做了一个简单的示例,看效果:
或者有色块的网格:
以下是无色块的示例代码:
using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApp1.Forms.Csdn { public partial class Q7756354 : Form { readonly int rows = 10; readonly int cols = 10; float _cellWidth; float _cellHeight; private readonly Pen _pen = new Pen(Color.BurlyWood); public Q7756354() { InitializeComponent(); _cellWidth = (float)ClientSize.Width / cols; _cellHeight = (float)ClientSize.Height / rows; } private void Q7756354_Resize(object sender, System.EventArgs e) { _cellWidth = (float)ClientSize.Width / cols; _cellHeight = (float)ClientSize.Height / rows; Invalidate(); } private void Q7756354_Paint(object sender, PaintEventArgs e) { for (var row = 0; row < rows; row++) { var y = row * _cellHeight; var w = _cellWidth; for (var col = 0; col < cols; col++) { var x = col * _cellWidth; var h = _cellHeight; DrawRectangle(x, y, w, h); } } var g = e.Graphics; for (var i = 1; i < rows; i++) { g.DrawLine(_pen, 0, i * _cellHeight, ClientSize.Width, i * _cellHeight); } for (var i = 1; i < cols; i++) { g.DrawLine(_pen, i * _cellWidth, 0, i * _cellWidth, ClientSize.Height); } } private void DrawRectangle(float x, float y, float width, float height) { var brush = new SolidBrush(Color.DarkGray); var graphics = CreateGraphics(); graphics.FillRectangle(brush, new RectangleF(x, y, width, height)); brush.Dispose(); graphics.Dispose(); } } }
