WPF使用PictureBox

一、添加引用

按照下图添加相关引用

二、代码实现

1.Xaml

<Window x:Class="PictureBoxInWPF.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:PictureBoxInWPF"
        xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <wfi:WindowsFormsHost x:Name="pictureBoxHost" ToolTip="">wfi:WindowsFormsHost>
    Grid>
Window>

2.后台代码

添加了ToolTip，并且鼠标移动ToolTip跟随变化

public partial class MainWindow : Window
{
    System.Windows.Forms.PictureBox m_pictureBox;
    System.Windows.Forms.ToolTip m_toolTip;
    ToolTip m_tp;

    public MainWindow()
    {
        InitializeComponent();

        m_pictureBox = new System.Windows.Forms.PictureBox();
        m_tp = new ToolTip();
        m_toolTip = new System.Windows.Forms.ToolTip();
        m_toolTip.SetToolTip(m_pictureBox, "1");
        m_tp.PlacementTarget = pictureBoxHost;
        pictureBoxHost.Child = m_pictureBox;
        m_pictureBox.Paint += new System.Windows.Forms.PaintEventHandler(picturebox_Paint);
        m_pictureBox.MouseMove += pictureBox_MouseMove;
    }

    //绘制事件
    void picturebox_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
    {
        Bitmap bmp = new Bitmap(@"C:\Users\admin\Pictures\111.jpg");
        System.Drawing.Point ulPoint = new System.Drawing.Point(0, 0);
        e.Graphics.DrawImage(bmp, ulPoint);
        //m_toolTip.Show("222", this);
    }

    private void pictureBox_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
    {
        Random rd = new Random();
        int i = rd.Next(100);
        m_toolTip.SetToolTip(m_pictureBox, i.ToString());
    }
}
