Adding references dynamically in .NET

Question

I have two dll's (sqlite) , one dll is a 64 bit and other 32 bit dll. Is it possible to add reference dynamically based on processor architecture? P/Invoke is my last option. Any help would be appreciated!!

Sample Code:

string pathToDll = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + "\\x64\\System.Data.SQLite.dll";
Assembly assembly = Assembly.LoadFrom(pathToDll);
AppDomain.CurrentDomain.Load(assembly.GetName());

One may want to compile to Any architecture and run on both 32/64. Of course you can solve this by good installer, but this may not be a duplicate — wiero, Oct 16 '13 at 08:49

Yes, you can load assembly from a file

 Assembly.LoadFrom("MyAssembly.dll");

from .net4 you may use Is64BitOperatingSystem Environment property. Otherwise check IntPtr.Size which changes according to running architecture

How will I use the dll methods,since I will be dynamically adding reference? – Aster Veigas Oct 16 '13 at 08:45

I read about the assembly.loadfrom method. It looks like the real deal, I'll confirm the solution tomorrow – Aster Veigas Oct 16 '13 at 19:25
I tried assembly.loadfrom method. It gets loaded but VS still throws exception. It still thinks that the file is x86 (on x64 machine) – Aster Veigas Oct 18 '13 at 10:22

A quick question, can I fake the System.Data.SQLite namespace to the compiler? – Aster Veigas Oct 18 '13 at 11:28
