如何使Windows窗体适合任何屏幕分辨率，以及如何使我的图像大小适合窗体

Question

I have the following code in which I am trying to display an image and play an MP3 song.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Media;
using WMPLib;
using System.Windows;

namespace CreatingInstaller
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.Size = Screen.PrimaryScreen.WorkingArea.Size;
            var size = this.Size;
            var screen = System.Windows.Forms.Screen.PrimaryScreen.Bounds;
            PictureBox pb1 = new PictureBox();
            Image img = Image.FromFile(Application.StartupPath + "\\Input\\CYMERA_20141109_141742.jpg");
            //this.Width = img.Width;
            //this.Height = screen.Height;
            pb1.Image = img;
            //pb1.Width = img.Width;
            //pb1.Height = screen.Height; 
            pb1.Size = this.Size;
            this.Controls.Add(pb1);

            WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();

            wplayer.URL = Application.StartupPath + "\\Input\\Nee Sneham - [www.MazaMp3.com].mp3";
            wplayer.controls.play();
        }
    }
}

When I ran this code Form height is exceeding my screen height and I am unable to see the full image. Image is not fitting in the form.

Can anyone help on this?

Answer 1

对图片框使用锚点 ，也可以对SizeMode使用锚点 。

Answer 2

WindowState = FormWindowState.Maximized;

write the above line on load event of the form.

Answer 3

I think the best in your case is to avoid to use PictureBox, and set the image in the BackgroundImage of the form and set the form BackgroundImageLayout to Stretch.

In this way you can change the size of form and the image will be stretched automatically.
