Question

我正在用C＃进行内存匹配游戏当用户匹配2张图像时，我希望它们消失或使其不可见我仍然是编码的新手，这是我到目前为止所做的，但是图像不会不可见

    private void apple1_Click(object sender, EventArgs e)
    {
        apple1.Image = Properties.Resources.apple;
        bool condition = true;

        if (apple1.Image==apple2.Image)
        {
            apple1.Visible = false;
            apple2.Visible = false;
        }

    }

    private void apple2_Click(object sender, EventArgs e)
    {
        apple2.Image = Properties.Resources.apple;
    }

Answer 1

设置apple1.Image = Properties.Resources.apple;时，请注意，将Properties.Resources.apple的值（图像）的副本设置为apple1.Image时，分配给apple2.Image时也会发生同样的情况，因此，尽管在视觉上它们似乎具有相同的图像，但是它们指向的是不同的图像（在内存中）。

您可以执行以下一项操作：

1-将图像设置为字典，然后从中加载apple1.Image和apple2.Image：

Dictionary<string, Image> Images = new Dictionary<string, Image>();

Images.Add("apple", Properties.Resources.apple);
Image apple = Properties.Resources.apple;

private void apple1_Click(object sender, EventArgs e)
{
    apple1.Image = Images["apple"];

    if (apple1.Image==apple2.Image)
    {
        apple1.Visible = false;
        apple2.Visible = false;
    }
}

private void apple2_Click(object sender, EventArgs e)
{
    apple2.Image = Images["apple"];
}

2-只需使用另一个属性比较相等性即可：

private void apple1_Click(object sender, EventArgs e)
{
    apple1.Image = Properties.Resources.apple;
    apple1.Tag = "apple";

    if ((string)apple1.Tag==(string)apple2.Tag)
    {
        apple1.Visible = false;
        apple2.Visible = false;
    }
}

private void apple2_Click(object sender, EventArgs e)
{
    apple2.Image = Properties.Resources.apple;
    apple2.Tag = "apple";
}

Answer 2

正如其他人所说，您只需要存储所有资源一次。这是一个可能的示例：

class MyForm
{
    private Dictionary<String, Image> images = new Dictionary<String, Image>();

    public void Init()
    {
         images["apple"] = Properties.Resources.apple;       
    }

    public void Dispose()
    {
        foreach(var item in myDictionary.Values)
        {
           item.Dispose();
        }  
    }

    private void apple1_Click(object sender, EventArgs e)
    {
        apple1.Image = images["apple"];
        bool condition = true;

        if (apple1.Image==apple2.Image)
        {
            apple1.Visible = false;
            apple2.Visible = false;
        }

    }

    private void apple2_Click(object sender, EventArgs e)
    {
        apple2.Image = images["apple"];
    }
}
