Point inside Polygon check

I have written a method to determine whether a Vector2 lies inside a polygon or outside of it. The polygon is defined by an array of clockwise vertices, p[]. It returns true if the point is inside, false otherwise.

public bool polyCheck(Vector2 v, Vector2[] p)
{
    int j = p.Length-1;
    bool c = false;
    for(int i=0;iv.y^p[j].y>v.y&&v.x<(p[j].x-p[i].x)*(v.y-p[i].y)/(p[j].y-p[i].y)+p[i].x;
    return c;
}

It is perfectly functional, works with all edge cases, and is blazing fast. I want to know how I could make the method look prettier, and have better 'coding practices' though.

-
avoid single letter variable if they aren't iterator variables. If you or Sam the maintainer needs to come back to this method in a few months, neither you nor Sam will grasp at first glance what the variables are about.

-
avoid shortening of method names. polyCheck does not tell anything about what the method tries to do. A name like IsInPolygon would be better. With a more OO approach by adding a Polygon class having a method Contains(Vector2) it would be more clear.

public class Polygon
{
    public Vector2[] Vertices { get; private set; }
    public Polygon(Vector2[] vertices)
    {
        Vertices = vertices;
    }
    public bool ContainsVector(Vector2 vector)
    {
        // do the magic
        return true;
    }
}

-
always use braces {} although they are optional for single lined for's. This will help you to make your code less error prone.

-
let your variables and operators have some space to breathe. This

c^=p[i].y>v.y^p[j].y>v.y&&v.x<(p[j].x-p[i].x)*(v.y-p[i].y)/(p[j].y-p[i].y)+p[i].x;

is just not readable.
