Search for interface in all assemblies of bin

Question

How can I scan all assemblies located in the bin directory and retrieve all types implementing an interface?

Answer 1

You can find them easily using Reflection and a LINQ query

var type = typeof(IRyuDice);
var types = AppDomain.CurrentDomain.GetAssemblies().ToList()
    .SelectMany(a => a.GetTypes())
    .Where(t => type.IsAssignableFrom(t));

AppDomain.CurrentDomain.GetAssemblies returns a System.Reflection.Assembly[] collection. Then you select all Types in that Assembly and check if your interface is used by that type.

Answer 2

My answer might be too obvious but I'll give it a shot...

You need to take a look at DirectoryInfo to get every file (*.dll) of the directory and the use reflection in order to digg into them...

Does that answer your question or do you want to know the actual implementation?
