Question

这里我有一个标签的XAML，但我想用C＃定义它。

任何人都可以帮我翻译成C＃所以我可以在运行时创建这个标签吗？

它所在的画布名为left_canvas。

<Label Canvas.Left="10" Canvas.Top="10" Canvas.Right="10" Height="30" Width="280"  
       Name="classname_label" FontFamily="MS Reference Sans Serif" FontSize="16"
       FontWeight="Bold" Foreground="#FF3535A0" Content="Physics 101" />

Answer 1

你需要这样的东西

Label label1 = new Label();
label1.Content = "Physics 101";
label1.Width = 280;
label1.Height = 30;
label1.SetValue(Canvas.LeftProperty, 10.0);
left_canvas.Children.Add(label1);

Answer 2

你去吧。希望这个Helps.Working和Tested

            BrushConverter bc = new BrushConverter();
            Label classname_label = new Label();
            classname_label.Content = "Physics 101";
            classname_label.Foreground = (Brush)bc.ConvertFrom("#FF3535A0");
            Canvas.SetLeft(classname_label, 10);
            Canvas.SetTop(classname_label, 10);
            Canvas.SetRight(classname_label, 10);
            classname_label.Height=30;
            classname_label.Width=280;
            classname_label.FontFamily =new System.Windows.Media.FontFamily("MS Reference Sans Serif");
            classname_label.FontSize=16;
            classname_label.FontWeight = System.Windows.FontWeights.Bold;
            //Control you want to contain label 
            left_canvas.Controls.Add(classname_label);

Answer 3

您可以创建一个新的Label实例，只需设置您列出的所有属性。

Label label = new Label();

label.Height = new Unit(30, UnitType.Pixel);
...
label.Content = "Physics 101";

//Set the dependency properties.
label.SetValue(Canvas.Left, 10);
...
label.SetValue(Canvas.Top, 10);

//Add it to the canvas.
left_canvas.Controls.Add(label);

或者那种效果，属性名称和依赖项属性名称可能不准确，因为它来自内存。

如何动态定义此标签？
