跟我学做C#皮肤美化之窗体换肤

　　CaculatePartLocation

　　在这个方法中就是根据当前窗体的width和height，再加上读取到的配置信息计算各个背景块的大小和位置。请注意方法中计算的顺序，先是左上角然后右上角最后中间。因为为了实现窗体的可缩放，中间的宽度是可变的。然后是左下方右下方，最后才是中间。中间的内容区域被我放了一个panel，其大小是可以变化的，具体的大小位置要看计算的结果。panel的另一个作用就是实现放在里面的控件的布局更好设置而不必关心上下两个边框。

private void CaculatePartLocation()
        {
            //顶部
            _topLeft.X = 0;
            _topLeft.Y = 0;

            _topRight.X = Width - _topRight.Width;
            _topRight.Y = 0;

            _topMiddle.X = _topLeft.Width;
            _topMiddle.Y = 0;
            _topMiddle.Width = Width - _topLeft.Width - _topRight.Width;

            //中间部分
            _centerLeft.X = 0;
            _centerLeft.Y = _topLeft.Height;
            _centerLeft.Height = Height - _topLeft.Height - _bottomLeft.Height;

            _centerRight.X = Width - _centerRight.Width;
            _centerRight.Y = _topRight.Height;
            _centerRight.Height = Height - _topLeft.Height - _bottomLeft.Height;

            _centerMiddle.X = _centerLeft.Width;
            _centerMiddle.Y = _topMiddle.Height;
            _centerMiddle.Width = Width - _centerLeft.Width - _centerRight.Width;
            _centerMiddle.Height = Height - _topMiddle.Height - _bottomMiddle.Height;

            //底部
            _bottomLeft.X = 0;
            _bottomLeft.Y = Height - _bottomLeft.Height;

            _bottomRight.X = Width - _bottomRight.Width;
            _bottomRight.Y = Height - _bottomRight.Height;

            _bottomMiddle.X = _bottomLeft.Width;
            _bottomMiddle.Y = Height - _bottomMiddle.Height;
            _bottomMiddle.Width = Width - _bottomLeft.Width - _bottomRight.Width;

            //按钮位置
            if (MaximizeBox && MinimizeBox)   // 允许最大化，最小化
            {
                maxButton.Left = Width - maxButton.Width - maxButton.XOffset;
                minButton.Left = Width - minButton.Width - minButton.XOffset;
                selectSkinButton.Left = Width - selectSkinButton.Width - selectSkinButton.XOffset;
            }
            if (MaximizeBox && !MinimizeBox)   //不允许最小化
            {
                maxButton.Left = Width - maxButton.Width - maxButton.XOffset;
                selectSkinButton.Left = Width - selectSkinButton.Width - minButton.XOffset;
                minButton.Top = -60;
            }
            if (!MaximizeBox && MinimizeBox)  //不允许最大化
            {
                maxButton.Top = -60;
                minButton.Left = Width - maxButton.XOffset - minButton.Width;
                selectSkinButton.Left = Width - selectSkinButton.Width - minButton.XOffset;
            }
            if (!MaximizeBox && !MinimizeBox)  //不允许最大化，最小化
            {
                minButton.Top = -60;
                maxButton.Top = -60;
                selectSkinButton.Left = Width - selectSkinButton.Width - maxButton.XOffset;
            }
            if (!_showSelectSkinButton)
            {
                selectSkinButton.Top = -60;
            }
            closeButton.Left = Width - closeButton.Width - closeButton.XOffset;

            //内容panel位置大小
              contentPanel.Top = _centerMiddle.Y;
            contentPanel.Left = _centerMiddle.X;
            contentPanel.Width = _centerMiddle.Width;
            contentPanel.Height = _centerMiddle.Height;

        }

　　ReadBitmap

　　这个方法是用来加载要使用皮肤的各个背景图片的，大家看代码就明白了，没什么好讲的。

private void ReadBitmap(string skinFolder)
        {
            //读取需要透明的颜色值
            int r = int.Parse(IniHelper.ReadIniValue(skinFolder + "\\config.ini", "Main", "TransparentColorR"));
            int g = int.Parse(IniHelper.ReadIniValue(skinFolder + "\\config.ini", "Main", "TransparentColorG"));
            int b = int.Parse(IniHelper.ReadIniValue(skinFolder + "\\config.ini", "Main", "TransparentColorB"));
            Color trans = Color.FromArgb(r, g, b);

            TransparencyKey = trans;   //透明处理

            _topLeft.BackgroundBitmap = Image.FromFile(skinFolder + "\\TopLeft.bmp") as Bitmap;
            _topMiddle.BackgroundBitmap = Image.FromFile(skinFolder + "\\TopMiddle.bmp") as Bitmap;
            _topRight.BackgroundBitmap = Image.FromFile(skinFolder + "\\TopRight.bmp") as Bitmap;

            _centerLeft.BackgroundBitmap = Image.FromFile(skinFolder + "\\MiddleLeft.bmp") as Bitmap;
            _centerMiddle.BackgroundBitmap = Image.FromFile(skinFolder + "\\Middle.bmp") as Bitmap;
            _centerRight.BackgroundBitmap = Image.FromFile(skinFolder + "\\MiddleRight.bmp") as Bitmap;

            _bottomLeft.BackgroundBitmap = Image.FromFile(skinFolder + "\\BottomLeft.bmp") as Bitmap;
            _bottomMiddle.BackgroundBitmap = Image.FromFile(skinFolder + "\\BottomMiddle.bmp") as Bitmap;
            _bottomRight.BackgroundBitmap = Image.FromFile(skinFolder + "\\BottomRight.bmp") as Bitmap;

            minButton.ReadButtonImage(skinFolder + "\\MinNormal.bmp", skinFolder + "\\MinMove.bmp", skinFolder + "\\MinDown.bmp");
            maxButton.ReadButtonImage(skinFolder + "\\MaxNormal.bmp", skinFolder + "\\MaxMove.bmp", skinFolder + "\\MaxDown.bmp");
            closeButton.ReadButtonImage(skinFolder + "\\CloseNormal.bmp", skinFolder + "\\CloseMove.bmp", skinFolder + "\\CloseDown.bmp");
            selectSkinButton.ReadButtonImage(skinFolder + "\\SelectSkinNormal.bmp", skinFolder + "\\SelectSkinMove.bmp", skinFolder + "\\SelectSkinDown.bmp");
        }
