您可以使用XamlReader.Parse創建的的ControlTemplate，然後簡單地設置屬性Button：

string xaml = "<ControlTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"><Polygon x:Name=\"poly\" Points=\"0,50 200,20 230,150 20,200\"><Polygon.Fill><ImageBrush x:Name=\"imgtem\" Stretch=\"Fill\" ImageSource=\"Images/67.png\"></ImageBrush></Polygon.Fill></Polygon></ControlTemplate>"; 
ControlTemplate template = System.Windows.Markup.XamlReader.Parse(xaml) as ControlTemplate; 

Button button = new Button(); 
button.Name = "btnNew"; 
button.Content = "Click me"; 
button.HorizontalAlignment = HorizontalAlignment.Left; 
button.Margin = new Thickness(54, 10, 0, 0); 
//... 
button.Template = template;
