.Net Framework 3.0下的"Hello,World"

安装了Microsoft .NET Framework 3.0 Redistributable Package, 这东西我可是因为这里的破网速更新了6个小时,简直郁闷~在更新的时候就听了一些新的<老罗语录>简直太爽了,在"Orcas"的Next-Gen Development Tools发布之前我还是只能通过Visual Studio来开发.NET 3.0程序,Windows Vista应该会在月底发布,不过对硬件的要求的考虑我还是暂时不会升级,使用VS2005开发的时候必须安装Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF).

今天使用WPF写了一个很简单的程序但花了不少时间,对WPF这个开发框架和模式太不熟悉了,体会最深的一点就是代码和UI真正意义上的分离,或许这真的把OO发挥到了极致,XAML记录了UI的每一部分,而且这些代码都可以转化成C#代码,但反向则不是完全兼容.

Charles Petzold写的一本关于WPF的新书Applications = Code + Markup: A Guide to the Microsoft Windows Presentation Foundation (Pro - Developer) (Hardcover)上市了:

Orcas这东西可不要乱装,听粱老大说这个是一个虚拟镜像所以要用VPC运行,我们还是期待换新电脑后装预计在2007年发布的Orcas.

下面是我今天写的类似"Hello World"的WPF代码,在这里感谢程哥和粱老大的指导:
Window1.xaml.cs:

using System;
using System.Collections.Generic;
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.Shapes;

namespace WPFtest
{
    ///

    /// Interaction logic for Window1.xaml
    ///

    public partial class Window1 : System.Windows.Window
    {

        public Window1()
        {
            InitializeComponent();
            btn1.Click +=new RoutedEventHandler(btn1_Click);
        }
        public void btn1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("you waste time all the day");
            lbl1.Content = "Beauty:";

            // 创建一个源
            BitmapImage myBitmapImage = new BitmapImage();

            // BitmapImage.UriSource必须使用BeginInit/EndInit块
            myBitmapImage.BeginInit();
            myBitmapImage.UriSource = new Uri(@"e:/beauty.jpg");

            myBitmapImage.EndInit();
            //把源赋给Image控件
            img1.Source = myBitmapImage;

        }
    }
}

window1.xaml:

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="WPFtest" Height="442" Width="701"
    >
   
   
     
     
     
     
   
    Hello
   
   
 


代码就是以上的,下面是截图:
