Question

1. Hey, my question is simple but I can’t find a way to do this.

What I try to do is:
I try to get all the DLL Imports and the functions used from an EXE or DLL.

So let’s say I make a program with the: SendMessage (DLL Import)
Then the code would manage to read that.

And return like:

DLL: user32.dll

Function: SendMessage

I have tried using the: Assembly. But no luck getting correct data from it.

(I did look at: How to programatically read native DLL imports in C#?
But didn’t get it to work there either, I got 1 import, but nothing more)

A pure reflection approach

    static void Main(string[] args)
    {
        DumpExports(typeof (string).Assembly);
    }

    public static void DumpExports( Assembly assembly)
    {

        Dictionary<Type, List<MethodInfo>> exports = assembly.GetTypes()
            .SelectMany(type => type.GetMethods(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static)
                                    .Where(method => method.GetCustomAttributes(typeof (DllImportAttribute), false).Length > 0))
            .GroupBy(method => method.DeclaringType)
            .ToDictionary( item => item.Key, item => item.ToList())
            ;

        foreach( var item in exports )
        {
            Console.WriteLine(item.Key.FullName);

            foreach( var method in  item.Value )
            {
                DllImportAttribute attr = method.GetCustomAttributes(typeof (DllImportAttribute), false)[0] as DllImportAttribute;
                Console.WriteLine("\tDLL: {0}, Function: {1}", attr.Value, method.Name);
            }
        }
    }
