c# 模拟led显示数字

前提

入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

GitHub：https://github.com/kwwwvagaa/NetWinformControl

码云：https://gitee.com/kwwwvagaa/net_winform_custom_control.git

如果觉得写的还行，请点个 star 支持一下吧

欢迎前来交流探讨：企鹅群568015492

麻烦博客下方点个【推荐】，谢谢

NuGet

Install-Package HZH_Controls

用处及效果

准备工作

使用GID+画的，不了解的话请自行百度

开始

添加一个类UCLEDNum ，继承UserControl

将数字拆分为单独的字，然后根据显示位置进行画出来，将显示位置定义为如下所示

复制代码


    /* 显示位置序号
     *  ****1***
     *  *      *  
     *  6      2
     *  *      *
     *  ****7***
     *  *      *
     *  5      3
     *  *      *
     *  ****4***
     */

复制代码

从上面可以看出，定义了1-7的位置，然后定义一个数字对应的显示列表

复制代码


 1  private static Dictionary<char, int[]> m_nums = new Dictionary<char, int[]>();
 2         static UCLEDNum()
 3         {
 4             m_nums['0'] = new int[] { 1, 2, 3, 4, 5, 6 };
 5             m_nums['1'] = new int[] { 2, 3 };
 6             m_nums['2'] = new int[] { 1, 2, 5, 4, 7 };
 7             m_nums['3'] = new int[] { 1, 2, 7, 3, 4 };
 8             m_nums['4'] = new int[] { 2, 3, 6, 7 };
 9             m_nums['5'] = new int[] { 1, 6, 7, 3, 4 };
10             m_nums['6'] = new int[] { 1, 6, 5, 4, 3, 7 };
11             m_nums['7'] = new int[] { 1, 2, 3 };
12             m_nums['8'] = new int[] { 1, 2, 3, 4, 5, 6, 7 };
13             m_nums['9'] = new int[] { 1, 2, 3, 4, 7, 6 };
14             m_nums['-'] = new int[] { 7 };
15             m_nums[':'] = new int[0];
16             m_nums['.'] = new int[0];
17         }

复制代码

你看到了还有“-”，“：”，“.”这3个符号，是为了时间和数字时候使用

然后定义一个矩形区域来用作绘画区域，并且在SizeChanged事件中赋值


Rectangle m_drawRect = Rectangle.Empty;
        void LEDNum_SizeChanged(object sender, EventArgs e)
        {
            m_drawRect = new Rectangle(1, 1, this.Width - 2, this.Height - 2);
        }

然后就是几个属性

复制代码


 1   private char m_value = '0';
 2 
 3         [Description("值"), Category("自定义")]
 4         public char Value
 5         {
 6             get { return m_value; }
 7             set
 8             {
 9                 if (!m_nums.ContainsKey(value))
10                 {
11                     return;
12                 }
13                 if (m_value != value)
14                 {
15                     m_value = value;
16                     Refresh();
17                 }
18             }
19         }
20 
21         private int m_lineWidth = 8;
22 
23         [Description("线宽度，为了更好的显示效果，请使用偶数"), Category("自定义")]
24         public int LineWidth
25         {
26             get { return m_lineWidth; }
27             set
28             {
29                 m_lineWidth = value;
30                 Refresh();
31             }
32         }
33 
34         [Description("颜色"), Category("自定义")]
35         public override System.Drawing.Color ForeColor
36         {
37             get
38             {
39                 return base.ForeColor;
40             }
41             set
42             {
43                 base.ForeColor = value;
44             }
45         }

复制代码

最重要的重绘

复制代码

  2         {
  3             base.OnPaint(e);
  4             e.Graphics.SetGDIHigh();

  8                 e.Graphics.FillRectangle(new SolidBrush(ForeColor), r2);
  9             }
 10             else if (m_value == ':')
