如何摆脱编译器错误：项目需要代码合同 [英] How to get rid of compiler error: Project requires code contracts

问题描述

我正在尝试将合同实施到现有的代码库中并且遇到问题  PDF文档第5.1.3节中给出的建议，建议将项目组和目标添加到项目文件中，以警告其他开发人员需要
CodeContracts。如果没有这个文本块（我在最后，就在< / Project>之前添加），我的代码就会编译。有了它，我收到编译错误：

I am trying to implement Contracts into an existing code base and am having problems with  advice given in section 5.1.3 of the PDF documentation which advises adding a project group and target to projects files as a warning to other developers that CodeContracts are required. Without this block of text (which I add, right at the end, just before </Project>) my code compiles. With it, I receive compilation error:

我的项目定位于'.NET Framework 4'，我已经下载并安装了Code Contracts 1.4.30903我开始了，为什么我会收到这些错误？并且，更有针对性的是，如何在向我的
开发者提供有用信息的同时停止获取它们？

My project is targeting '.NET Framework 4' and I downloaded and installed Code Contracts 1.4.30903 before I started, so why am I getting these errors? And, more pertinently, how can I stop getting them while still providing useful information to my fellow developers?

谢谢

推荐答案

看起来PDF文本/副本中有一个错误，它在单引号内的单词true之后插入一个空格。也就是说，当我从pdf复制时，我得到'真'，有空格，而那个空格不应该在那里：'真'。

Looks like there is a bug in the PDF text/copy which inserts a space after the word true inside the single quotes. Ie., when I copy from pdf, I get 'true ', with the space, whereas that space should not be there: 'true'.

如果删除那个空格，它就有效。

If you remove that space, it works.

这是它应该是什么：

 <PropertyGroup>
  <CompileDependsOn>

（CompileDependsOn）; CheckForCodeContracts < / CompileDependsOn >
< / < span style ="color：＃A31515;"> PropertyGroup >
< 目标 名称 = " CheckForCodeContracts "
条件 = " '

(CompileDependsOn);CheckForCodeContracts</CompileDependsOn> </PropertyGroup> <Target Name="CheckForCodeContracts" Condition="'

（CodeContractsImported）'！='true' " >
< 错误 文字 = " 项目需要代码合约http://msdn.microsoft.com/en-us/devlabs/ dd491992.aspx " />
< / 目标 >

(CodeContractsImported)' != 'true'"> <Error Text="Project requires Code Contracts http://msdn.microsoft.com/en-us/devlabs/dd491992.aspx"/> </Target>
