使用c#读取另一台计算机中的xml文件

Question

Sorry about my bad English. I have 2 computers, name "computer A" and "computer B", both are in a LAN. I have 2 projects. 1 at computer A and the other at computer B. Computer B has a "info.xml" file in project's bin folder. I want the project A could read that file using C#. Which method should i use? Thank you for taking your time. This is my "Computer A" code

namespace Client
{
    class Program
    {
        private const int BUFFER_SIZE = 1024;
        private const int PORT_NUMBER = 7826;
        public static string xmlsvinfo = Directory.GetCurrentDirectory() + "\\data\\serverinfo.xml";
        public static string xmlpath = Directory.GetCurrentDirectory() + "\\data\\gamesinfo.xml";

                Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

                // Console.ReadLine();

And here is "Computer B"

namespace Server

    class Program

                    Console.WriteLine("Client: " + command);
                    if (command.Equals("checkupdate"))

                        string dem = nodelist.Count.ToString();

I've tried to read my file in computer B then send it through socket. computer A will recieved it and write it to another xml file in computer A. but it won't work.

Here is also my "writexml" method

static void write_xml(string id, string name, string cata, string path)
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(xmlpath);

            XmlNode gameinfor = xmlDoc.CreateNode(XmlNodeType.Element, "gameinfor", null);

            XmlNode nodeId = xmlDoc.CreateElement("ID_Game");
            nodeId.InnerText = id;

            XmlNode nodegamename = xmlDoc.CreateElement("Tên_Game");
            nodegamename.InnerText = name;

            XmlNode nodetheloai = xmlDoc.CreateElement("Thể_Loại");
            nodetheloai.InnerText = cata;

            XmlNode nodegamepath = xmlDoc.CreateElement("Path");
            nodegamepath.InnerText = path;

            gameinfor.AppendChild(nodeId);
            gameinfor.AppendChild(nodegamename);
            gameinfor.AppendChild(nodetheloai);
            gameinfor.AppendChild(nodegamepath);

            xmlDoc.DocumentElement.AppendChild(gameinfor);
            xmlDoc.Save(xmlpath);

        }

If you only want a file to be read just read a file using the path of the file. There's no need to use sockets or so to do this. On the other hand, if you want to get some information from a computer to another I suggest using sockets.

Example of how to read a file in another computer (LAN) without sockets.

using (var file = File.Open("//server/path/file.txt")) {...}
