I have working on a web app for almost 2 years now and a lot unnecessary code(c#, html, js, css ) has accumulated in it. I have been trying to clean it up for a while now but with not great success.
Can you guys sugest ways(tools) by which i speed up this process.
也许您应该尝试使用Resharper。应该可以在 Visual Studio 中正常工作。
What you are trying to do is called refactoring. Most IDEs provide automated support for it to a greater or lesser extent (depending on the language too) - check out yours.
It's no silver bullet - you still have to think, plan, write unit/functional tests to ensure you are not breaking anything, etc. But there are known methods and processes in place, which help you a lot.
