Loading assemblies using Reflection when dependant dlls are missing.

Question

Hello All,
I've created a sample WinForms application where I upload a dll (present in my local machine).
I just need to read the public types (classes) defined in the assembly. So I've used the ExportedTypes property.
When the dependant dlls are present in my machine, I'm able to read the public types of the assembly using the ExportedTypes property.But when the dependant dlls are not available in my machine, I get the following error:
"Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."
Please let me know how to overcome this problem even when the dependant dlls are missing.
NOTE: When the same dll, is looked upon using  ILDASM.exe we are able to view its classes, even when the dependant dlls are not present.

Hi Darin,
Thanks again.!!
I'm having trouble reading a COM dll.
I'm using following code  and using the LoadTypeLib method to fetch the dlls ITypeLib.
[DllImport("oleaut32.dll", CharSet = CharSet.Unicode, PreserveSig = false)]
        static extern ITypeLib LoadTypeLib(string szFile);
I'm able to get the classes/ProgIds. But I need to fetch only those classes which implement a particular interface. I tried using the following code to fetch the implemented interface, but its not successful for the case where multiple classes implementing
that interface
var typeLibrary = LoadTypeLib(openFileDialog1.FileName);
int typeCount = typeLibrary.GetTypeInfoCount();
for (int i = 0; i < typeCount; i++)
System.Runtime.InteropServices.ComTypes.TYPEKIND TKind;
System.Runtime.InteropServices.ComTypes.IMPLTYPEFLAGS implInterface;
typeLibrary.GetTypeInfoType(i, out TKind);
if (TKind == System.Runtime.InteropServices.ComTypes.TYPEKIND.TKIND_COCLASS)
Type objType = typeLibrary.GetType();
Type objInterface = objType.GetInterface("IMyInterface", true);
try
 obj.GetImplTypeFlags(i, out Interfa);
