clr.AddReferenceToFile(
AssemblyFilename
[, 
AssemblyFilename
...]
): Adds a reference 
to the .NET assembly by passing a filename. You may supply multiple filenames to load multiple 
assemblies. IronPython looks for the assembly using the 
sys.path
attribute. Consequently, you 
can partially control which version of the assembly you get by controlling the 
sys.path
attri-
bute. However, if more than one assembly has the correct filename, IronPython doesn’t guar-
antee which version of the assembly will load. You can use the 
clr.AddReferenceByName()
method to better control which version of the assembly loads.

clr.AddReferenceToFileAndPath(
AssemblyPathAndFilename
[, 
AssemblyPathAndFilename
 ...])
: Performs about the same task as the 
clr 
.AddReferenceToFile()
method. However, in this case, you must provide an absolute path 
to the assembly you want to load, which means that you have better control over which assem-
bly version loads. This method automatically adds the assembly path to 
sys.path
for you.

clr.AddReferenceByName(
AssemblyName
, Version=
VersionNumber
, Culture= 
CultureIdentifier
|neutral, PublicKeyToken=
TokenValue
)
: Adds an assembly refer-
ence based on assembly specifics normally found in the GAC. You must supply values that fully 
define the assembly. For example, to import the .NET Framework 2.0 version of the System.
Xml assembly, you would supply: 
‘System.Xml, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089‘
.
