<h4>📚 转换原理说明</h4>
<p><strong>问题分析:</strong></p>
<p>你写入了5个int值[1,1,1,1,1],但读取时得到了10个ushort值[256,0,256,0,256,0,256,0,256,0]。这是因为:</p>
<ul>
<li>每个32位int被拆分成2个16位ushort读取</li>
<li>存在字节序转换问题</li>
<li>256 (0x0100) 表明原本的0x01字节被放在了高位</li>
</ul>
<div class="example">
原始int: 1 (0x00000001)
内存布局: [01][00][00][00] (小端序)
按ushort读取:
- 第1个ushort: [00][01] → 256
- 第2个ushort: [00][00] → 0
</div>
<p><strong>字节序说明:</strong></p>
<ul>
<li><strong>ABCD (大端序):</strong> 高字节在前,低字节在后</li>
<li><strong>DCBA (小端序):</strong> 低字节在前,高字节在后</li>
<li><strong>BADC/CDAB:</strong> 字节对调的混合模式</li>
</ul>
