修改并运行现有的.NET程序集而不保存到磁盘 [英] Modify and run existing .NET assembly without saving to disk

问题描述

有什么方法可以修改现有.NET程序集中的方法，并在不将其保存到磁盘的情况下执行该程序集?我想要类似于`System.Reflection.Emit.MethodRental` ，但是`Reflection.Emit`名称空间仅处理动态创建的程序集.有许多方法涉及创建新的可执行文件.或修改现有的，但是我想避免做这两个.

我也可以使用CLR事件探查器的JIT编译钩子来重写方法主体，但希望使用可以在C#中完成的方法.该用例是作为探查器的一部分，该探查器在函数入口/出口处输出程序值.

Is there any way to modify methods in an existing .NET assembly, and execute the assembly without saving it to disk? I would like functionality similar to `System.Reflection.Emit.MethodRental` but the `Reflection.Emit` namespace only deals with dynamically created assemblies. There are many approaches that involve creating a new executable. or modifying an existing one, but I would like to avoid doing either of these.

I could use the CLR profiler''s JIT compilation hooks to rewrite the method bodies as well, but would prefer an approach that could be done in C#. The use case is as part of a profiler that outputs program values at function entrance/exit.
