AMF入门教程 (鬼蝶)

解释AMF数据可以采用FluorineFx.AMF3这个包，方法如下。

FluorineFx.AMF3.ByteArray br = new FluorineFx.AMF3.ByteArray(new MemoryStream(bb));   br.Position = 0;   br.ReadShort();//amf版本   br.ReadShort();//header数量   br.ReadShort();//body数量   br.ReadUTFBytes((uint)(br.ReadShort()));//target长度和字符串   br.ReadUTFBytes((uint)(br.ReadShort()));//Response长度和字符串   br.ReadInt();//body长度   br.ReadByte();//body类型   object o = br.ReadObject();

使用C# 模拟客户端请求，AMF请求 封包。
