C＃程序消耗高内存和CPU使用率 [英] C# program consuming high memory and cpu usage
本文介绍了C＃程序消耗高内存和CPU使用率的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
嗨。
我写了一个C＃应用程序。
程序包含一个从UDP套接字协议接收一些数据的线程（每个5毫秒）并在四个c＃图表上绘制它们！
当这个线程启动时，程序开始消耗高内存和CPU使用不幸！
我尝试过：
如果我使用ConcurrentQueue类，问题是解决了？
你对这个问题的建议对我有帮助！
注意：
我很抱歉我的英语不合适！
编辑：
我有一个帖子从这里开始：
Hi.
I have written a C# application.
the program contains a thread that receive some data from UDP socket protocol (each 5 ms) and plot them on four c# charts!
when this thread starts, the program starts consuming high memory and cpu usage unfortunately!
What I have tried:
if i use "ConcurrentQueue" Class, Will the issue be solved?
your suggestion about this problem will help me!
Note:
I'm sorry for my inappropriate English!
I have a thread that starts here:
thRcv = new System.Threading.Thread(rcvDP);
thRcv.Start();
线程方法：
the method of thread:
internal void rcvDP()
{
while (!(RobotStat == 0 | RobotStat == 1))
{
while (k_udpServer.Available > 0)
{
byte[] data = k_udpServer.Receive(ref ep_Server);
if (!LogData_flag && SaveFileEnded_Log)
{
//recive_Data_Form(data);
rcv_data_Form_Static(data);
}
else
{
rcv_Log_Data(data);
}
}
}
}
和 rcv_data_Form_Static是：
and the "rcv_data_Form_Static" is:
public void rcv_data_Form_Static(byte[] rcv_byte)
{
if (myFrmController.is_new_Trajectory)

my_Gait_Table.Time_Trajectory_Points = myFrmController.mGaitTable.Time_Trajectory_Points;

推荐答案
使用2个主题：
一个用于捕获数据;
另一个用于绘图读取捕获数据（来自数组或列表）。 />
更容易设计，构建和测试（独立）。
使用计时器绘图; 100ms是响应。
Use 2 threads:
One for "capturing" the data;
another for "plotting" that reads the "captured" data (from an array or list).
Easier to design, build and test (independently).
Use a timer to plot; 100ms is "responsive".
