.net - TcpClient - how to determine when bytes are delivered? -

-

When using TcpClient, how do I know what the server is or is not found? For example, let's say my message is a long string: Prefix string myAppMessage = "long coding, bla, bla, bla, ....." byte [] allBytes = Encoding ASCII.GetBytes (myAppMessage);

And I want to completely close the string with TCP, and I want to know that the entire string was distributed and received by the server.

There are some common methods of sending data through TCP: 

  var client = new TCP client (IP_ADDR, PART) client. Gatestream () Type (all beta)  >    In the first case, do I call it on the stream after calling it  flush ()  Is given? I think one or both of the above calls are blocked. If it is complete without exception, can I understand that the whole message was received / received?   
 
 
 You need to get approval on the other side. Option:  
     
  1.  The remote party sends you an acknowledgment.  
  2.  Remote party  shutdown (read)  connection. Call  Read  until it returns 0. 0 signal that the remote side has closed and all the data has been received.  
  3.  Call Shutdown (Compose). It waits for acceptance from the remote side.   
     Sending alone does not guarantee delivery.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
