i working on project need queue number of property changes. let have: public class foo { string bar { get; set; } int bar1 { get; set } } i want have code looks like: //store value set actions in queue foo.setvalue(bar, "abc"); foo.setvalue(bar1, 123); //preview changes foreach(item change in foo.changequeue) { console.write(change.propertyname.tostring()); console.write(change.value.tostring()); } //apply actions foo.commitchanges(); what best way accomplish this? "type-safe" version uses callbacks. not automatically remove duplicate-settings. not use reflection , property-name errors fail on compilation. method expanded require "name" , remove duplicates using dictionary backing (as per akash's answer) or allow "setter" return value (such success or failure or old value, or whatnot). interface setter { void apply(); } class setter<t> : setter { public t data; public action<t> setf...
