is Stringbuilder using ArrayList ?

Hi,

 

?s stringbuilder using Arraylist?

 

http://neuromancer.i...rk-collections/

 

One main point to consider when using collections in a micro framework device is that of memory consumption. Each collection carries overhead — data that serves no other purpose than to facilitate the items you store in the collection. For example, inserting hundreds of items in an ArrayList will quickly use up most of the memory on a Netduino.


StreamReader vs FileStream

hi guys

 

i read this "StreamReader is a memory pig. Use FileStream directly." is this true. FileStream is light version of StreamReader.

 

thnx


WebAPI and Socket

21 February 2015 - 10:18 AM

hi guys

 

I can use  "Get or Post" method with simple socket connection. I can send any parameters via url to "Get or Post" method. But i cant use [formBody] property.

 

What is wrong?

            var xSocket = new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp);
            var xEndPoint = new System.Net.IPEndPoint(System.Net.Dns.GetHostEntry("127.0.0.1").AddressList[0], 80);

            xSocket.Connect(xEndPoint);
            xSocket.SetSocketOption(System.Net.Sockets.SocketOptionLevel.Tcp, System.Net.Sockets.SocketOptionName.NoDelay, true);
            xSocket.SendTimeout = 1000;

            //byte[] xContent = System.Text.Encoding.UTF8.GetBytes("this is content");

            string xRequestLine = "Get /api/My/45 HTTP/1.1\r\n";

            string xHeaderLines =
                "Host: localhost" + "\r\n" +
                "Accept: text/json; charset=utf-8" + "\r\n" +
                "Accept-Encoding: gzip, deflate" + "\r\n" +
                //"Content-Type: application/json" + "\r\n" +
                //"Transfer-Encoding: chunked" + "\r\n" +
                "Connection: Close" + "\r\n" +
                //"Content-Length: " + xContent.Length.ToString() + "\r\n" +
                "\r\n";     // EmptyLine

            xSocket.Send(System.Text.Encoding.UTF8.GetBytes(xRequestLine));
            xSocket.Send(System.Text.Encoding.UTF8.GetBytes(xHeaderLines));
            //xSocket.Send(xContent);
