如何在C＃

Question

我很想编写一段有关如何使用C＃的代码。因此，对于真正的程序员来说，这可能是一个非常简单的问题。

我乱丢垃圾了。但是我过去一直在搜索，我只是对这里的问题感到好奇。如果有人能为我指出这一点，我会很高兴。正手谢谢！

       private void ButtonDraw_Click(object sender, RoutedEventArgs e)
        {
            SolidColorBrush color = new SolidColorBrush(Colors.White);

            MakeRectangle(drawingArea, color, 10, 20, 20);
            MakeRectangle(drawingArea, color, 10, 20, 40);
            MakeRectangle(drawingArea, color, 10, 20, 60);

        }

        private void MakeRectangle(Canvas drawing, SolidColorBrush brushcolor, double xPos, double yPos, double size)
        {
            Rectangle vierkant = new Rectangle();
            vierkant.Height = size;
            vierkant.Width = size;
            vierkant.Margin = new Thickness(xPos, yPos, 0, 0);
            vierkant.Stroke = brushcolor;
            drawing.Children.Add(MakeRectangle);

        }

Answer 1

您需要将vierkant Rectangle对象传递到drawing.Children.Add（）方法中，如下所示：

private void MakeRectangle(Canvas drawing, SolidColorBrush brushcolor, double xPos, double yPos, double size)
        {
            Rectangle vierkant = new Rectangle();
            vierkant.Height = size;
            vierkant.Width = size;
            vierkant.Margin = new Thickness(xPos, yPos, 0, 0);
            vierkant.Stroke = brushcolor;
            drawing.Children.Add(vierkant );

        }
