不知道自己做了什么样的操作，于是出现上面的错误提示
google了一下
先删除了bin目录,编译，还是不行
然后按

上面说的
再去国外的站点，查找"asp.net,CS1595 , is defined in multiple places",
发现论坛里有篇回复“I have come across it a couple of times. Usually if you have two dlls in your bin folder that contain the same thing. for example I renamed one of my dlls in the compile script but forgot to remove the old version. Check your bin folder and then head over to c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\ and clear it. ”
清除该目录下的文件，结果还是出错，到底是怎么一回事呢？求解
