Gets or sets the X component of this vector.

The X component of this vector. The default value is 0.
Examples
The following example shows how to check two Vector structures for equality.
// Checks if two Vectors are equal using the overloaded equality operator.
private Boolean vectorEqualityExample()
{
    // Declaring vecto1 and initializing x,y values
    Vector vector1 = new Vector(20, 30);
    // Declaring vector2 without initializing x,y values
    Vector vector2 = new Vector();
    // Boolean to hold the result of the comparison
    Boolean areEqual;
    // assigning values to vector2
    vector2.X = 45;
    vector2.Y = 70;
    // Comparing Vectors for equality
    // areEqual is False
    areEqual = (vector1 == vector2);
    return areEqual;
}
