Getting started with AMF

To explain how to use the package FluorineFx. AMF3 for AMF data, follow these steps.

FluorineFx. AMF3.ByteArray br = new FluorineFx. AMF3.ByteArray (new MemoryStream (bb); br. position = 0; br. readShort (); // amf version br. readShort (); // Number of headers br. readShort (); // number of bodies br. readUTFBytes (uint) (br. readShort (); // target length and string br. readUTFBytes (uint) (br. readShort (); // Response length and string br. readInt (); // body length br. readByte (); // body type object o = br. readObject ();

 

Use C # To simulate client requests and AMF request packets.
