Examine IL Using ildasm.exe

In .Net , source is compiled to an Intermediate Language called Common Intermediate Language. This  IL is later compiled into native code at runtime, running in a virtual machine.

You can examine the IL of your application by a tool called IL Disassembler (ildasm.exe). You can find this tool (ildasm) in directory: C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin

Ildasm will show you three basic things of IL :-

• A list of all classes and methods in your assembly
• The contents of the assembly’s manifest
• IL code for any method implemented in the assembly.

 Here’s an example of what is displayed in ildasm.
