Winform自定义控件—Button（上）

在开发中用的最多的相信就是Button控件，但是Button本身是在是太丑陋了，自己还背景图还会产生"黑线",为了使用方便，并且美观，我们采用迂回的方式来实现Button的效果。

在这里使用UserControl+Label进行封装

先来看代码:

ButtonM.cs

  1 using System;
  2 using System.ComponentModel;
  3 using System.Drawing;
  4 using System.Windows.Forms;
  5 
  6 namespace landptf.controls
  7 {
  8     public partial class ButtonM : UserControl
  9     {
 10 
 11         public ButtonM()
 12         {
 13             InitializeComponent();
 14         }
 15         /// <summary>
 16         /// 控件的默认图片
 17         /// </summary>
 18         private Image imageM = null;
 19         [Description("控件的默认图片")]
 20         public Image ImageM
 21         {
 22             get { return imageM; }
 23             set
 24             {
 25                 imageM = value;
 26                 label.Image = imageM;
 27             }
 28         }
 29         /// <summary>

 37             set { imageMove = value; }
 38         }

我们对外提供了设置背景图片，背景色，显示的文本，字体颜色，文本样式，点击事件。在开发中还会遇到其他需要的方法可自行完善。

明天我们在来看一下如何使用自定义控件
