c# - Cant evaluate types of IList when looping properties -

i have class properties on it. call testmecommand (see below). class has list on it. need loop on properties of class, , identify list. has built generically because code validation, same code might need identify list<int> or list<string>, or else.

public class testmecommand {     [range(1, int32.maxvalue)]     public int theint { get; set; }      [required]     [stringlength(50)]     public string thestring { get; set; }      [listnotemptyvalidator]     public list<testlistitem> mylist { get; set; }      public class testlistitem     {         [range(1, int32.maxvalue)]         public int listint { get; set; }     } } 

now problem have code looks this:

foreach (var prop in this.gettype().getproperties()) {     if (prop.propertytype.fullname.startswith("system.collections.generic.list"))     {         ilist list = prop.getgetmethod().invoke(this, null) ilist;     } } 

i dont want put string in there, if prop.propertytype ilist never evaluates true. how fix it?

i might use:

if(typeof(ilist).isassignablefrom(prop.propertytype)) {...} 

which covers implementing ilist.

the reason prop.propertytype ilist never evaluates true asking "does type object implement ilist?", rather "does type represented type object implement ilist?".
