在代码中绘制多个网格的最简洁的方法-C#WPF
本文关键字:简洁 方法 -C#WPF 网格 代码 绘制 | 更新日期: 2023-09-27 18:20:51
我需要使用C#WPF绘制用户定义数量的网格。我的代码可以工作,但如果允许的最大网格数很大,就会过长——有更简洁的方法吗?
以下代码显示了当前如何在gridCanvas(一个WPF网格控件)上绘制1个网格——对于可能需要的每个额外网格,都会重复该代码。
private void DrawInvGrid(int[,] initialPosn)
{
PathFigure myPathFigure1 = new PathFigure();
GeometryGroup myGeometryGroup1 = new GeometryGroup();
LineSegment myLineSegment1 = new LineSegment();
PathSegmentCollection myPathSegmentCollection1 = new PathSegmentCollection();
PathFigureCollection myPathFigureCollection1 = new PathFigureCollection();
// repeat declarations for each grid
int gridx = 5;
int gridy = 5;
int gridsize = 11;
// create grid 1
for (int z = 0; z < 5; z++)
{
int startpt_1x = (initialPosn[0, 0] - 5);
int startpt_1y = (initialPosn[0, 1] - 5);
for (int i = 0; i <= gridx; i++)
{
myPathFigure1 = new PathFigure();
myPathSegmentCollection1 = new PathSegmentCollection();
myPathFigure1.StartPoint = new System.Windows.Point(startpt_1x +
(i * gridsize), startpt_1y);
myLineSegment1 = new LineSegment();
myLineSegment1.Point = new System.Windows.Point(startpt_1x + (i * gridsize),
startpt_1y + gridy * gridsize);
myPathSegmentCollection1.Add(myLineSegment1);
myPathFigure1.Segments = myPathSegmentCollection1;
myPathFigureCollection1.Add(myPathFigure1);
xgridpos1.Add(startpt_1x + (i * gridsize));
}
for (int i = 0; i <= gridy; i++)
{
myPathFigure1 = new PathFigure();
myPathSegmentCollection1 = new PathSegmentCollection();
myPathFigure1.StartPoint = new System.Windows.Point(startpt_1x, startpt_1y +
(i * gridsize));
myLineSegment1 = new LineSegment();
myLineSegment1.Point = new System.Windows.Point(startpt_1x + gridx *
ridsize, startpt_1y + (i * gridsize));
myPathSegmentCollection1.Add(myLineSegment1);
myPathFigure1.Segments = myPathSegmentCollection1;
myPathFigureCollection1.Add(myPathFigure1);
ygridpos1.Add(startpt_1y + (i * gridsize));
}
}
// repeat grid creation loop for each grid
// display grid 1
gridCanvas.Children.Clear();
PathGeometry myPathGeometry1 = new PathGeometry();
myPathGeometry1.Figures = myPathFigureCollection1;
myPath1.Stroke = System.Windows.Media.Brushes.Green;
myPath1.StrokeThickness = 1;
myPath1.ToolTip = gridname;
myPath1.Data = myPathGeometry1;
gridCanvas.Children.Add(myPath1);
// repeat display routine for each grid
}
在任何特定的运行中,所有栅格都是相同的——只有栅格的位置(由int[,] initialPosn
定义)因栅格而异。欢迎就更有效的替代方案提出任何建议。
将重复代码提取到一个方法中,该方法只将那些改变的值(在您的情况下是位置)作为参数。
