Getting Information About Object's Type

You can get the information of type of the any object by calling the GetType method of System.Object. Because every type in .Net inherits directly or indirectly from System.Object, every object will have access to the GetType method.

GetType returns an instance of a Type object, which can be queried to learn all about the type of the original object.

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.
