如何将计时器生成的数据保存到列表中。 [英] How would I save data generated from timer to list.

问题描述

float mag = ComputeDistance（Counter - 1，Counter - 2）;



richTextBox2.Text + =\ n物体与Radar的距离=+ mag .ToString（）+\ tObject Degree in Degree =+ ObjectAngle;



i想在列表中保存mag和ObjectAngle以便我可以使用它随时随地。

以上数据是每2秒使用一次计时器生成的。



我尝试过：

float mag = ComputeDistance(Counter - 1, Counter - 2);

richTextBox2.Text += "\n Object Distance from Radar=" + mag.ToString()+"\tObject Location in Degree=" +ObjectAngle;

i want to save "mag" and "ObjectAngle" in List so that i can use it whenever i want.
Above data is generating using timer every 2 second.

What I have tried:

List<dataanalyse> ObjectData = new List<dataanalyse>();     
struct DataAnalyse
         {
             public float Avgmag;
             public float AvgmagAngle; 

         }       

         
Public saveData()
{
DataAnalyse da=new DataAnalyse()
da.Avgmag=mag;
da.AvgmagAngle=ObjectAngle;
}

推荐答案

尝试稍微更改saveData：

Try just changing saveData slightly:

public saveData(float mag, float objAngle)
    {
    DataAnalyse da=new DataAnalyse();
    da.Avgmag=mag;
    da.AvgmagAngle=objAngle;
    ObjectData.Add(da);
    }

您还需要在ObjectData声明中正确获取案例 - C＃区分大小写，因此dataanalyse与DataAnalyse

You'll need to get the cases right on the ObjectData declaration as well - C# is case sensitive, so "dataanalyse" is not the same as "DataAnalyse"

据我所知，您的计时器将连续记录数据，您需要保留最后n个数据。

在这种情况下，列表效率不高，因为你不断添加新数据并删除最旧的数据。有一种称为循环缓冲区或FIFO缓冲区的结构更有效。

FIFO缓冲器实现 [ ^ ]

As I understand it, your timer will continuously record data, and you need to keep the last n data.
In this case, a list is not efficient, bacause you continuously add a new data and remove the oldest. There is a structure called "circular buffer" or "FIFO buffer" that more efficient.
