Try this: using System; using System.Reflection; interface IPerson { string Name {get; set;} int Age {get; set;} } class Person : IPerson { public string Name {get; set;} public int Age {get; set;} public Person(string name int age) { Name = name; Age = age; } } class Program { static void Main() { Type pt = typeof(Person); Type[] args = new Type[]{typeof(string) typeof(int)}; ConstructorInfo ci = pt.GetConstructor(args); object[] args2 = new object[]{John 30}; IPerson ip = (IPerson)ci.Invoke(args2); Console.WriteLine(Name = {0} Age = {1} ip.Name ip.Age); Console.ReadKey(); } } The output is: Name = John Age = 30
