美好的一天,
我有一个客户端应用程序,它向服务器发送客户端打开的应用程序列表。它特别发送文件路径,文件名和主机名。我的问题是发送的数据应该在服务器中收到时序列化和反序列化。我是C#的新手,所以我对序列化一无所知。
这是客户端
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();
for (int i = 0; i < piis.Count; i++)
{
try
{
if (!listedProcesses.Contains(piis[i].Id)) //placed this on a list to 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();
}
}
}
finally
{
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 as 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;
}
}
这里是需要反序列化的服务器
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 it has +@@+ then the ip is 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;
}
}
谢谢。

您可以使用WCF在客户端和服务器应用程序之间进行通信。
您可以创建服务并将其托管在将从其他应用程序接收数据的应用程序中,并使用其他应用程序中的服务来发送数据并显示响应。
以下是一个以简单方式执行此操作的示例。在这个示例中,我创建了2个应用程序。 Application2每10秒自动向Application1发送一次数据,Application1将响应发送回Application2,Application2将显示响应。
要运行示例代码,请按以下步骤操作:
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 is running...");
Console.WriteLine("Press Enter to exit if you want to 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 for manual data entry
Console.WriteLine("Recieved Response: " + proxy.Echo(str));
}
}
}
}
}
<强>结果强>
就这么简单。您可以根据自己的意愿更改代码。
将复杂数据传递给服务的示例:
[DataContract]
public class MyMessageClass
{
[DataMember]
public string MyValue1 {get;set;}
[DataMember]
public string MyValue2 {get;set;}
}
然后你可以更新界面和服务的实现,只需使用它而无需序列化和反序列化任何东西,所有的事情都将由WCF在幕后完成。
请注意,您可以将WCF服务与Windows窗体应用程序和控制台应用程序一起使用,并且可以继续以与您相同的方式开发项目。您需要的唯一更改是将服务添加到将在服务器上运行的应用程序,然后在将在客户端上运行的应用程序中使用该服务。它与您的应用程序的逻辑无关。为简单起见,我提供的样本在控制台应用程序中。
