Declare a new object instance from an exist object instance

Question

I try to code a common method to fill in an class object list with datatable as following:

 

public static List FillDataTable(object obj, DataTable dt)

{

List objList = new List();

object o = new object(); //how to declare this instance based on the object obj???

foreach (DataRow dr in dt.Rows)

{

//code to fill datarow to the object o

objList.Add(o);

}

return objList;

}

 

Call this method as followiing:

 

List lstObj = new List();

lstObj = FillDataTable(((object)new myClass()), dt).OfType().ToList();
