Assembly load error;

Question

When I try to load the assembly into a separate Application domain, I get an exception.

Here is my code:

C#

domain = AppDomain.CreateDomain("MyDomain");
mi = default(MethodInfo);

Assembly a = domain.Load(path); //Exception thrown here

Type type = a.GetType(nameSpace.ClassName);

mi = type.GetMethod("Greeting");
Console.WriteLine(mi.Invoke(null, new object[] { "Ryan" }).ToString())

I get the following exception when trying domain.load:

Could not load file or assembly 'C:\\temp\\good.dll' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

I have verified that the file exists within the location, and it is there.

Does anybody know what this problem might be?

Look here:
MSDN: AppDomain.Load Method[^]

It does not take assembly path as a parameter. The way you define, it is trying to find an assembly that has name 'C:\temp\good.dll'. This is wrong.

Try:

C#

string fileToLoad = @"C:\temp\good.dll";
AssemblyName assamblyName = AssemblyName.GetAssemblyName(fileToLoad);
AppDomain myDomain = AppDomain.CreateDomain("MyDomain");                   
Assembly myAssambly = myDomain.Load(assamblyName);
