GetValue和SetValue是在托管代码中直接获取或设置对象属性的一种方法,如下面例子:
<Rectangle x:Name="rect_MyRectangle" Width="100" Height="100" Fill="Blue"></Rectangle><TextBlock x:Name="txb_MyText2" />
C#代码:
public yufa2(){InitializeComponent();//利用GetValue和SetValuedouble left = 400;double top = 30;double radius = 10;string width;string height;//设置矩形的位置rect_MyRectangle.SetValue(Canvas.LeftProperty, left);rect_MyRectangle.SetValue(Canvas.TopProperty, top);//设置矩形的圆角度rect_MyRectangle.SetValue(Rectangle.RadiusXProperty, radius);rect_MyRectangle.SetValue(Rectangle.RadiusYProperty, radius);//获取矩形的宽和高width = rect_MyRectangle.GetValue(Rectangle.WidthProperty).ToString();height = rect_MyRectangle.GetValue(Rectangle.HeightProperty).ToString();//输出文本txb_MyText2.Text = "矩形的宽是:" + width + " 高是:" + height;txb_MyText2.SetValue(Canvas.LeftProperty, 400.00);}
设置存档属性?运行如图:
