入行已經7,8年了,一直想作一套漂亮點的自定義控件,因而就有了本系列文章。git

若是以爲寫的還行,請點個 star 支持一下吧編輯器

該控件將繼承基類控件UCControlBase,若是你還對UCControlBase不瞭解,請移步 (一)c#Winform自定義控件-基類控件 查看this
這個控件比較簡單,沒有多少東西,看下關鍵代碼吧url
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 MaxValue 18 { 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 }
而後看下完成代碼吧spa

用處:就是一個進度條
