How to view Intermediate Code in C# using Ildasm.Exe


How to view Intermediate Code in C# using Ildasm.Exe

Welcome to CodeSpread!

Hi guys, this is Sathish again, today let’s discuss how to view the intermediate code in c#.
We know that CLR (Common Language Runtime) is used to convert the MSIL (Microsoft Intermediate Language) which is a pseudo code, into an executable program when a program runs.
Knowing this, let’s discuss how to view MSIL using ILDASM.exe.

MSIL Disassembler

MSIL Disassembler is a companion tool to the MSIL Assembler (Ilasm.exe). Ildasm.exe takes a portable executable (PE) file that contains Microsoft intermediate language (MSIL) code and creates a text file suitable as input to Ilasm.exe.

This tool is automatically installed with Visual Studio and with the Windows SDK.

To run the tool, we recommend that you use the Visual Studio Command Prompt or the Windows SDK Command Prompt (CMD Shell).

This is the Program where it returns the no of objects created for a class

using System; 
using System.Collections.Generic;
using System.Linq; 
using System.Text;

namespace Chap1_3 
class Program 
static int count; public Program() 
static void Main(string[] args) 
Program p1 = new Program(); 
Program p2 = new Program(); 
Console.WriteLine("The No of Objects created for the class is : {0} ", count); 

// Output



Now let’s see what will be the Intermediate code for this program using ildasm.exe, and then go to following path
C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\ildasm.exe

If u open ildasm.exe It will pop up with a new Window, Then in a File menu choose open File, Then go to the debug folder and choose the .exe file of the project,the screen would look like below.



The Submenus defines the method, variables that are used within the program, to view the intermediate code of the function, just double click on it. This is the intermediate code for main function



Hope it helps you in checking the intermediate code of the program, Post your valuable comments to admin@codespread.com or at my personal id sathishkum1991@gmail.com
