CHAPTER 18 UNDERSTANDING CIL AND THE ROLE OF DYNAMIC ASSEMBLIES
}
}
Save your file to a convenient location (for example, C:\RoundTrip) and compile your program using
csc.exe, like so:
csc HelloProgram.cs
Now, open HelloProgram.exe with ildasm.exe and, using the File Dump menu option, save the raw
CIL code to a new *.il file (HelloProgram.il) in the same folder containing your compiled assembly (all
of the default values of the resulting dialog box are fine as is).
Note ildasm.exe will also generate a *.res file when dumping the contents of an assembly to file. These
resource files can be ignored (and deleted) throughout this chapter, as you will not be making use of them.
Now you are able to view HelloProgram.il using your text editor of choice. Here is the (slightly
reformatted and annotated) result:
// Referenced assemblies.
.assembly extern mscorlib
{
.publickeytoken = (B7 7A 5C 56 19 34 E0 89 )

// Our assembly.
.assembly HelloProgram
