c# - Serializing the path of the running application -
good day,
i have client application sends server lists of application client opens. particulary sends file path, file name , hostname. problem sent data should serialize , deserialize when received in server. new c# have little idea of serialization.
this client side
private list<int> listedprocesses = new list<int>(); private void senddata() { string processid = ""; string processname = ""; string processpath = ""; string processfilename = ""; string processmachinename = ""; listbox1.beginupdate(); try { piis = getallprocessinfos(); (int = 0; < piis.count; i++) { try { if (!listedprocesses.contains(piis[i].id)) //placed on list avoid redundancy { listedprocesses.add(piis[i].id); processid = piis[i].id.tostring(); processname = piis[i].name.tostring(); processpath = piis[i].path.tostring(); processfilename = piis[i].filename.tostring(); processmachinename = piis[i].machinename.tostring(); output.text += "\n\nsent data : \n\t" + processfilename + "\n\t" + processmachinename + "\n\t" + processid + "\n\t" + processname + "\n\t" + processpath + "\n"; } } catch (exception ex) { wait.abort(); output.text += "error..... " + ex.stacktrace; } networkstream ns = tcpclnt.getstream(); string data = ""; data = "--++" + " " + processfilename + " " + processmachinename + " " + processid + " " + processpath; if (ns.canwrite) { byte[] bf = new asciiencoding().getbytes(data); ns.write(bf, 0, bf.length); ns.flush(); } } } { listbox1.endupdate(); } } private void cmd_dis_click(object sender, eventargs e) { if (wait != null) { wait.abort(); //read.close(2000); } ipaddress ipclient = dns.gethostbyname(dns.gethostname()).addresslist[0]; string ipclnt = "+@@+" + ipclient.tostring(); networkstream ns = tcpclnt.getstream(); if (ns.canwrite) { byte[] bf = new asciiencoding().getbytes(ipclnt); ns.write(bf, 0, bf.length); ns.flush(); } tcpclnt.close(); // read.close(); application.exit(); } private void listbox1_selectedindexchanged(object sender, eventargs e) { processinfoitem pii = piis.firstordefault(x => x.id == (int)(sender listbox).selectedvalue); if (pii != null) { string hostname = system.net.dns.gethostname(); textbox4.text = listbox1.selectedvalue.tostring(); textbox5.text = (pii.filename); textbox6.text = (pii.path); textbox7.text = (pii.machinename); } } private list<processinfoitem> piis = new list<processinfoitem>(); private void form1_load(object sender, eventargs e) { piis = getallprocessinfos(); listbox1.displaymember = "name"; listbox1.valuemember = "id"; listbox1.datasource = piis; } private list<processinfoitem> getallprocessinfos() { list<processinfoitem> result = new list<processinfoitem>(); process currentprocess = process.getcurrentprocess(); process[] processes = process.getprocesses(); foreach (process p in processes) { if (!string.isnullorempty(p.mainwindowtitle)) { //processinfoitem pii = new processinfoitem(p.id, p.mainmodule.modulename, p.mainmodule.filename, p.mainwindowtitle); processinfoitem pii = new processinfoitem(p.id, p.mainmodule.modulename, p.mainwindowtitle, p.mainmodule.filename, environment.machinename); result.add(pii); } } return result; } public class processinfoitem { public int id { get; set; } public string name { get; set; } public string filename { get; set; } public string path { get; set; } public string machinename { get; set; } public processinfoitem(int id, string name, string filename, string path, string machinename) { this.id = id; this.name = name; this.filename = filename; this.path = path; this.machinename = machinename; } } and here server needs deserialize
private void recievedata() { networkstream nstream = tcpclient.getstream(); asciiencoding ascii = null; while (!stoprecieving) { if (nstream.canread) { byte[] buffer = new byte[1024]; nstream.read(buffer, 0, buffer.length); ascii = new asciiencoding(); recvdt = ascii.getstring(buffer); /*received message checks if has +@@+ ip disconnected*/ bool f = false; f = recvdt.contains("+@@+"); if (f) { string d = "+@@+"; recvdt = recvdt.trimstart(d.tochararray()); clientdis(); stoprecieving = true; } //else if (recvdt.contains("^^")) //{ // new transmit_file().transfer_file(file, ipselected); //} /* ++-- shutsdown/restrt/logoff/abort*/ else if (recvdt.contains("++--")) { string d = "++--"; recvdt = recvdt.trimstart(d.tochararray()); this.invoke(new rcvdata(addtooutput)); clientdis(); } /*--++ normal msg*/ else if (recvdt.contains("--++")) { string d = "--++"; recvdt = recvdt.trimstart(d.tochararray()); this.invoke(new rcvdata(addtooutput)); } } thread.sleep(1000); } } public void addtooutput() { if (recvdt != null && recvdt != "") { output.text += "\n received data : " + recvdt; recvdt = null; } } thank you.
you can use wcf communication between client , server application.
you can create service , host in application receive data other application , consume service in other application send data , show response.
here example of doing in simple way. in sample have created 2 applications. application2 sends data application1 automatically once in each 10 secconds , application1 sends response application2 , application2 show response.
to run sample codes follow steps:
- create soloution 2 console applications, application1 , application2
- add system.servicemodel reference both projects.
- paste below codes in program.cs of each project.
- right click on solution , in properties, make solution multi startup projects , set action of each project 'start'
- press ctrl+f5 run projects
- in application1 window see service running message.
- application2 send datetime.now application 2 every 10 secconds , receive respone application 2 , display it application1 window.
application1 program.cs
using system; using system.servicemodel; namespace application1 { [servicecontract] public interface iechoservice { [operationcontract] string echo(string value); } public class echoservice : iechoservice { public string echo(string value) { return string.format("you send me data'{0}'", value); } } class program { static void main(string[] args) { using (servicehost host = new servicehost(typeof(echoservice), new uri[] { new uri("http://localhost:8000") })) { host.addserviceendpoint(typeof(iechoservice), new basichttpbinding(), "echo"); host.open(); console.writeline("service running..."); console.writeline("press enter exit if want close service."); console.readline(); host.close(); } } } } application2 program.cs
using system; using system.servicemodel; using system.servicemodel.channels; namespace application2 { [servicecontract] public interface iechoservice { [operationcontract] string echo(string value); } class program { static void main(string[] args) { //in real implementation, use server ip instead of localhost channelfactory<iechoservice> factory = new channelfactory<iechoservice>(new basichttpbinding(), new endpointaddress("http://localhost:8000/echo")); iechoservice proxy = factory.createchannel(); int processedseccond = 0; while (true) { var datetime = datetime.now; if (datetime.second % 10 == 0 && datetime.second!=processedseccond) { processedseccond = datetime.second; string data= datetime.tostring(); //or console readline manual data entry console.writeline("recieved response: " + proxy.echo(str)); } } } } } result
it's simple. can change codes desire.
an example of passing complex data service:
[datacontract] public class mymessageclass { [datamember] public string myvalue1 {get;set;} [datamember] public string myvalue2 {get;set;} } then can update interface , inplementation of service , use without need serialize , deserialize anything, things done wcf behind scene.
pleae note can use wcf services both windows forms applications , console applications , can continue develop project same way doing. change need add service application run on server , consume service in application run on client. not related logic of application all. , samples provided in console application sake of simplicity.
