System.Text.UnicodeEncoding
converter = new System.Text.UnicodeEncoding();
byte[]
inputBytes =converter.GetBytes(inputString);
string inputString
= converter.GetString(inputBytes);

string inputString
= System.Convert.ToBase64String(inputBytes);
byte[]
inputBytes = System.Convert.FromBase64String(inputString);
FileStream
fileStream = new FileStream(fileName,
FileMode.Open, FileAccess.Read, FileShare.Read);

将 Stream 转成 byte[]
public byte[]
StreamToBytes(Stream stream)
{
byte[]
bytes = new byte[stream.Length];
stream.Read(bytes,
0, bytes.Length);
stream.Seek(0,
SeekOrigin.Begin);
return bytes;
}

文件存储Dictionary或其它容器信息
public static int Save_Room_Information() //保存信息
{
FileStream fr = new FileStream("Room.bin", FileMode.OpenOrCreate);
BinaryFormatter st = new BinaryFormatter();
st.Serialize(fr, RoomInformation);
fr.Close();
return 1;
}
public static int Load_Room_Information() //载入信息
{
FileStream fr = new FileStream("Room.bin", FileMode.Open);
BinaryFormatter st = new BinaryFormatter();
RoomInformation = (Dictionary<int,List<Film>>)st.Deserialize(fr);
fr.close();
return 1;
}
