How to "cast" an Object

Question

I have a function that receives an array of Objects.

I also have a class called Rectangle but when I iterate the array of objects I need the Object in that index to be casted as Rectangle and not as object because the function I will use needs the parameter to be type Rectangle:

    //For collision handling - Receives one rectangle
    public bool IsColliding(Rectangle collisionRectangle)
    {
        return this.destinationRect.Intersects(collisionRectangle);
    }

    //Overloading - Receives an array with multiple Rectangles
    public bool IsColliding(Object[] collisionRectangles)
    {
        for(int i = 0; i <= collisionRectangles.Length; i++)
        {
            //CODE WILL FAIL HERE - The method "Intersects" requires and object of type Rectangle
            if(this.destinationRect.Intersects((Rectangle)collisionRectangles[i]))
            {
                return true;
            }
        }
        return false;
    }

EDIT 1:

Declaration of the array before passing it to the function:

Object[] buildingCollitionRectangles =
        {
            new Rectangle[144, 16, 96, 32],
            new Rectangle[144, 48, 96, 64]
        };

Trying to use the method like this:

if(!player.IsColliding(buildingCollitionRectangles))
{
    updatePlayerInput();
}

EDIT 2:

Trying to store Rectangles in a Rectangle[] array:

Answer 1

All right, I think we found it - you used square brackets instead of parentheses for the Rectangle constructor. As is, I think you're actually allocating two enormous multi-dimensional arrays of Rectangle objects. https://msdn.microsoft.com/en-us/library/microsoft.xna.framework.rectangle.rectangle.aspx definitely shows you need parentheses.

Try this:

Rectangle[] buildingCollitionRectangles =
        {
            new Rectangle(144, 16, 96, 32),
            new Rectangle(144, 48, 96, 64)
        };

(Note that I think this should also solve the problem of not being able to use a Rectangle[] array)
