问题描述

嗨



我是C＃的初学者。



我需要为temp创建表，电压和电流以及此数据库将通过串行通信定期更新。





我的查询是，如何在C＃窗口中创建表将动态更新数据的表单。我不想从任何数据库中提取数据。





请建议使用一些示例代码或控件？





谢谢

Hi

I am beginner to C#.

I need to create table for temp, voltage and current and this datab will be updating periodically by serial communication.


My query is, How to create a table in C# windows form which will update data dynamically. I do not want to extract data from any database.


Please suggest some sample code or controls to be used?


Thanks

推荐答案

你需要结合三个部分：



0）从串行通信中获取数据。如果您指的是RS232端口来读取数据，您可以使用 SerialPort课程 [ ^ ]。



1）您的数据模型。创建一个自定义类，其属性反映您要表示的数据。解码你从0）得到的东西并将数据输入你的模型。



一个简单的数据模型类：

You need to combine three parts:

0) Get the data from a serial communication. If you mean an RS232-port to read the data from, you can use the SerialPort class[^].

1) Your data model. Create a custom class with properties that reflect the data you want to represent. Decode what you got from 0) and feed the data into your model.

A simple data model class:

public class SingleDataPoint
{
    public decimal Temperature { get; set; }
    public decimal Voltage { get; set; }
    public decimal Current { get; set; }
}

这个类没有逻辑。它只是用于存储一些值。创建一个实例

This class has no logic in it. It''s just for storing some values. Create an instance

SingleDataPoint oneSingleData = new SingleDataPoint();

并填入值

oneSingleData.Temperature = -273.15;
oneSingleData.Voltage = 42;
oneSingleData.Current = 0x0815;

如果您需要丢失这些数据点，请将它们保存在BindingList<SingleDataPoint> [ ^ ]以便以后轻松绑定到您的UI。

2）显示数据。将您的模型绑定到 DataGridView [ ^ ]进行自动更新。

If you need losts of those data points, keep them in a BindingList<SingleDataPoint>[^] for later easy binding to your UI.
[/Edit]

2) Display the data. Bind your model to a DataGridView[^] for automatic updating.
