Tool to check code duplication in C#

I need to check if my codes have a duplication. Is there any free application for code d开发者_开发技巧uplication refactoring tool for C#?

Check :

Simian (http://www.redhillconsulting.com.au/products/simian/), based on source code. Works with plenty languages.

Clone Detective a Visual Studio plugin (http://www.codeplex.com/CloneDetectiveVS). (It uses ConQAT internally)

TeamCity has a duplicates search if you are already using TeamCity.

I've used Simian - Similarity Analyser. It is a command line tool, but it works well.
