c# - Proper error handling with windows service that loads external assembly/dll -

i have windows service loads bunch of 'plugins' .dll files. uses reflection this:

try {    assembly assembly = assembly.loadfile("myplugin.dll");    type[] types = assembly.gettypes();    foreach (type t in types)    {       type[] ifaces = t.getinterfaces();        foreach (type f in ifaces)       {           if (f.name == "myplugin")           {               ptype = t;               break;           }       }       if (ptype != null)           break;    } } catch {    addtolog("failed"); } obj = activator.createinstance(ptype);  object[] parameters = new object[1]; parameters[0] = _pluginname;  try {     ptype.invokemember("initializeplugin",                       bindingflags.default | bindingflags.invokemethod,                       null,                       obj,                       parameters);  } catch (exception ex) {     addtolog(_pluginname + " - initializeplugin error: " + ex.message); } 

problem having if 'initializeplugin' method external dll fails, not caught try/catch in code above , ends crashing whole service. there better way handle errors occur in externally loaded assembly this?

just use catch block no exception. not exceptions have type.

try {  } catch(exception ex) {  } catch { } { }
