CLR Based PE (Portable Executable) Files

This section provides a tutorial example on how to use the .NET Intermediate Language disassembler to view PE headers and CLR headers of the executable files generated by the .NET C# compiler.

Once a CLR based PE file is opened in the .NET IL Disassembler, we can view its headers:

1. Open HelloCLR.exe in .NET IL Disassembler.

2. Click "Headers" > "View" in the menu. You will see headers of HelloCLR.exe displayed in a text window:

 ----- DOS Header:
 Magic:                      0x5a4d
 Bytes on last page:         0x0090
 Pages in file:              0x0003
 Relocations:                0x0000
 Size of header (paragraphs):0x0004
 ----- COFF/PE Headers:
 Signature:                  0x00004550
 ----- COFF Header:
 Machine:                    0x014c
 Number of sections:         0x0003
 Time-date stamp:            0x4cf95b45
 ----- PE Optional Header (32 bit):
 Magic:                          0x010b
 Major linker version:           0x08
 Minor linker version:           0x00
 Size of code:                   0x00000400
 ----- CLR Header:
 Header size:                        0x00000048
 Major runtime version:              0x0002
 Minor runtime version:              0x0005

The PE header and the CLR header shows that HelloCLR.exe is a PE file and requires CLR to execute.
