.Net反編譯工具Reflector它是一個類瀏覽器和反編譯器，可以分析程序集並向您展示它的所有祕密，反編譯.EXE .DLL .MCL格式的文件。.net 框架向全世界引入了可用來分析任何基於 .net 的代碼（無論它是單個類還是完整的程序集）的反射概念。反射還可以用來檢索有關特定程序集中包含的各種類、方法和屬性的信息。使用 .net reflector，您可以瀏覽程序集的類和方法，可以分析由這些類和方法生成的 microsoft 中間語言 (msil)，並且可以反編譯這些類和方法並查看 c# 或 visual basic .net 中的等價類和方法。
Reflector插件使用方法：
以FileDisassembler這個插件爲例（它可以把exe或dll文件反編譯成原始的cs文件，反編譯的效果相當好，99%都是正確的，只有一些註釋等會有錯誤。），先根據下面的地址下載過來並解壓縮，然後運行Reflector.exe，然後點擊View->Add- Ins，彈出一個窗口，然後點擊Add->選擇你下載過來的Reflector.FileDisassembler.dll插件，再點擊close。到此插進裝載完畢。
然後回到Reflector窗口，Tool->File Disassembler，右邊就出現了插件的窗口，File->Open打開你要反編譯的DLL文件，然後選中左邊的dll文件，點擊右邊插件的相關功能導出文件，源代碼就全部導出來了。當然這樣就還原的源碼可不是完全還原，然後自己加上註釋，少許修改，就是真正的源碼了。
