c# - 单击按钮时图像移动

Question

我想通过单击按钮将一个图片框中的图像移动到另一个图片框中，反之亦然，我很确定我的代码在理论上应该可以工作，但由于某种原因它不会执行。任何帮助将不胜感激!!这是我的代码:

    int chicken_move = 0;

    private void button_Chicken_Click(object sender, EventArgs e)
    {
        chicken_move++;
        if (chicken_move > 1)
        {
            chicken_move = 0;
        }

        switch (chicken_move)
        {
            case 0:

                pictureBox_Micro.Image = pictureBox_Uncooked.Image;
                pictureBox_Uncooked.Image = null;

                break;

            case 1:

                pictureBox_Uncooked.Image = pictureBox_Micro.Image;
                pictureBox_Micro.Image = null;

                break;
        }

您需要使用交换技术来更改图片。否则，您将在第一次点击后丢失它。

 public partial class Form1 : Form
    {
        private bool isFirstOne;
        Image forSwap;
        public Form1()
        {
            InitializeComponent();

        string path1 = @"C:\Users\...\...\somePic.png";

        pictureBox1.Image = Image.FromFile(path1);

        forSwap = null;
        isFirstOne = false;
    }


    private void button1_Click(object sender, EventArgs e)
    {
        switch (isFirstOne)
        {
            case true:
                forSwap = pictureBox2.Image;
                pictureBox1.Image = pictureBox2.Image;
                pictureBox2.Image = null;
                break;

            case false:
                forSwap = pictureBox1.Image;
                pictureBox2.Image = pictureBox1.Image;
                pictureBox1.Image = null;
                break;
        }
        isFirstOne = !isFirstOne;
    }
}
