<h1>前提</h1>
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。

如果觉得写的还行，请点个 star 支持一下吧

<h1>准备工作</h1>
该控件将继承基类控件UCControlBase，如果你还对UCControlBase不了解的下，
请移步 （一）c#Winform自定义控件-基类控件  查看
首先我们了解下要做的是什么，我们需要做一个可以自定义填充颜色，有圆角边框，有角标的按钮
<h1>开始</h1>
添加一个用户控件，命名为UCBtnExt ，继承 UCControlBase
先来看看我们按钮需要支持的属性吧
<div class="cnblogs_code">
<pre> 1 #region 字段属性
 2
 3 public bool IsShowTips
 4 {
 5 get
 6 {
 7 return this.lblTips.Visible;
 8 }
 9 set
10 {
11 this.lblTips.Visible = value;
12 }
13 }
14
15
16 public string TipsText
17 {
18 get
19 {
20 return this.lblTips.Text;
21 }
22 set
23 {
24 this.lblTips.Text = value;
25 }
26 }
27
28 private Color _btnBackColor = Color.White;
29
30 public Color BtnBackColor
31 {
32 get { return _btnBackColor; }
33 set
34 {
35 _btnBackColor = value;
36 this.BackColor = value;
37 }
38 }
39
40 private Color _btnForeColor = Color.Black;
41 /// <summary>
42 /// 按钮字体颜色
43 /// </summary>
44
45 public Color BtnForeColor
46 {
47 get { return _btnForeColor; }
48 set
49 {
50 _btnForeColor = value;
51 this.lbl.ForeColor = value;
52 }
53 }
54
55 private Font _btnFont = new System.Drawing.Font("微软雅黑", 12F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
56 /// <summary>
57 /// 按钮字体
58 /// </summary>
59
60 public Font BtnFont
61 {
62 get { return _btnFont; }
63 set
64 {
65 _btnFont = value;
66 this.lbl.Font = value;
67 }
68 }
69
70 /// <summary>

74 public event EventHandler BtnClick;

81 public string BtnText
82 {

84 set
85 {
86 _btnText = value;
87 lbl.Text = value;
88 }
89 }
90 #endregion</pre>
</div>
有了属性是不是就更明了呢
还有最后关键的一点东西，就是按钮的点击事件
<div class="cnblogs_code">
<pre>1 private void lbl_MouseDown(object sender, MouseEventArgs e)
2 {
3 if (this.BtnClick != null)
4 BtnClick(this, e);
5 }</pre>
</div>
至此基本上就完工了，下面列出了完整的代码
