【问题描述】:
我正在使用 Mono.Cecil.dll 反编译 VS 2015 应用程序。 在反编译期间,我注意到缺少 2 条指令(stloc.0 和 ldloc.0)。 当我反编译一个 VS 2013 应用程序时,这并没有发生。
是反编译器有问题还是Visual Studio 2015编译器改了?
更新:
我已经使用 ILDasm 反编译了代码。这是 2015 年和 2013 年可以在 Initialize 组件中找到的内容。问题依旧出现:

【问题讨论】:
-
您可以将代码复制为文本并粘贴吗?
-
我怀疑也不需要这么多代码。最好展示一下:a)C#; b) VS2013生成的IL; c) 2015 年生成的 IL。还要注意您正在使用的选项(例如调试或发布版本)。
