i'm writing application required utilize reflection phone call method has parameters of type myobject.

method (list<myobject> input , out list<myobject> output,..... );

using reflection send parameter of type object. how can cast list<myobject> list<object>

var parameters = new object[] { inputs, outputs, userprams }; system.type classtype = typeof(myclass); object instance = activator.createinstance(classtype); classtype.invokemember(name, bindingflags.invokemethod | bindingflags.instance | bindingflags.public,null, instance, parameters);

in code above both input , output lists of type myobject

i tried cast them list of objects doesn't work

x.outputs = groutputs ilist<object>

can help?

your question not 100% clear, assumed problem you're facing 1 set in title:

cast list of mytype list of objects

as @charles said, ilist<t> , list<t> not variant, can't cast ilist<derivedclass> ilist<baseclass>. have create new list<baseclass>.

there many ways that, think there 2 should consider:

you can utilize cast , tolist, require using system.linq.

var listofstrings = new list<string>() { "foo", "bar" }; var listofobjects = listofstrings.cast<object>().tolist();

to avoid that, can utilize new list<t>(ienumerable<t> source) constructor. because ienumerable<t> covariant, can following:

var listofstrings = new list<string>() { "foo", "bar" }; var listofobjects = new list<object>(listofstring);
