最近写了一个TCP读取SICK511传感器数据程序，vs代码在环境中直接运行没有问题，但运行debug文件下的exe，tcp读卡顿。仔细检查程序，发现程序逻辑没有问题，折腾了很长时间；附上未修改的代码：
主程序：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;
namespace ConsoleApplication10 { class Program { public static byte[] SICK_CMD_CONTINUE_MERSSURE = { 0x02, 0x73, 0x45, 0x4E, 0x20, 0x4C, 0x4D, 0x44, 0x73, 0x63, 0x61, 0x6E, 0x64, 0x61, 0x74, 0x61, 0x20, 0x31, 0x03 }; static void Main(string[] args) { Class1 cs = new Class1(); string temp = "";
while (true) { try { for (int i = 0; i < 400; i ) { temp = temp " " cs.databuffer[i].ToString(); } Console.WriteLine("帧数：" temp); temp = ""; Console.WriteLine(); } catch(Exception ex) { Console.WriteLine(ex.StackTrace.ToString()); } } }
} }
tcp连接类：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Net.Sockets; using System.Threading;
namespace ConsoleApplication10 {
class Class1 { public static byte[] SICK_CMD_CONTINUE_MERSSURE = { 0x02, 0x73, 0x45, 0x4E, 0x20, 0x4C, 0x4D, 0x44, 0x73, 0x63, 0x61, 0x6E, 0x64, 0x61, 0x74, 0x61, 0x20, 0x31, 0x03 };
public byte[] databuffer = new byte[400]; public string temp = "";
public TcpClient tc ; NetworkStream st; Thread a;
public Class1() { tc = new TcpClient("192.168.0.1", 2112); tc.ReceiveTimeout = 1000; st = tc.GetStream(); a = new Thread(new ThreadStart(func)); a.IsBackground = true; a.Start(); // st.Write(SICK_CMD_CONTINUE_MERSSURE, 0, 19); }
public void func() { st.Write(SICK_CMD_CONTINUE_MERSSURE, 0, SICK_CMD_CONTINUE_MERSSURE.Length); st.Read(databuffer, 0, 19); while (true) { Thread.Sleep(2); st.Read(databuffer, 0, 400); } }
} } 检查程序程序逻辑没有问题，考虑到传感器和电脑的速度匹配及响应时间，就试着增加延时，偶然间在获得网络数据流之后，加入延时10ms，解决问题；
tc = new TcpClient("192.168.0.1", 2112); tc.ReceiveTimeout = 1000; st = tc.GetStream(); Thread.Sleep(10);
从tcp获取数据流后，需要延迟
