如何从C＃中的代码后面显示PictureBox

Question

我知道我的问题听起来很基本，但是我到处搜索，却一无所获..这是我的代码：

public MainWindow()
{
    InitializeComponent();

    Map newMap = new Map();
    newMap.setMapStrategy(new SmallMapStrategy());
    newMap.createMap();


    System.Windows.Forms.PictureBox pictureBox1 = new System.Windows.Forms.PictureBox();
    pictureBox1.Paint += new System.Windows.Forms.PaintEventHandler(newMap.grid[3].afficher);

}

这是附属功能：

public override void afficher(object sender, PaintEventArgs e)
{
    e.Graphics.DrawImage(squareImage, pos_x, pos_y, 50, 50);
}

squareImage是对应于Drawing.Image的属性。 pos_x和pos_y是自定义的int32属性。

我想要的是在运行应用程序时查看图像...

由于您使用的PictureBox是Winforms控件，因此您需要将WindowsFormsHost控件添加到Wpf窗体，然后将PictureBox添加到其中。 每当您动态创建控件时，都需要将其添加到Form或Container对象中，否则它将不会显示。

即这样的事情。

MainWindow.xaml

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <WindowsFormsHost Height="175" HorizontalAlignment="Left" Margin="10,10,0,0" Name="windowsFormsHost1" VerticalAlignment="Top" Width="255" />
    </Grid>
</Window>

MainWindow.xaml.cs

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

            System.Windows.Forms.PictureBox picturebox1 = new System.Windows.Forms.PictureBox();
            windowsFormsHost1.Child = picturebox1;
            picturebox1.Paint += new System.Windows.Forms.PaintEventHandler(picturebox1_Paint);
        }

        void picturebox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
        {
            System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(@"C:\Temp\test.jpg");
            System.Drawing.Point ulPoint = new System.Drawing.Point(0, 0);
            e.Graphics.DrawImage(bmp,ulPoint);
        }
    }
}
