Puresys纯净系统-软件下载介绍
官方网站：https://github.com/icsharpcode/ILSpy/
尽管有许多类似的工具可供使用，但 ILSpy 非常易于使用以及免费和开源。它不需要任何安装，这意味着它可以保存到您的便携式应用程序集合中，复制到 USB 闪存驱动器，并且可以在任何PC上使用而无需设置来浏览和检查 .NET 程序集。

软件特点
使用此工具仔细查看.NET程序集
主应用程序窗口具有清晰的布局，分为两个主窗格：用于浏览 .NET 程序集树以及仔细查看任何选定项目。它可以检查 DLL，EXE 和 WINMD 文件（Windows 元数据）。可以从 GAC 加载数据，也可以打开 Nuget 包。
ILSpy 能够使用 C＃ 在 C＃，IL 和 IL 中呈现代码。对于 C＃，您可以选择 C＃1.0/VS .NET 到 C＃7.2/VS 2017。例如，您可以查看资源和引用，查看表以及将信息提取到文件。
使用 C＃ 在 C＃，IL 和 IL 中呈现代码
由于该程序仅用于查看目的，因此无法进行文件修改。另一方面，您可以在查找类型，成员，方法，字段，属性，事件，常量或元数据标记时利用搜索功能。
可以配置多个反编译器设置，例如使用调试符号中的变量名称，删除无死区和副作用的代码，或者在反编译后扩展成员定义。此外，您可以自定义字体并允许多个实例。
考虑到所有方面，IlSpy 尽可能简单地反编译 .NET 程序集，看看是什么让软件变得简单。由于它是开源的，开发人员可以随意修改和使用其代码。
