C# Winform编程之Button

参考了这篇文章：

我的代码：

JButton.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Reflection;
namespace JiaYiControls
{
[DefaultEvent("Click")]
public partial class JButton : UserControl
{
private Image _normalImage = null;
private Image _hoverImage = null;
private Image _downImage = null;
public JButton()
{
_normalImage=Image.FromStream(Assembly.GetExecutingAssembly().GetManifestResourceStream(@"JiaYiControls.assert.button.normal.bmp"));
(_normalImage as Bitmap).MakeTransparent(Color.FromArgb(255, 0, 255));
_hoverImage = Image.FromStream(Assembly.GetExecutingAssembly().GetManifestResourceStream(@"JiaYiControls.assert.button.hover.bmp"));
(_hoverImage as Bitmap).MakeTransparent(Color.FromArgb(255, 0, 255));
_downImage = Image.FromStream(Assembly.GetExecutingAssembly().GetManifestResourceStream(@"JiaYiControls.assert.button.down.bmp"));
(_downImage as Bitmap).MakeTransparent(Color.FromArgb(255, 0, 255));
InitializeComponent();
this.BackgroundImage = _normalImage;
}
[Category("JiaYiControls")]
public Image NormalImage
{
get { return _normalImage; }
set { _normalImage = value; }
}
[Category("JiaYiControls")]
public Image HoverImage
{
get { return _hoverImage; }
set { _hoverImage = value; }
}
[Category("JiaYiControls")]
public Image DownImage
{
get { return _downImage; }
set { _downImage = value; }
}
[Category("JiaYiControls")]
public string Caption
{
get { return this.label1.Text; }
set { this.label1.Text = value; }
}
private void label1_Click(object sender, EventArgs e)
{
this.OnClick(e);
}
private void label1_MouseUp(object sender, MouseEventArgs e)
{
this.BackgroundImage = _normalImage;
}
private void label1_MouseDown(object sender, MouseEventArgs e)
{
this.BackgroundImage = _downImage;
}
private void label1_MouseHover(object sender, EventArgs e)
{
this.BackgroundImage = _hoverImage;
}
private void label1_MouseLeave(object sender, EventArgs e)
{
this.BackgroundImage = _normalImage;
}
}
}

设计器产生的代码：

namespace JiaYiControls
{
partial class JButton
{
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// 清理所有正在使用的资源。

/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
