Dynamically Loading and calling a .net object

Is it possible to dynamically load then call a .net object. For instance, I have a exe and with this exe, I want to provide a folder that has a bunch of .net dlls with the same interface. I don't know the names of these dlls before the exe is compiled. I want to load all of the .net objects into memory and let the user select which ones to use.

Yes, I've also done this already.
Just use:
Type myType = Type.GetType("Full.Class.Name, AssemblyName");
Activator.CreateInstance(myType);
((IMyInterface)myType).MyMethod();

doesn't that assume that it is already loaded in the GAC? I am trying to load it from the dll.

Interesting project. ptmcomp's suggestion is close. You can read about the following and decide on what serves your purpose best:

Assembly.Load()
Assembly.LoadFrom()
Activator.CreateInstance()
Activator.CreateInstanceFrom()
Activator.CreateComInstanceFrom()

Have fun...

That's the code I used:
                  foreach (string typeName in typeNames)
                  {
                        Type type;
                        object dataSource;

                        type = Type.GetType(typeName);
                        if (type == null)
                        {
                              throw new ApplicationException(string.Format("Cannot load type '{0}'", typeName));
                        }
                        dataSource = Activator.CreateInstance(type);
                  }

This way there is no need to call Assembly.Load()
