    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。

    准备工作

    该控件将继承基类控件UCControlBase,如果你还对UCControlBase不了解,请移步 (一)c#Winform自定义控件-基类控件 查看

    开始

    这个控件比较简单,没有多少东西,看下关键代码吧

     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 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         }

    然后看下完成代码吧
