Loading referenced DLL's

[Patrick Ravi-Pinto]

Dear colleagues,
i'm new in the .net programming and hope you can help me.

I have two classes: Employee and Address
The Employee class has a reference to the Address and imports them on the
top.

I can test it locally, and it works but now I wants to load the Employee-DLL
with this code:

Public Function executeDllMetho d(ByVal DllPath As String, ByVal ClassName As
String, ByVal DLLMethod As String) As Object
Dim myAssembly As Assembly
myAssembly = Assembly.LoadFr om(DllPath)

Dim myMethod As MethodInfo
Dim myType As Type
myType = myAssembly.GetT ype(ClassName)
'MsgBox(DLLMeth od.ToString)
myMethod = myType.GetMetho d(DLLMethod)

Dim o As New Object
o = Activator.Creat eInstance(myTyp e)
Dim result As Object
result = myMethod.Invoke (o, Nothing)
Return result
But it does not work. I receive only an error, that the Address-DLL cannot
be loaded (File not found)
When I register the Address-DLL in the GAC it works.

Do you know a solution without using the GAC or where's/what's the problem?

Thanks
Patrick

Question, does DllPath contains full path to dll location?
FileNotFoundExc eption makes me think that there are no assembly on
<DllPath>.

<APPFOLDER> - application folder
<ASSEMBLY_NAM E> - assembly name
<CULTURE> - assembly culture info

You should place your assembly in <APPFOLDER> or
<APPFOLDER>\<AS SEMBLY_NAME> directory

if assembly has culture info then loader shall try to find it in the
following locations
<APPFOLDER>\<CU LTURE>
<APPFOLDER>\<AS SEMBLY_NAME>\<C ULTURE>

Try using the Assembly FullName

Es:

Dim testAssembly As AssemblyName =
System.Reflecti on.AssemblyName .GetAssemblyNam e(AssemblyName & ".dll")

asm = [Assembly].Load(testAssem bly.FullName)
