Question

嗨我有一个小问题我创建了一个计时器来显示6张图片它循环通过图片盒1和2中的图片但是由于某种原因它不显示任何图片只是一个x标记。
我的图片格式正确，但我不确定问题是什么，任何人都可以帮忙吗？

    string[] picture = {
                       @"ImageResource\Die_Images\die1.jpg",
                       @"ImageResource\Die_Images\die2.jpg",
                         @"ImageResource\Die_Images\die3.jpg",
                           @"ImageResource\Die_Images\die4.jpg",
                             @"ImageResource\Die_Images\die5.jpg",
                                @"ImageResource\Die_Images\die6.jpg"};
    int index = 0;
    public Form1()
    {
        InitializeComponent();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        pictureBox2.ImageLocation = string.Format(@"ImageResource\Die_Images\{0}.jpg", index);
        pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
        index++;
        if (index >= picture.Length)
            index = 0;
        else
            pictureBox1.ImageLocation = string.Format(@"ImageResource\Die_Images\{0}.jpg", index);
            pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;

    }

    private void button1_Click(object sender, EventArgs e)
    {
        timer1.Start();
    }

    private void button2_Click(object sender, EventArgs e)
    {
        timer1.Stop();
    }

Answer 1

这应该

pictureBox2.ImageLocation = string.Format(@"ImageResource\Die_Images\{0}.jpg", index);

是吗？

pictureBox2.ImageLocation = string.Format(@"ImageResource\Die_Images\die{0}.jpg", index);

Answer 2

您需要"die"+index

 string.Format(@"ImageResource\Die_Images\{0}.jpg", "die"+index);
                                                      ^^^

您的图片名称为die1.jpg，die2.jpg ...但您尝试显示1.jpg，2.jpg等等...此外，您应该开始索引来自1而不是0。
