将Button XAML更改为C＃

Question

I have a tab control in which I am adding tab items programmatically. I want to have a close button with each tab item. On googling I found below XAML code for it:

<Button Content="X" Cursor="Hand" DockPanel.Dock="Right" 
        Focusable="False" FontFamily="Courier" FontSize="9" 
        FontWeight="Bold" Margin="5,0,0,0" Width="16" Height="16" />    

Now, I am converting this code into equivalent C# code and struggling with some of the properties. Below given is the code which I have till now.

var CloseButton = new Button()
{
     Content = "X",
     Focusable = false,
     FontFamily = FontFamily = new System.Windows.Media.FontFamily("Courier"),
     FontSize = 9,
     Margin = new Thickness(5, 0, 0, 0),
     Width = 16,
     Height = 16
};    

I want help with properties like Cursor, DockPanel.Dock. Any help on this is much appreciated. Thanks !

Cursors are a fairly standard set of types. There are static classes out there that give you access to many of them. Use the Cursors class to get the Hand .

DockPanel.Dock is an attached property, it's not a property of the button control. You have to use the property setters for that dependency object or other convenience methods if available.

var button = new Button
{
    Content = "X",
    Cursor = Cursors.Hand,
    Focusable = false,
    FontFamily = new FontFamily("Courier"),
    FontSize = 9,
    Margin = new Thickness(5, 0, 0, 0),
    Width = 16,
    Height = 16
};
// this is how the framework typically sets values on objects
button.SetValue(DockPanel.DockProperty, Dock.Right);
// or using the convenience method provided by the owning `DockPanel`
DockPanel.SetDock(button, Dock.Right);

Then to set the bindings, create the appropriate binding object and pass it to the element's SetBinding method:

button.SetBinding(Button.CommandProperty, new Binding("DataContext.CloseCommand")
{
    RelativeSource = new RelativeSource { AncestorType = typeof(TabControl) },
});
button.SetBinding(Button.CommandParameterProperty, new Binding("Header"));
