Question

I’m retrieving image from DB using Stream. Need someone to help me to convert to byte.
My code.

//connection.Open();

string sql = "SELECT Photo FROM ImageTable WHERE TagId = @ID";

SqlCommand cmd = new SqlCommand(sql, connection);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@ID", tagid);

connection.Open();

object img = cmd.ExecuteScalar();

try
{
    return new MemoryStream((byte[])img);
}
catch
{
    return null;
}

before I return I need to change to byte. Someone please help.

I don’t think this is what you really want, but since the question is how to convert MemoryStream to byte[]:

byte[] ObjectToByteArray(Object obj)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter b = new BinaryFormatter();
        b.Serialize(ms, obj);
        return ms.ToArray();
    }
}
