How does c# decompiler work

Can anybody tell me how this decompiler convert exe or dll files written in c# to its original source code?

There are two key points, here.

Firstly, IL, while a lower level language that C# or VB.NET, is a much higher level than assembler or machine code. Many high level constructs are still in place and can be used relatively easily to determine the flow and operation of the code.

The other key point, is that a decompiler does not generate the original source code. It generates high-level language constructs from the lower-level IL, which, typically are very similar to the original source code, but not identical.
