c# - Sending Sockets with binary and ascii data -

i trying integrate company , use sockets not familiar with

i can connected no problem having issues sending data based off want

they want call header record starts message length , 4 other fields integers , want in binary

then want message data want in ascii encoding

i can not figure out how im not sure if should use binary writer first part , try , add ascii

since byte[] dont think can altered after fact

can give me suggestions or samples think work me in matter

my suggestion first create message class "convertible" , byte[] type. can create netstream derives stream , use send data through specified socket. it's easy maintain solution not require additional knowledge socket communication @ all.
code example :

// include these namespaces : using system; using system.collections.generic;  public class message {     int m_messagelength;     // other fields     char m_otherfield1;     char m_otherfield2;     char m_otherfield3;     char m_otherfield4;     // message content assume string     string m_messagecontent;      public message(string message, int field1, int field2, int field3, int field4)     {         m_messageconten = message;         m_otherfield1 = field1;         m_otherfield2 = field2;         m_otherfield3 = field3;         m_otherfield4 = field4;     }      public static explicit operator byte[](this message message)     {         list<byte> buffer = new list<byte>();         // 4 fields each 2bytes wide gives 16 bytes         // ascii character 7 bits wide packed 8 bits 1byte         // gives result of ( length_of_message * 1byte == length_of_message )         buffer.addrange(bitconverter.getbytes(8 + m_messagecontent.length));         buffer.addrange(bitconverter.getbytes(m_otherfield1));         buffer.addrange(bitconverter.getbytes(m_otherfield2));         buffer.addrange(bitconverter.getbytes(m_otherfield3));         buffer.addrange(bitconverter.getbytes(m_otherfield4));         buffer.addrange(encoding.ascii.getbytes(m_messagecontent));         return buffer.toarray();     }  } 

having object can use socket.send method :

message message = new message("hello world", 1, 3, 3, 7); mesocket.send((byte[])message); 

if that's not enough let me know , i'll update answer more details.
