從沒有其他類創建噸的點列表構建PathGeometry

Question

我想從自定義的點列表中構建一個簡單的多邊形PathGeometry。我在msdn website上找到了下面的代碼，它看起來工作正常，對循環進行了一個簡單的修改並添加了LineSegments，但看起來像是一堆不合理的混亂，看起來是一個相對簡單的任務。有沒有更好的辦法？

PathFigure myPathFigure = new PathFigure(); 
myPathFigure.StartPoint = new Point(10, 50); 

LineSegment myLineSegment = new LineSegment(); 
myLineSegment.Point = new Point(200, 70); 

PathSegmentCollection myPathSegmentCollection = new PathSegmentCollection(); 
myPathSegmentCollection.Add(myLineSegment); 

myPathFigure.Segments = myPathSegmentCollection; 

PathFigureCollection myPathFigureCollection = new PathFigureCollection(); 
myPathFigureCollection.Add(myPathFigure); 

PathGeometry myPathGeometry = new PathGeometry(); 
myPathGeometry.Figures = myPathFigureCollection; 

Path myPath = new Path(); 
myPath.Stroke = Brushes.Black; 
myPath.StrokeThickness = 1; 
myPath.Data = myPathGeometry; 

Answer 1

您可以將其封裝在函數中，也可以合併一些語句。

Path makePath(params Point[] points) 
{ 
    Path path = new Path() 
    { 
     Stroke = Brushes.Black, 
     StrokeThickness = 1 
    }; 
    if (points.Length == 0) 
     return path; 

    PathSegmentCollection pathSegments = new PathSegmentCollection(); 
    for (int i = 1; i < points.Length; i++) 
     pathSegments.Add(new LineSegment(points[i], true)); 

    path.Data = new PathGeometry() 
    { 
     Figures = new PathFigureCollection() 
     { 
      new PathFigure() 
      { 
       StartPoint = points[0], 
       Segments = pathSegments 
      } 
     } 
    }; 
    return path; 
} 

然後，你可以這樣調用：

Path myPath = makePath(new Point(10, 50), new Point(200, 70));
