前提
入行已經(jīng)7,8年了，一直想做一套漂亮點(diǎn)的自定義控件，于是就有了本系列文章。
開源地址：https://gitee.com/kwwwvagaa/net_winform_custom_control
<https://gitee.com/kwwwvagaa/net_winform_custom_control>
如果覺得寫的還行，請(qǐng)點(diǎn)個(gè) star 支持一下吧
歡迎前來交流探討： 企鵝群568015492? <https://shang.qq.com/wpa/qunwpa?

準(zhǔn)備工作
該控件將繼承基類控件UCControlBase，如果你還對(duì)UCControlBase不了解，請(qǐng)移步?（一）c#Winform自定義控件-基類控件

開始
這個(gè)控件比較簡單，沒有多少東西，看下關(guān)鍵代碼吧
1 private int _value = 0; 2 3 public int Value 4 { 5 get { return this
._value; } 6 set 7 { 8 if (value < 0) 9 return; 10 this._value = value; 11
SetValue();12 } 13 } 14 15 private int maxValue = 100; 16 17 public int
MaxValue18 { 19 get { return maxValue; } 20 set 21 { 22 if (value <= 0) 23
return; 24 maxValue = value; 25 SetValue(); 26 } 27 } 28 29 private void
SetValue()30 { 31 double dbl = (double)_value / (double)maxValue; 32 this
.panel1.Width = (int)(this.Width * dbl); 33 } 34 35 public ProcessExt() 36 {
37 InitializeComponent(); 38 } 39 40 private void ProcessExt_SizeChanged(
object sender, EventArgs e) 41 { 42 SetValue(); 43 } 44 45 public void Step()
46 { 47 Value++; 48 }
然后看下完成代碼吧
