ASM.Net是一个强大的工具，它允许开发者在.NET框架中使用汇编语言编写程序。尽管它目前并不能模拟所有的汇编指令，但已经实现了大量指令/操作码，足以满足大多数开发需求。此外，ASM.Net能够将编写的代码转换为字节数组，这些字节数组可以被ASM.Net再次读取以获取所有指令/变量/API。这意味着在ASM.Net中编写的代码是完全可移植的，可以在其他计算机上运行或处理，而无需担心任何问题。更重要的是，ASM.Net生成的字节数组在每个部分都是加密和压缩的，以防止代码被盗用。
要使用ASM.Net中的代码，需要具备一定的汇编语言知识，例如理解JMP、JNZ、CALL、XOR等指令。通过OpcodeWriter，可以编写代码、创建变量并执行更多操作。在编写完程序所需的所有内容后，还可以利用ASM.Net调试器进行调试，以确保一切按预期工作。
以下是一个示例代码，展示了如何使用ASM.Net编写一个消息框：
C#
OpcodeWriter writer = new OpcodeWriter();
// Call MessageBox
writer.codeSection.PUSH_VALUE(0);
// push a value to stack
ASM.Net creates a new variable and pushes the address of it to stack
writer.codeSection.PUSH_STRING("Title here");
writer.codeSection.PUSH_STRING("Hello CodeProject!");
writer.codeSection.PUSH_VALUE(0);
// push a value to stack
writer.codeSection.CALL(Functions.User32_MessageBoxA);
// call our MessageBox
AsmNet asmNet = new AsmNet(writer.Generate(true));
// initialize ASM.Net
Processor Cpu = asmNet.InitializeCPU();
// initialize the CPU to be able to execute our code
Cpu.RunLoop();
// execute the code we wrote
如所见，显示一个消息框的代码并不多。可能已经注意到，ASM.Net只需要一个字节数组作为参数。OpcodeWriter能够使用Generate函数将代码转换为字节数组。Generate函数的参数True用于在运行时检查每个JUMP地址是否有错误。这可以在与他人分享代码之前预防运行时错误。
当然，显示一个简单的消息框并不是ASM.Net的全部功能，它还能做更多。以下是一个简单的TCP服务器示例：
C#
OpcodeWriter writer = new OpcodeWriter();
WSAData wsaData = new WSAData();
sockaddr_in sockaddr = new sockaddr_in();
sockaddr_in Clientsockaddr = new sockaddr_in();
VirtualAddress wsaDataAddr = writer.dataSection.CreateVariable(wsaData);
VirtualAddress SockinAddress = writer.dataSection.CreateVariable(sockaddr);
VirtualAddress ClientSockinAddress = writer.dataSection.CreateVariable(Clientsockaddr);
VirtualAddress ArrayAddress = writer.dataSection.CreateVariable(ASCIIEncoding.ASCII.GetBytes(":)"));
// the data we want to send when a client connects
socket initialization
set the WSADATA settings
writer.codeSection.MOV_VARIABLE_VALUE(wsaDataAddr, "HighVersion", (ushort)2);
writer.codeSection.MOV_VARIABLE_VALUE(wsaDataAddr, "Version", (ushort)2);
set the sockaddr_in settings, setting the family IPv4
writer.codeSection.MOV_VARIABLE_VALUE(SockinAddress, "sin_family", (short)ValueCodes.InterNetworkv4);
setting port, we need to encode it first...
writer.codeSection.PUSH_VALUE(1337);
// 1337=listen port
writer.codeSection.CALL(Functions.ws2_32_htons);
writer.codeSection.MOV_VARIABLE_REGISTER(SockinAddress, "sin_port", Register.EAX);
writer.codeSection.PUSH_VARIABLE(wsaDataAddr);
writer.codeSection.PUSH_VALUE(36);
writer.codeSection.CALL(Functions.ws2_32_WSAStartup);
// started successfully ?
writer.codeSection.MOV_ECX(0);
writer.codeSection.CMP(CmpRegisterOpcodes.CMP_ECX_EAX);
writer.codeSection.JNE("failed");
create a socket
writer.codeSection.PUSH_VALUE(ValueCodes.Tcp, (int)0);
writer.codeSection.PUSH_VALUE(ValueCodes.Stream, (int)0);
writer.codeSection.PUSH_VALUE(ValueCodes.InterNetworkv4, (int)0);
writer.codeSection.CALL(Functions.ws2_32_socket);
// is socket > 0 ?
writer.codeSection.MOV_ECX((int)ValueCodes.INVALID_SOCKET);
writer.codeSection.CMP(CmpRegisterOpcodes.CMP_ECX_EAX);
writer.codeSection.JE("failed");
let's move our socket handle to EBX
writer.codeSection.MOV(MovRegisterOpcodes.MOV_EBX_EAX);
let's bind our socket
writer.codeSection.PUSH_VALUE(Marshal.SizeOf(sockaddr));
writer.codeSection.PUSH_VARIABLE(SockinAddress);
// our sockaddr_in
writer.codeSection.PUSH_EBX();
writer.codeSection.CALL(Functions.ws2_32_bind);
ok let's listen at a port
writer.codeSection.PUSH_VALUE((int)100);
writer.codeSection.PUSH_EBX();
writer.codeSection.CALL(Functions.ws2_32_listen);
now a infinite loop for accept our connections but let's setup our console
writer.codeSection.PUSH_VALUE(-11);
// STD_OUTPUT_HANDLE
writer.codeSection.CALL(Functions.Kernel32_GetStdHandle);
writer.codeSection.MOV(MovRegisterOpcodes.MOV_EDX_EAX);
writer.codeSection.CreateLabel("loop");
let's accept connections
writer.codeSection.PUSH_VALUE(Marshal.SizeOf(Clientsockaddr));
writer.codeSection.PUSH_VARIABLE(ClientSockinAddress);
writer.codeSection.PUSH_EBX();
// server socket
writer.codeSection.CALL(Functions.ws2_32_accept);
writer.codeSection.MOV(MovRegisterOpcodes.MOV_EDI_EAX);
// set client socket to EDI
writer.codeSection.PUSH_VALUE(0);
writer.codeSection.PUSH_VALUE(0);
writer.codeSection.PUSH_VALUE(20);
// char length
writer.codeSection.PUSH_STRING("new client accepted\r\n");
writer.codeSection.PUSH_EDX();
writer.codeSection.CALL(Functions.Kernel32_WriteConsoleA);
let's send a packet
writer.codeSection.PUSH_VALUE(0);
writer.codeSection.PUSH_VALUE(2);
writer.codeSection.PUSH_VARIABLE(ArrayAddress);
writer.codeSection.PUSH_EDI();
// client socket
writer.codeSection.CALL(Functions.ws2_32_send);
close our connection with the client...
writer.codeSection.PUSH_EDI();
writer.codeSection.CALL(Functions.ws2_32_closesocket);
writer.codeSection.JMP("loop");
writer.codeSection.PUSH_EBX();
writer.codeSection.CALL(Functions.ws2_32_closesocket);
writer.codeSection.CreateLabel("failed");
writer.codeSection.XOR(XorRegisterOpcodes.XOR_ECX_ECX);
这个示例展示了如何启动一个简单的TCP服务器，它接受连接并向连接者发送一个简单的笑脸表情。如所见，服务器正在等待新的连接。通过在Windows命令行中输入 "telnet 127.0.0.1 1337"，可以看到当按下回车键时，出现了一个笑脸表情。
调试过程中，ASM.Net提供了一些有用的功能，例如可以清楚地看到JUMP指令跳转到哪里。如果有任何问题，很乐意回答。但同时，也应该深入代码，了解其中的各种事件等。
