Hello.
I'm trying to figure out how to design a dll to trigger this code. My book didn't cover it so I don't know what to do.
| Code: | foreach (string f in Directory.GetFiles(System.Environment.CurrentDirectory, "addon-*.dll"))
{
Assembly asm = Assembly.LoadFile(f);
object[] descs = asm.GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);
AssemblyDescriptionAttribute desc = (AssemblyDescriptionAttribute)descs[0];
Console.WriteLine(desc.Description);
foreach (Type t in asm.GetTypes())
{
if (t.Name.EndsWith("Greeting"))
{
MethodInfo greet = t.GetMethod("Greet");
greet.Invoke(null, null);
break;
}
}
} |
Hmm.. So I need a class named greeting with a method called Greet? and the dll can be named addon-andsomerandomname.dll

You may need to use Assembly.LoadFrom instead of LoadFile.
Use the LoadFile method to load and examine assemblies that have the same identity, but are located in different paths. LoadFile does not load files into the LoadFrom context, and does not resolve dependencies using the load path, as the LoadFrom method does. LoadFile is useful in this limited scenario because LoadFrom cannot be used to load assemblies that have the same identities but different paths; it will load only the first such assembly.

| You should define an abstract base class that these plugins inherit from, and then check for the existence of this base class. It's quite a bit more stable when you do it this way (and has the advantage of providing a limited 'API' of sorts).
