How to use object as list of object - Array of object - How to create object in C#

   object input = new { Name ="yash"};

        input = 6;

        List<object> a = new List<object>();

        a.Add(5);

        a.Add( "ere");

object[] jji=new object[2]{ new {s = "df"}, new {s= "df"}};

some times we can use 

dr.ItemArray = new Object[] {new {    AgentName = "dfdf"}, new {AgentName = "df"} };
