मैं C # में एक संरचना को बाइट सरणी में कैसे बदलूं?
मैंने इस तरह एक संरचना को परिभाषित किया है:
public struct CIFSPacket
{
public uint protocolIdentifier; //The value must be "0xFF+'SMB'".
public byte command;
public byte errorClass;
public byte reserved;
public ushort error;
public byte flags;
//Here there are 14 bytes of data which is used differently among different dialects.
//I do want the flags2. However, so I'll try parsing them.
public ushort flags2;
public ushort treeId;
public ushort processId;
public ushort userId;
public ushort multiplexId;
//Trans request
public byte wordCount;//Count of parameter words defining the data portion of the packet.
//From here it might be undefined...
public int parametersStartIndex;
public ushort byteCount; //Buffer length
public int bufferStartIndex;
public string Buffer;
}
अपनी मुख्य विधि में, मैं इसका एक उदाहरण बनाता हूँ और इसे मान देता हूँ:
CIFSPacket packet = new CIFSPacket();
packet.protocolIdentifier = 0xff;
packet.command = (byte)CommandTypes.SMB_COM_NEGOTIATE;
packet.errorClass = 0xff;
packet.error = 0;
packet.flags = 0x00;
packet.flags2 = 0x0001;
packet.multiplexId = 22;
packet.wordCount = 0;
packet.byteCount = 119;
packet.Buffer = "NT LM 0.12";
अब मैं इस पैकेट को सॉकेट द्वारा भेजना चाहता हूं। उसके लिए, मुझे संरचना को बाइट सरणी में बदलने की आवश्यकता है। मैं यह कैसे कर सकता हूं?
मेरा पूरा कोड इस प्रकार है।
static void Main(string[] args)
{
Socket MyPing = new Socket(AddressFamily.InterNetwork,
SocketType.Stream , ProtocolType.Unspecified ) ;
MyPing.Connect("172.24.18.240", 139);
//Fake an IP Address so I can send with SendTo
IPAddress IP = new IPAddress(new byte[] { 172,24,18,240 });
IPEndPoint IPEP = new IPEndPoint(IP, 139);
//Local IP for Receiving
IPEndPoint Local = new IPEndPoint(IPAddress.Any, 0);
EndPoint EP = (EndPoint)Local;
CIFSPacket packet = new CIFSPacket();
packet.protocolIdentifier = 0xff;
packet.command = (byte)CommandTypes.SMB_COM_NEGOTIATE;
packet.errorClass = 0xff;
packet.error = 0;
packet.flags = 0x00;
packet.flags2 = 0x0001;
packet.multiplexId = 22;
packet.wordCount = 0;
packet.byteCount = 119;
packet.Buffer = "NT LM 0.12";
MyPing.SendTo(It takes byte array as parameter);
}
एक कोड स्निपेट क्या होगा?
