Can C# Reflection Access Method Code?

Can C# reflection expose method code?

Question:

A developer wanted to explore the power of C# reflection, but ran into a roadblock: the inability to access the actual code inside a method.

Answer:

Short answer:

Method code cannot be accessed using only reflection (System.Reflection).

Detailed explanation:

Reflection dives deep into metadata, inspecting class types, method signatures, and other advanced properties. However, it does not provide access to low-level data such as the bytecode (IL) of method implementations.

Advanced Insights:

Although reflection does not facilitate code inspection, there are other ways:

• IL code generation: Use System.Reflection.Emit to write IL code without looking at the code directly.
• IL code acquisition: MethodInfo.GetMethodBody() can obtain the binary IL stream of a method, but its utility is limited.
• External libraries: Third-party tools like Cecil enable developers to manipulate method code (read, modify, add, or delete).
