Hello i have a question, can i convert an array of bytes to a my structure and vice versa? Thanx

byte[] ba = // Get data from somewhere.
YourStuct ys = new YourStuct();
using(MemoryStream ms = new MemoryStream(ba))
{
    BinaryReader br = new BinaryReader(ms);
    ys.SomeField = br.ReadByte();
    ys.SomeOtherField = br.ReadInt32();
    br.Close();
}

while (rdr.Read())<br />
{<br />
      Response.Write(rdr[0].ToString()); // rdr[0] refers to the first column in the resultset<br />
}

while (rdr.Read())<br />
{<br />
      Response.Write(rdr["TrainingCount"].ToString()); // no longer need to know which column number has the count - we refer by name<br />
}

// Boxing
ArrayList list = new ArrayList();
list.Add(1);
list.Add(2);
list.Add(3);
 
// No boxing
List<int> list = new List<int>();
list.Add(1);
list.Add(2);
list.Add(3);
