c# - Convert ICollection<Object> to another type ICollection<Person> using variable type of Type -


i try fill property type of icollection<person> or icollection<t> .i give objectlist type of list<object> or icollection<object> anyway can't set value property type of icollection<person> list of object

if (property.propertytype.isgenerictype &&      property.propertytype.getgenerictypedefinition()        == typeof(icollection<>))    {        type itemtype = property.propertytype.getgenericarguments()[0];       icollection<object> objectlist =getobjectlist();       property.setvalue(item, objectlist);      }

thanks.

you can't set icollection<person> icollection<object> since icollection isn't contravariant (there no in keyword in generic parameter declaration).

you explicitly have cast collection of object person

if (property.propertytype.isgenerictype &&  property.propertytype.getgenerictypedefinition()    == typeof(icollection<>)) {   type itemtype = property.propertytype.getgenericarguments()[0];   icollection<person> objectlist =getobjectlist().cast<icollection<person>>();   property.setvalue(item, objectlist); }
