在WPF中动态加载XAML中的控件实例代码

本文实例讲述了在WPF中动态加载XAML中的控件的方法。分享给大家供大家参考，具体如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.IO;
using System.Xml;
using System.Windows.Markup;

  /// <summary>
  /// Interaction logic for Window1.xaml

  public partial class Window1 : Window
  {
    public Window1()
    {
      InitializeComponent();
      //LoadEmbeddedXaml();
      //LoadEmbeddedXaml2();
      LoadEmbeddedXaml3();
    }
    //从字符串中加载
    public void LoadEmbeddedXaml()
    {
      Title = "Load Embedded Xaml";
      string strXaml = "<Button xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'" +
        " Foreground='LightSeaGreen' FontSize='16pt' Width='128' Height='32'>" +
        " From String Object!</Button>";
      StringReader strreader = new StringReader(strXaml);
      XmlTextReader xmlreader = new XmlTextReader(strreader);
      object obj = XamlReader.Load(xmlreader);
      grid1.Children.Add((UIElement)obj);
    }
    //从外部文件中加载 Button控件
    public void LoadEmbeddedXaml2()
    {
      XmlTextReader xmlreader = new XmlTextReader("d:\\a.xaml");
      UIElement obj = XamlReader.Load(xmlreader) as UIElement;
      grid1.Children.Add((UIElement)obj);
    }
    //从资源文件中加载
    public void LoadEmbeddedXaml3()
    {
      //Build Action = Resource,Do not Copy,无相应cs文件
      Uri uri = new Uri("/LoadXamlResource.xaml",UriKind.Relative);
      Stream stream =Application.GetResourceStream(uri).Stream;
      //FrameworkElement继承自UIElement
      FrameworkElement obj =XamlReader.Load(stream) as FrameworkElement;
      grid1.Children.Add(obj);
    }
  }
}

xaml文件中的清单

<Button xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'
  Foreground='LightSeaGreen'
  FontSize='16pt'
  Width='128'
  Height='32'>
  From File Object!
</Button>

希望本文所述对大家C#程序设计有所帮助。
