C#字节数组程序集

我希望能够组装/分解字节数据，如以下伪代码所示

//Step one, how do I WriteInt, WriteDouble, WritString, etc to a list of bytes?
List<byte> mybytes = new List<byte>();
BufferOfSomeSort bytes = DoSomethingMagical(mybytes);
bytes.WriteInt(100);
bytes.WriteInt(120);
bytes.WriteString("Hello");
bytes.WriteDouble("3.1459");
bytes.WriteInt(400);

byte[] newbytes = TotallyConvertListOfBytesToBytes(mybytes);

//Step two, how do I READ in the same manner?
BufferOfAnotherSort newbytes = DoSomethingMagicalInReverse(newbytes);
int a = newbytes.ReadInt();//Should be 100
int b = newbytes.ReadInt();//Should be 120
string c = newbytes.ReadString();//Should be Hello
double d = newbytes.ReadDouble();//Should be pi (3.1459 or so)
int e = newbytes.ReadInt();//Should be 400

我会在这里使用BinaryReader/BinaryWriter。

// MemoryStream can also take a byte array as parameter for the constructor
MemoryStream ms = new MemoryStream();
BinaryWriter writer = new BinaryWriter(ms);
writer.Write(45);
writer.Write(false);
ms.Seek(0, SeekOrigin.Begin);
BinaryReader reader = new BinaryReader(ms);
int myInt = reader.ReadInt32();
bool myBool = reader.ReadBoolean();
// You can export the memory stream to a byte array if you want
byte[] byteArray = ms.ToArray();

这让我想起了手动XML（反）序列化。如果你有一个可以序列化的对象，或者它只是你想写的"一堆项目"，你可能想使用二进制序列化？这里有一个链接，描述了您可以使用BinaryFormatter类和一个代码片段：

[Serializable]
public class DummyClass
{
    public int Int1;
    public int Int2;
    public string String1;
    public double Double1;
    public int Int3;
}
void BinarySerialization()
{
    MemoryStream m1 = new MemoryStream();
    BinaryFormatter bf1 = new BinaryFormatter();
    bf1.Serialize(m1, new DummyClass() { Int1=100,Int2=120,Int3=400,String1="Hello",Double1=3.1459});
    byte[] buf = m1.ToArray();
    BinaryFormatter bf2 = new BinaryFormatter();
    MemoryStream m2 = new MemoryStream(buf);
    DummyClass dummyClass = bf2.Deserialize(m2) as DummyClass;
}
