How can I solve multi collisions?

Question

Hi,
I have collision between a ball (obj) and  3 bars (obj11, obj22 and obj33).
Every time when I had a collision I suppose to score only one time.
 This is the reason for using missed15, missed25, missed35 and not
    if (!obj11.IsEmpty | !obj22.IsEmpty | !obj33.IsEmpty)
            score++;
            txtScore.Text = score.ToString();
In this case instead of 1 I have hundreds because if multi collision.
Sa my problem is how I get 4 score and so one by one. 1,2 and 3 are OK.
See code for more.

obj11.Intersect(obj);
void gameTimer2_Tick(object sender, object e)
            obj = new Rect();
            obj.X = Canvas.GetLeft(Ball);
            obj.Y = Canvas.GetTop(Ball);
        //    obj.Height = 60; // 50;
        //  obj.Width = 60;  // 50;
            obj.Height =  50;
   obj11 = new Rect();
            obj11.X = Canvas.GetLeft(rect11);
            obj11.Y = Canvas.GetTop(rect11);
            obj11.Height = (double)PipeDifferentY; //Pipe1[1];
            obj11.Width = 1; // 15; //66;
            obj11.Intersect(obj);
if (!obj11.IsEmpty)
    missed15 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();
obj33 = new Rect();
            obj33.X = Canvas.GetLeft(rect33);
            obj33.Y = Canvas.GetTop(rect33);
            obj33.Height = (double)PipeDifferentY; //Pipe1[1];
            obj33.Width = 1; // 15; //66;
            obj33.Intersect(obj);
if (!obj33.IsEmpty)
    missed15 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();
obj22 = new Rect();
            obj22.X = Canvas.GetLeft(rect22);
            obj22.Y = Canvas.GetTop(rect22);
            obj22.Height = (double)PipeDifferentY; //Pipe1[1];
            obj22.Width = 1; // 15; //66;
            obj22.Intersect(obj);
if (!obj22.IsEmpty)
    missed15 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();

Answer 1

Hi.
Thanks for answer.
It works for passing gate 1, 2, 3 I have the sore 3, but at 4 and next gates I have also 3 and not 4 and so.
Please see the project it suppose to work.
void gameTimer2_Tick(object sender, object e)
            obj = new Rect();
            obj.X = Canvas.GetLeft(Ball);
            obj.Y = Canvas.GetTop(Ball);
        //    obj.Height = 60; // 50;
        //  obj.Width = 60;  // 50;
            obj.Height =  50;
   obj11 = new Rect();
            obj11.X = Canvas.GetLeft(rect11);
            obj11.Y = Canvas.GetTop(rect11);
            obj11.Height = (double)PipeDifferentY; //Pipe1[1];
            obj11.Width = 1; // 15; //66;
            obj11.Intersect(obj);
if (!obj11.IsEmpty)
    missed15 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();
obj22 = new Rect();
            obj22.X = Canvas.GetLeft(rect22);
            obj22.Y = Canvas.GetTop(rect22);
            obj22.Height = (double)PipeDifferentY; //Pipe1[1];
            obj22.Width = 1; // 15; //66;
            obj22.Intersect(obj);
if (!obj22.IsEmpty)
    missed25 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();
obj33 = new Rect();
            obj33.X = Canvas.GetLeft(rect33);
            obj33.Y = Canvas.GetTop(rect33);
            obj33.Height = (double)PipeDifferentY; //Pipe1[1];
            obj33.Width = 1; // 15; //66;
            obj33.Intersect(obj);
if (!obj33.IsEmpty)
    missed35 = 1;
    missedTotal = missed15 + missed25 + missed35;
    txtScore.Text = missedTotal.ToString();
