聯(lián)網(wǎng)游戲的信息傳輸都是以字節(jié)流（字節(jié)數(shù)組）形式傳輸數(shù)據(jù)，本文展示基本數(shù)據(jù)類型與字節(jié)流互相轉(zhuǎn)換

girl模型有四個信息，GetByteNets方法將信息轉(zhuǎn)化為字節(jié)流，GetGirlFormNets()方法展示如何將字節(jié)流轉(zhuǎn)化為信息

using System;
public class Girl
{
    byte sex;
    short height;
    float weight;
    int age;
    public byte[] GetByteNets() //將這個對象轉(zhuǎn)化為字節(jié)流
    {
        //表示偏移量
        int offset = 0;
        //輸出的字節(jié)流
        byte[] result= new byte[11];
        //第一個字節(jié)放入數(shù)組
        result[0] = sex;
        offset++;
        //將身高參數(shù)轉(zhuǎn)化為字節(jié)流（short轉(zhuǎn)字節(jié)流）
        byte[] heightBytes = BitConverter.GetBytes(this.height);
        //字節(jié)流拷貝(源字節(jié)流，從第0個開始拷貝，目標字節(jié)流，拷貝到目標字節(jié)流第offset個，拷貝長度為原字節(jié)流長度)
        Buffer.BlockCopy(heightBytes,0,result,offset,heightBytes.Length);
        offset += heightBytes.Length;
        //將體重參數(shù)轉(zhuǎn)化為字節(jié)流
        byte[] weightBytes = BitConverter.GetBytes(this.weight);
        //字節(jié)流拷貝
        Buffer.BlockCopy(weightBytes, 0, result, offset, weightBytes.Length);
        offset += weightBytes.Length;
        //將年齡轉(zhuǎn)化為字節(jié)流
        byte[] ageBytes = BitConverter.GetBytes(this.age);
        //字節(jié)流拷貝
        Buffer.BlockCopy(ageBytes, 0, result, offset, ageBytes.Length);
        offset += ageBytes.Length;
        return result;
    }
    public Girl GetGirlFromNet(byte[] buffer)  //輸入字節(jié)流 輸出對象
    {
        Girl result = new Girl();
        result.sex = buffer[0];
        result.height = BitConverter.ToInt16(buffer, 1);
        result.weight = BitConverter.ToSingle(buffer, 3);
        result.age = BitConverter.ToInt32(buffer, 7);
        return result;
    }
}
