MemoryStream 比较怪异！ 见代码！
MemoryStream ms = new MemoryStream();
BinaryFormatter bf = new BinaryFormatter();

for (int i = 0; i < dt.Rows.Count; i++)
{
bf.Serialize(ms, dt.Rows[i][0]);
}
byte[] byteBuffer = new byte[ms.Length];
ms.Read(byteBuffer, 0, (int)ms.Length);

为什么byteBuffer中的值都是0呢，郁闷，怪，不懂

[解决办法]
#region SerializeToStream
public static Stream SerializeToStream(object obj)
{
Stream s = (Stream)(new MemoryStream());
SerializeToStream(s, obj);
return s;
}

public static void SerializeToStream(Stream s, object obj)
{
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(s, obj);
}
#endregion

ms拿完数据后,还要读就得 ms.Position = 0;
