Common Intermediate Language (CIL)
CIL (Common Intermediate Language) is a bytecode
and the language of the .NET platform into which compiled source code of high
level language is written. Its operations are based on a stack and it is
executed by a virtual machine.
It is also called IL or MSIL (Microsoft Intermediate Language) which was its
original name before the standardization of the CLI (Common Language
Infrastructure) which he belongs and with which it should not be confused.
The source code from high-level language (C#, Basic or other language) is
compiled in CIL and stored into an assembly.
The assembly is stored in a file in the PE (Portable Executable) format, which
is also that of .dll and .exe, and includes a
manifest file containing the metadata of the assembly, which is the interface
of the code with other components of the software that uses it.
The CIL language
can execute operations in the following categories:
Logics and control (loop, if, etc.).
Calling functions and methods.
Loading and storing data.
Type converting (number into string...).
