Hello,
Sorry i don't know exactly where to post and sending to your mail.
I have an assembly "test.exe" and structure is like that , there are
some treeview example like reflexil , netdasm , but i already know
which type and method i have to delete and i got list of methods and
types to delete .
test.exe
Form1
Dispose
InitializeComponent
aa
dd
button1_Click
Form2
Dispose
InitializeComponent
aa
xx
button1_Click
Resources
Settings
get_Default
Program
Main
I am trying to delete Types and methods, to delete types i use
like that
TypeDefinition type =
assembly.MainModule.Types["test.Form1"];
assembly.MainModule.Types.Remove(type);
and it is ok ,but how do i delete method "test.Form1.aa" , i use this
way but no success
foreach (TypeDefinition type in assembly.MainModule.Types)
{
if (type.Name == "Form1")
{
foreach (MethodDefinition method in type.Methods)
{
if (method.Name == "bb")
{
type.Methods.Remove(method);
}
}
}
}
So can anybody advice how to delete methods and is there simple way to
delete like if i want to delete method "aa" of type "Form1" , just
give url of assembly like that
type.Methods.Remove("test.Form1.aa");
Many thanks

Please upgrade to Cecil 0.9.3.

You can solve that very easily with an extension method:
public static void RemoveMethod (this TypeDefinition self, string methodName)
{
var method = self.Methods.FirstOrDefault (m => m.Name == methodName);
if (method == null)
return;
self.Methods.Remove (method);
}
Note that this will delete the first method with the specified name,
and it's common to find methods with the same names.

Many thanks for reply, Sorry can you explain about
"FirstOrDefault" , i got error monocecil does not contain a definition
for "FirstOrDefault" , i use library from "http://anonsvn.mono-
project.com/source/trunk/mcs/class/Mono.Cecil/" or is there any
different build.
Thanks

I just gave you a link to the repository for Cecil 0.9:
http://github.com/jbevain/cecil
As for FirstOrDefault, it's a LINQ method:
http://msdn.microsoft.com/en-us/library/system.linq.enumerable.firstordefault.aspx
It requires .net 3.5 though.

Thank for you reply , i build the version from http://github.com/jbevain/cecil
, but there is no assemblyfactory definition so i can't load
AssemblyDefinition assembly =
Mono.Cecil.AssemblyFactory.GetAssembly("test.exe");
Any solution for that?
Thanks

Ok, finall done with this style coding
public static class Class1
{
public static void RemoveMethod(this TypeDefinition self,
string methodName)
{
var method = self.Methods.FirstOrDefault(m => m.Name ==
{
var asm =AssemblyDefinition.ReadAssembly("test.exe");
TypeDefinition type = asm.MainModule.Types[1];
Class1.RemoveMethod(type, "aa");
asm.Write(".exe");
}
But the problem i got is "asm.MainModule.Types[1];" , before cecil
library i could use "asm.MainModule.Types["Form1"]; , i mean i could
use string "Form1" , but now i have to find out first which one is
Types [1] or [0] or [2]. Please advise anyway i could use string like
before, as i have about 100 methods to delete.
Many thanks

You would have read the migration guide you would know. Use
ModuleDefinition.GetType(string).

Many thanks for your patient Evain , finally i sort it out, i will
read the migration guide and try other functions as well, if there is
out of my knowledge, i will start new thread.
Many thanks again

Hello Evain,
Sorry i got one simple question about one thing i have notice , from
the above assembly , by using this code
private void button2_Click(object sender, EventArgs e)
{
var asm = AssemblyDefinition.ReadAssembly("test.exe");
TypeDefinition type =
asm.MainModule.GetType("test.Form1");
asm.MainModule.Types.Remove(type);
asm.Write("ccc.exe");
}
I can delete type test.Form2, test.Program etc but why i cannot delete
Form1 , there is exception thrown nullreference when
asm.Write("ccc.exe"); , basically program is when button press form2
show. Similarly if there is
test
Form1
Form2
Form3
Form4 I cannot delete Form1/form2/form3 and only form4 i can
delete, Any idea?
Many thanks

Two things here.
First, Cecil should not throw a NullReferenceException, could you
paste the full stacktrace?
Second, it probably means that you're removing something blindly that
is used elsewhere.

Hello Evain,
Thanks for your info, today i have test about 7 EXE , they all the
same, and notice that we cannot delete these classes, so if you test
on any EXE with the code above , the result should be the same.

Sorry i want to be more clarify, as i said all about "i cannot delete"
means "i cannot save after delete these items using
"asm.Write("ccc.exe");"
Thanks

As I said, it's because you blindly remove a type while it's still
referenced somewhere in the assembly.

Hello Evan,
I have create new application , and in my application there is only
one button and only this code below , test on many assembly , so i
don't think it is still reference somewhere.
private void button1_Click(object sender, EventArgs e)
}
Thanks

{
var asm = AssemblyDefinition.ReadAssembly("test.exe");
TypeDefinition type =
asm.MainModule.GetType("test.Form1");
asm.MainModule.Types.Remove(type);
asm.Write("ccc.exe");
var asm = AssemblyDefinition.ReadAssembly("test.exe");
TypeDefinition type =
asm.MainModule.GetType("test.Form1");
asm.MainModule.Types.Remove(type);
}
Thanks
