新手们的GDI+绘制方格

//绘制panel控件触发的事件

//不可在窗体加载时绘制方格
        private void
panel1_Paint(object sender, PaintEventArgs
e)
       
{
            int
rowNum =
12;//行数
           
int colNum =
15;//列数；

           
Pen pen = new
Pen(Color.Black);//实例化一个“画笔”
           
Brush brushes = new
SolidBrush(Color.SkyBlue);//“画刷”
           
Graphics g =
Graphics.FromHwnd(this.panel1.Handle);//创建一个句柄

           
int width = this.panel1.Width /
colNum;//panel控件的宽度/列数==宽度
           
int height = this.panel1.Height /
rowNum;//panel控件的高度/行数==高度
           
int sideLength = width > height ? height :
width;//格子的边长

           
for (int rowIndex = 0; rowIndex < rowNum;
rowIndex++)//循环行数
           
{
               
for (int colIndex = 0; colIndex < colNum;
colIndex++)//循环列数
               
{
                   
g.DrawRectangle(pen, new Rectangle(colIndex * sideLength, rowIndex * sideLength,
sideLength,
sideLength));

                  
g.FillRectangle(brushes, new Rectangle(colIndex * sideLength + 1, rowIndex *
sideLength + 1, sideLength - 1, sideLength -
1));
               
}
           
}
        }

搞定收工，这些适合新手们的参考。希望可以帮到您！
