Hi All, Lot of us have been asked this question in our interviews. So here are the
steps to create a multifile assembly using ".netmodules" .
Step 1:
1. Create a console application Named MultiFile1.
2. Add a class to this application named MyClass.
3. Remove the "Main" method from the class.
4. Add a new method to the class named "MultiFile1_Method"
5. Go to the visual studio command prompt, go to the directory where this class
resides.
6. Compile the class with this command : csc /t:module MyClass.cs
7. This is will create a file with extension ".netmodule" named
MyClass.netmodule.
Code :
using System;
namespace MultiFile1
{
class MyClass
{
public void MultiFile1_Method()
{
Console.WriteLine("This is a method from MultiFile1");
Console.ReadLine();
}
}
}
Step 2:
Add another class to the project named MyClient.cs Change the namespace
of the class from "Multifile1" to "MultiFile2" Add the reference to the
"MultiFile1" namespace. Add the main method to the class. Call the method
"MultiFile1_Method" of Myclass in the Main. Go to the visual studio command
prompt, go to the directory where this class resides. Compile the class with this
command : csc /addmodule:MyClass.netmodule /t:module MyClient.cs This is will
create a file with extension ".netmodule" named MyClient.netmodule. Code :
using System;
using MultiFile1; namespace MultiFile2
{ public class MyClient
{
public MyClient()
{
}
public static void Main()
{
MultiFile1.MyClass oMyClass = new MyClass();
oMyClass.MultiFile1_Method();
}
}
}
Step 3:
1. Go to the visual studio command prompt, go to the directory where these
classes reside
2. Create the assembly with the following command :
al MyClass.netmodule MyClient.netmodule
/main:MultiFile2.MyClient.Main /out:MyAssembly.exe /target:exe<o:p></o:p>
3. MyAssembly.exe will be created.
<o:p>4. O</o:p>pen the exe with ildasm and you will refernces to the two .netmodules
that we created .
MyAssembly opened in ildasm :
.module extern MyClient.netmodule
assembly extern mscorlib
{
.publickeytoken = (B7 7A 5C 56 19 34 E0 89 ) // .z\V.4..
.hash = (E6 8E F4 00 2B 3C 3C 88 D6 32 F2 72 A3 22 FA C8 // ...+<<..2.r."..
A7 7B 24 07 ) // .{$.
.ver 1:0:5000:0
}
assembly MyAssembly
{
// --- The following custom attribute is added automatically, do not uncomment
-------
// .custom instance void
[mscorlib]System.Diagnostics.DebuggableAttribute::.ctor(bool,
//
bool) = ( 01 00 00 01 00 00 )
.hash algorithm 0x00008004
.ver 0:0:0:0
}
file MyClass.netmodule
.hash = (92 EC 2F E8 F2 90 4B 2D 54 C6 AC 4C C5 69 CF 92 // ./...K-T..L.i..
37 2B A1 2F ) // 7+./
file MyClient.netmodule
.hash = (7B 4E 77 76 94 24 D9 3D 26 B4 3C 98 BA B1 49 3E // {Nwv.$.=&.<...I>
9C 45 90 0A ) // .E..
class extern public MultiFile2.MyClient
{
.file MyClient.netmodule
.class 0x02000002
}
module MyAssembly.exe
// MVID: {0B92C2A4-6956-4ED7-A40D-BAB2D6C505D4}
imagebase 0x00400000
subsystem 0x00000003
file alignment 512
corflags 0x00000001
// Image base: 0x071f0000
