wince 通信方式
wince通过gprs联网 ，通过socket或者是webservice和pc通信。web服务器端程序是其他人用java做的，发现无论是用socket还是webservice来通信服务器接收数据很慢都是同样的效果。然后我就把服务器端程序换成用C#做的窗体应用程序，并且开了个线程来不断的接收设备发来的数据。这样就能很快接收到数据了。
客户端程序：
public class ClassTongXin
{
public static int ServerPort;//服务器端口
public static string ServerIp;//服务器ip地址
public static TcpClient TcpClient = null;
public static IPAddress ServerAddress = null;
public string m_Error;//错误信息
///
/// 检查Server的地址是否存在
///
///
public bool GetServerAddress()
{
if (string.IsNullOrEmpty(ServerIp))
{
m_Error = "服务器不存在";
return false;
}
else
{
try
{
ServerAddress = IPAddress.Parse(ServerIp);
return true;
}
catch (Exception ex)
{
m_Error = "检查服务器异常：" + ex.Message;
return false;
}
}
}
///
/// 检查Server是否开启

///
public bool GetServerIsExist()
{
if (string.IsNullOrEmpty(ServerIp))
{
m_Error = "服务器不存在";
return false;
}
else
{
IPHostEntry remoteHost = null;
try
{
remoteHost = Dns.GetHostEntry(ServerIp);
return true;
}
catch (SocketException socketEx)
{
m_Error = "服务器未开启：" + socketEx.Message;
return false;
}
}
}
///

try

return msg;
}

public void Disconnect()

TcpClient.Close();
}
}
