See <a href="http://www.semanticdesigns.com/Products/Clone" rel="nofollow noreferrer">SD CloneDR</a>, a tool for detecting copy-paste-edit code within and across multiple files. It detects exact copyies, copies that have been reformatted, and near-miss copies with different identifiers, literals, and even different seqeunces of statements.

The CloneDR handles many languages, including Java (1.4,1.5,1.6) and C# especially up to C#4.0. You can see sample clone detection reports at the website, also including one for C#.

For Python there is <a href="http://clonedigger.sourceforge.net/" rel="nofollow noreferrer">CloneDigger</a>. It also supports Java but I have not tried that. It can find code duplication both with a single file and between files, and gives you the result as a diff-like report in HTML.

One with some Office skills can do following sequence in 1 minute:

<ul>
<li>use ordinary formatter to unify the code style, preferably without line wrapping</li>
<li>feed the code text into Microsoft Excel as a single column</li>
<li>search and replace all dual spaces with single one and do other replacements </li>
<li>sort column </li>
</ul>

At this point the keywords for duplicates will be already well detected. But to go further

<ul>
<li>add comparator formula to 2nd column and counter to 3rd</li>
<li>copy and paste values again, sort and see the most repetitive lines</li>
</ul>

Sadly, a project that I have been working on lately has a large amount of copy-and-paste code, even within single files. Are there any tools or techniques that can detect duplication or near-duplication within a single file? I have Beyond Compare 3 and it works well for comparing separate files, but I am at a loss for comparing single files.

Thanks in advance.

Edit:

Thanks for all the great tools! I'll definitely check them out.

This project is an ASP.NET/C# project, but I work with a variety of languages including Java; I'm interested in what tools are best (for any language) to remove duplication.

可悲的是，我最近一直在做的一个项目有大量的复制和粘贴代码，甚至在单个文件中也是如此。是否有任何工具或技术可以检测单个文件中的复制或接近复制？我已经超越了比较3，它可以很好地比较不同的文件，但我对比较单个文件感到茫然。提前谢谢。编辑：感谢所有伟大的工具！我一定会去看看的。这个项目是一个ASP.NET/C#项目，但是我使用各种语言，包括Java；我感兴趣的是哪些工具(对于任何语言的，)最适合删除复制。
