Reflection technology can be obtained at runtimeProgramSet members of each type, including fields, methods, attributes, and events, and further obtain detailed information about these members. Reflection technology can also dynamically
Before JIT
When CLR calls a method for the first time, the JIT code is required first.
Previously, the CLR was required to ensure that all required assemblies can be loaded successfully. If load succeeds, CLR will use metadata in Assembly to

Mechanism: After a class is correctly compiled, in this properly compiled class, there is an Isa pointer to store the class's method and variable information, which is the ID type. You can get to this class type object through
