c# - Instance of an abstract class not working -

i'm sure many of mark repeaed second see title. please bear me..facing complicated issue. :)

thanks reading till here :d

so, have class called infoclass, abstract-

public abstract class infoclass {     public abstract string brand { get; set; }     public abstract string brandcount { get; set; } } 

i have service in i'm making list out of it..and down line tryin make instance of same. not able to-

[webmethod]     public void getinfolist()     {         list<infoclass> listinformations = new list<infoclass>();         .         .         .      //going ahead in program i've created reader         .         .         .         .             while (rdr.read())             {                 //this block not working                 infoclass advertises = new infoclass();                 advertises.brand = convert.tostring(rdr["brand"]);                                 } 

please me out alternative code. i'm sure class meant abstract, cant change on class level.

i'm used more java, things seem similar c#.

abstract classes can't instanciated can see in documentation

they classes cannot instantiated, , either partially implemented, or not @ implemented.

thus new infoclass(); not valid. have either make infoclass not abstract, or create class inherits infoclass , instanciate it.
