0.9.2版本)在生成的c#代码,如果thrift server 返回了null,生成的c#代码会抛出错误,提示 "unkown result.".
由于这个异常并不能明确说明sever端返回了null,同时个人觉得如果server端返回了null,客户端自然返回null就是了.
也就是server端返回了什么,客户端就拿到什么,而不应该报错.所以产出了修改源码的想法. (仅是个人想法)
说改就改,在github上clone了thrift项目,然后用vs2010修改了其中的 t_csharp_generator.cc 文件.
(本地编译时报错,解决办法见:http://blog.csdn.net/wilsonpeng3/article/details/41984787)
修改前: (这里贴出来了修改前后的整个文件,可以使用文件比对器查看两个文件的差别 Beyond Compare 不错)
