WPF 体验对话框调用

很长时间没开博了。继续。。。。

WPF相对于Winform, dialog control是少了几个阿。不过都是一家子，可以必要时拿过来用用了。

做个简单程序调用个dialog。 效果图：

简单的调用，代码：

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;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }       

        public static string PicturePath = "";

        private void btnShow_Click(object sender, RoutedEventArgs e)
        {
            Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

            // Set filter for file extension and default file extension 

            dlg.DefaultExt = ".jpg";

            dlg.Filter = "JPEG Files (*.jpg)|*.jpg|PNG Files (*.png)|*.png|BMP Files (*.bmp)|*.bmp|All files (*.*)|*.*";



            // Display OpenFileDialog by calling ShowDialog method 

            Nullable<bool> result = dlg.ShowDialog();


            // Get the selected file name and display in a TextBox 

            if (result == true)
            {

                // Open document 

                string filename = dlg.FileName;

                PicturePath = filename;

            }

            
            this.image1.Source = GetImage();
            this.image1.Width = this.picPanel.Width;
            image1.Height = picPanel.Height;


        }

        private static BitmapImage GetImage()
        {
            BitmapImage image = new BitmapImage();
            image.BeginInit();
            image.UriSource = new Uri(PicturePath);
            image.EndInit();
            return image;
        }
       

        private void btnClear_Click(object sender, RoutedEventArgs e)
        {
            this.image1.Source = null;
        }

        private void btnSetBG_Click(object sender, RoutedEventArgs e)
        {
            System.Windows.Forms.ColorDialog color = new System.Windows.Forms.ColorDialog();
            if (color.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                this.picPanel.Background = new SolidColorBrush(Color.FromArgb(color.Color.A,color.Color.R,color.Color.G,color.Color.B));
            }
        }

        private void btnClose_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }

        
    }
}

别忘了引用system.windows.form噢！！

哦对了，这里有个Bug：拉伸窗体的时候只有最后一个Button拉伸变化，其它的不变。什么问题呢？ 待研究...
