Open Source Alternatives to Reflector? [closed]

问题:

Just to ask if anyone knows of an open source alternative to RedGate\'s Reflector? I\'m interested in checking out how a tool similar to Reflector actually works.

Note, if you know of a free but not open source alternative to Reflector, you can answer the following related question:

• Something Better than .NET Reflector?

Summary - Updated 11th May 2011

A quick round-up of the various open source projects and tools that have been suggested:

1. Common Compiler Infrastructure (CCI)
2. Mono Cecil
3. ILSpy
4. dnSpy (fork of ILSpy, project appears more active than original)
5. Dotnet IL Editor (DILE)
6. IL.View
7. Monoflector (no longer active as of April 2011)

The following resources may also be of interest:

• TypeView.cs
• Jason Haley\'s notes on disassembling .NET
• Adrian Bank\'s recent blog post summarising a number of Reflector alternatives, including several options not mentioned below.
• Mark Lichtenberg\'s detailed blog post comparing several of the open source alternatives (DILE, ILSpy and Mono Cecil using MonoDevelop) to Reflector.

回答1:

2 options I know of.

• CCI
• Mono Cecil

These wont give you C# though.

Updated 13th December 2011

The following open source tools are available:

• ILSpy from the SharpDevelop team. Thanks to Scott Hanselman\'s tweet highlighting the tool.
• Dotnet IL Editor (a disassembler)
• IL.View - a .NET Reflector alternative written in Silverlight 4 as an Out-of-Browser Silverlight Application. See this blog post for details.

Another replacement would be dotPeek. JetBrains announced it as a free tool. It will probably have more features when used with their Resharper but even when used alone it works very well.

User experience is more like MSVS than a standalone disassembler. I like code reading more than in Reflector. Ctrl+T navigation suits me better too. Just synchronizing the tree with the code pane could be better.

All in all, it is still in development but very well usable already.

回答4:

Telerik today released a Beta of their own decompilation tool, JustDecompile. Closed source, but free and looks promising.

回答5:

ILSpy works great!

As far as I can tell it does everything that Reflector did and looks the same too.

回答6:

Actually, I\'m pretty sure Reflector is considered a disassembler with some decompiler functionality. Disassembler because it reads the bytes out of an assembly\'s file and converts it to an assembly language (ILasm in this case). The Decompiler functionality it provides by parsing the IL into well known patterns (like expressions and statements) which then get translated into higher level languages like C#, VB.Net, etc. The addin api for Reflector allows you to write your own language translator if you wish ... however the magic of how it parses the IL into the expression trees is a closely guarded secret.

I would recommend looking at any of the three things mentioned above if you want to understand how IL disassemblers work: Dile, CCI and Mono are all good sources for this stuff.

I also highly recommend getting the Ecma 335 spec and Serge Lidin\'s book too.

回答7:

The main reason I used Reflector (and, I think, the main reason most people used it) was for its decompiler: it can translate a method\'s IL back into source code.

On that count, Monoflector would be the project to watch. It uses Cecil, which does the reflection, and Cecil.Decompiler, which does the decompilation. But Monoflector layers a UI on top of both libraries, which should give you a very good idea of how to use the API.

Monoflector is also a decent alternative to Reflector outright. It lets you browse the types and decompile the methods, which is 99% of what people used Reflector for. It\'s very rough around the edges, but I\'m thinking that will change quickly.

回答8:

Well, Reflector itself is a .NET assembly so you can open Reflector.exe in Reflector to check out how it\'s built.

回答9:

I am currently working on an open-source disassembler / decompiler called Assembly Analyzer. It generates source code for methods, displays assembly metadata and resources, and allows you to walk through dependencies.

The project is hosted on CodePlex => http://asmanalyzer.codeplex.com/

回答10:

The Reflector tool uses Reflection.  - apparently this is not correct.

You asked for two things - code that shows what reflector does, and also an alternative to reflector.

Here\'s an example, much simplified from what Reflector does, but it shows the technique of reflection: TypeView.cs

I don\'t have a suggestion for an open-source Reflector replacement.
