您可以使用XamlReader.Parse创建ControlTemplate，然后简单地设置Button的属性

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;
