winform的主题实现没有bs里面那么舒服，下面做了一个简单实现，记录一下。
1、一个接口，需要做主题的控件、窗体都要实现这个接口
/// <summary>
/// 使用主题的控件、窗体需要实现此接口
/// </summary>
public interface ithemecontrol
{
itheme thistheme { get; set; }
/// <summary>
/// 重置主题
/// </summary>
void resettheme();
}
2、一个主题接口
/// <summary>
/// 主题
/// </summary>
public interface itheme
{
int code { get; }
/// <summary>
/// 初始化
/// </summary>
void init();
}
3、一个主题控制类
/// <summary>
/// 主题设置
/// </summary>
public class theme
{
internal delegate void checkedthemeeventhandle(itheme theme);
/// <summary>
/// 改变主题事件
/// </summary>
static internal event checkedthemeeventhandle checkedthemeevent;
static itheme currenttheme;
/// <summary>
/// 当前主题
/// </summary>
internal static itheme currenttheme
{
get { return currenttheme; }
set
{
if (value == null)
return;
currenttheme = value;
currenttheme.init();
if (checkedthemeevent != null)
{
checkedthemeevent(value);
}
}
}
/// <summary>
/// 加载控件的主题
/// </summary>
/// <param name="control"></param>
internal static void loadtheme(ithemecontrol control)
{
control.resettheme();
}
}
4、添加一个窗体通用的主题接口
public interface ithemebaseform
{
/// <summary>
/// 基本窗体背景色
/// </summary>
color baseformbackgroundcolor { get; }
/// <summary>
/// 基本窗体文字颜色
/// </summary>
color baseformforecolor { get; }
/// <summary>
/// 标题栏颜色
/// </summary>
color baseformtitlecolor { get; }
}
5、添加对应的窗体或控件的主题接口
窗体的样式接口（例子）
public interface ithemefrmlock : ithemebaseform
{
color frmlock_txtfillcolor { get; }
color frmlock_txtrectcolor { get; }
color frmlock_txtforecolor { get; }
color frmlock_btnfillcolor { get; }
color frmlock_btnforecolor { get; }
color frmlock_btnrectcolor { get; }
}
控件的样式接口（例子）
public interface ithemeucfileitem : itheme
{
color ucfileitem_backgroundcolor { get; }
color ucfileitem_forecolor { get; }
color ucfileitem_boxcolor { get; }
image ucfileitem_img1 { get; }
image ucfileitem_img2 { get; }
image ucfileitem_img3 { get; }
image ucfileitem_img4 { get; }
image ucfileitem_img5 { get; }
}
我这里做一个深色一个浅色主题
深色的
/// <summary>
/// 深色
/// </summary>
public partial class dark :
itheme,
ithemebaseform,
ithemefrmlock,
ithemeucfileitem
{
public int code { get { return 1; } }
/// <summary>
/// 基本窗体背景色
/// </summary>
public color baseformbackgroundcolor { get { return color.fromargb(37, 41, 59); } }
/// <summary>
/// 基本窗体文字颜色
/// </summary>
public color baseformforecolor { get { return color.white; } }
public color baseformtitlecolor { get { return color.fromargb(38, 45, 67); } }
/// <summary>
/// 初始化操作
/// </summary>
public void init()
{
//这里做一些修改主题时候的业务
}
#region 重写运算符
/// <summary>
/// 重写==
/// </summary>
/// <param name="lhs"></param>
/// <param name="rhs"></param>
/// <returns></returns>
public static bool operator ==(dark lhs, itheme rhs)
{
if (lhs == null && rhs == null)
return true;
else
{
if (lhs != null && rhs != null)
{
if (lhs.code == rhs.code)
return true;
else
return false;
}
else
return false;
}
}
/// <summary>
/// 重写!=
/// </summary>
/// <param name="lhs"></param>
/// <param name="rhs"></param>
/// <returns></returns>
public static bool operator !=(dark lhs, itheme rhs)
{
if (lhs == null && rhs == null)
return false;
else
{
if (lhs != null && rhs != null)
{
if (lhs.code == rhs.code)
return false;
else
return true;
}
else
return true;
}
}
public override bool equals(object obj)
{
if (obj == null || gettype() != obj.gettype())
{
return false;
}
if (obj is itheme)
{
if (code == ((itheme)obj).code)
return true;
else
return false;
}
else
{
return false;
}
}
public override int gethashcode()
{
return base.gethashcode();
}
#endregion
}
浅色的也一样 只需要实现
- itheme,
- ithemebaseform,
- ithemefrmlock,
- ithemeucfileitem
这些接口就行（定义的控件接口，这里都要进行实现）
然后添加具体的控件主题实现类
/// <summary>
/// frmlock
/// </summary>
public partial class dark
{
public color frmlock_txtfillcolor { get { return color.fromargb(34, 40, 60); } }
public color frmlock_txtrectcolor { get { return color.fromargb(65, 75, 101); } }
public color frmlock_txtforecolor { get { return color.white; } }
public color frmlock_btnfillcolor { get { return color.fromargb(46, 54, 76); } }
public color frmlock_btnforecolor { get { return color.fromargb(175, 193, 225); } }
public color frmlock_btnrectcolor { get { return color.fromargb(65, 75, 101); } }
}
然后就是去控件或窗体里面做事情了，实现接口theme.ithemecontrol，构造函数里面添加checkedthemeevent事件
public partial class frmlock : frmwithtitle,theme.ithemecontrol
{
public frmlock()
{
try
{
initializecomponent();
theme.theme.checkedthemeevent += theme_checkedthemeevent;
}
catch (exception ex)
{
}
}
void theme_checkedthemeevent(theme.itheme theme)
{
if (this.visible)
{
thistheme = theme;
}
}
visiblechanged事件添加内容
private void frmlock_visiblechanged(object sender, eventargs e)
{
if (visible)
{
thistheme = theme.theme.currenttheme;
}
}
实现的接口
theme.itheme thistheme = null;
/// <summary>
/// 当前页面正在使用的主题
/// </summary>
public theme.itheme thistheme
{
get
{
if (thistheme == null)
{
thistheme = theme.theme.currenttheme;
}
return thistheme;
}
set
{
if (thistheme != value)
{
thistheme = value;
theme.theme.loadtheme(this);
}
}
}
public void resettheme()
{
var t = (theme.ithemefrmlock)thistheme;
this.backcolor = t.baseformbackgroundcolor;
this.lbltitle.backcolor = t.baseformtitlecolor;
this.lbltitle.forecolor = t.baseformforecolor;
uccontrolbase1.fillcolor = t.frmlock_txtfillcolor;
uccontrolbase1.rectcolor = t.frmlock_txtrectcolor;
txtpw.backcolor = t.frmlock_txtfillcolor;
txtpw.forecolor = t.frmlock_txtforecolor;
tongyong_btnpaizhaopath.fillcolor = t.frmlock_btnfillcolor;
tongyong_btnpaizhaopath.rectcolor = t.frmlock_btnrectcolor;
tongyong_btnpaizhaopath.forecolor = t.frmlock_btnforecolor;
}
以上就是修改代码，下面看调用
theme.theme.currenttheme = new theme.dark();
效果
