Using DbLinq in IronPython - visual-studio-2010

Question

I'm trying to use dblinq in my IronPython application but am having some problems getting started. When trying to import dblinq classes,using clr.AddReference() it does not seem to see dblinq.
I can build but not access the library
import clr
clr.AddReference("DbLinq")
clr.AddReference("System.Data.Linq")
from System.Data.Linq import DataContext
exit = raw_input("press any key to quit")
1:
My dblinq source is in a subfolder called Resources
clr.AddReferenceToFileAndPath("Resources/DbLinq.dll") => file not found
clr.AddReference("DbLinq") => could not add reference to dblinq
clr.AddReferenceToFileAndPath("C:/Development/DBLinq2/Dblinq.dll" => success
but still cannot use the classes using from DbLinq import ...
Solution
import clr
clr.AddReferenceToFileAndPath("%s\Resources\DbLinq.dll" %os.getcwd())
clr.AddReference("DbLinq")
from Npgsql import *
from DbLinq import Data

For libraries like DbLinq that come with dependencies or are split into several DLLs/modules you can programmatically add their location to allow the runtime to find all required files.
import sys
sys.path.append(r"C:\Temp\DbLinq-0.20.1")
You can then reference all required assemblies as usual:
clr.AddReference("DbLinq")
If there is one primary assembly you can also use clr.AddReferenceToFileAndPath (with an absolute path) which will implicitly add the referenced assemblies location to the path.
clr.AddReference(r"C:\Temp\DbLinq-0.20.1\DbLinq.dll")
