                stud.roll = (int)rd[0];
                stud.name = (string) rd[1];
                stud.lname =(string) rd[2];

Try like this..

C#

while (rd.Read())
           {
            var   stud  = new Student();
               stud.roll = (int)rd[0];
               stud.name = (string) rd[1];
               stud.lname =(string) rd[2];

               list.Add(stud);
             
           }

 dataGridView1.DataSource = list;

sir thanks ,

sir can you provide some link or guide line to understand my fault.

see siddharth,
what you have done is , stud object (single) is created outside..
you are keep on over writing the object properties in the while loop, so off course it will be over written with the last value only..

now what i have mentioned is
creating a new instance in the while loop , so that the new object with new properties will be stored in the object and in the collection..
Got it???
