var标签= this.Controls.OfType <Label>（）;</label> <Label>控制除1以外的所有标签</label>

Question

I have a maze game that uses labels as walls and .IntersectsWith to handle colision. My problem is that since my "player" is also a label it messes things up with my code. What i want is for the player to be able to move meanwhile it also cant colide with all the other labels.

What the problem really is is that this part makes the player unable to move for some reason. Never mind the if () with break it was just an experiment.

 var labels = this.Controls.OfType<Label>();

        foreach (var label in labels)
        {
            if (label.Bounds.IntersectsWith(player.Bounds))
            {
                break;
            }
            if (player.Bounds.IntersectsWith(label.Bounds))
            {

 namespace mazeGame
{
public partial class Form1 : Form
{
    bool down;
    bool left;
    bool right;
    bool up;

    public Form1()
    {
        InitializeComponent();
    }

    private void panel1_Paint(object sender, PaintEventArgs e)
    {

    }

    private void Form1_KeyUp(object sender, KeyEventArgs e)
    {

    }

    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Right)
        {
            right = true;
            left = false;
            up = false;
            down = false;
        }
        if (e.KeyCode == Keys.Left)
        {
            left = true;
            right = false;
            up = false;
            down = false;
        }
        if (e.KeyCode == Keys.Up)
        {
            up = true;
            left = false;
            right = false;

    private void timer1_Tick(object sender, EventArgs e)

        var labels = this.Controls.OfType<Label>();

        foreach (var label in labels)

            if (label.Bounds.IntersectsWith(player.Bounds))
            {
                break;
            }
            if (player.Bounds.IntersectsWith(label.Bounds))
            {

                if (right == true)

            if (right == true)

您可以通过以下方式将player标签从选择中排除：

var labels = this.Controls.OfType<Label>().Where(l => l.Name != "Player")
