Get all used types

[Alex B]

Hellow,

Is there a way to get all types used inside C# method ie:

public int foo(string str)
{
Bar bar = new Bar();
string x = "test";
TEST t = bar.GetTEST();
}

would return: Bar, string and TEST.

There's no builtin way. See for instance:

Hellow, JB.

Try your advice (http://groups.google.com/group/mono-cecil/
browse_thread/thread/dfb05686e35cbcad/981d606149de1e99?
lnk=gst&q=used#981d606149de1e99)

This is test application:

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Class1 cl = new Class1();
Console.WriteLine(cl.Test());
}
}
}

Now I try to get all types in Main method:

var module = ModuleDefinition.ReadModule(fileName);
var type = module.Types.First(tt => tt.FullName ==
"ConsoleApplication1.Program");
var method = type.Methods.First(mm => mm.FullName == "System.Void
ConsoleApplication1.Program::Main(System.String[])");

foreach (var instruction in method.Body.Instructions)
{
if (instruction.OpCode.OperandType == OperandType.InlineType)
{
Console.WriteLine(instruction);
}
}

There are no instruction.OpCode.OperandType == OperandType.InlineType
What I do wrong?
The main task is to get all types used in assembly.

You don't have any direct type references in your test application.

If you check the IL, you'll notice that it looks something like this:

newobj void Class1::.ctor(void)

call string Class1::Test(void)

call System.Console.WriteLine(string)

All the operands are method references.

However, consider the following:

ldnull

castclass Class1

pop

Here the operand of the 'castclass' instruction is a TypeReference.

Hope it's clear now.
