内容简介:阅读关于System.Diagnostics.Contracts.Contract受静态类影响的静态类后,我很高兴,并立即开始对Call.Requires()和Contract.Ensures()的调用进行编码.我想这只是因为我的代码是非常棒的,没有bug的,检查那些电话实际上做的只是直到最近才出现.一个错误滑过来,我意识到这些电话没有做任何事情!我本来以为他们至少在违反条件时抛出异常,但没有这样的运气.我错过了什么吗?有人知道这是什么意思吗?

You must use a binary rewriter to insert run-time enforcement of contracts. Otherwise, contracts such as the Contract.Ensures method can only be tested statically and will not throw exceptions during run time if a contract is violated. You can download the binary rewriter CCRewrite from Code Contracts on the MSDN DevLabs Web site. CCRewrite comes with a Visual Studio add-in that enables you to activate run-time contract enforcement from the project Properties page. The binary rewriter and the Visual Studio add-in do not ship with Visual Studio 2010 or the Windows SDK.
