怎样将List<PointF> pointsA转换为pointsA[]？？

Question

定义的list：
            List<PointF> pointsA = new List<PointF>();
            pointsA.Add(new PointF (1,1));
            pointsA.Add(new PointF (1,1.5F));
            pointsA.Add(new PointF (2,2));
            pointsA.Add(new PointF (3,4));
            pointsA.Add(new PointF (6,5.5F));
            pointsA.Add(new PointF (9,9));
画折线的函数：g.DrawLines(pen,this.pointsA);要求pointsA为point[]类，
求转换方法！有其他解决方法也可！谢谢！！

Answer 1

就调用这个方法吧 如果没有那你就是.net 2.0的版本 上面那个是linq的扩展方法 2.0没有

Answer 2

报错错误 CS0428: 无法将方法组“ToArray”转换为非委托类型“System.Drawing.PointF[]”。这个应该怎么处理?

Answer 3

List<string> pointsA = new List<string>();//随便用了个类型代替你的PointF
            pointsA.Add(string.Empty);
            pointsA.Add(string.Empty);
            var temp=pointsA.ToArray();//temp最后的类型是string[]
            Console.Read();

Answer 4

你还是默默的用foreach慢慢换吧

Answer 5

g.DrawLines(pen, this.pointsA.Select(x => new Point(x.X, x.Y)).ToArray());
