public CoordinateCompare()

Methods

Compare(object, object)

Compares two object and returns a value indicating whether one is less than, equal to or greater than the other.

public int Compare(object x, object y)

Parameters

x object

First Coordinate object to compare.

y object

Second Coordinate object to compare.

Returns

int

<table cellspacing="0" class="dtTABLE"> <TR VALIGN="top"> <TH width=50%>Value</TH> <TH width=50%>Condition</TH> </TR> <TR VALIGN="top"> <TD width=50%>Less than zero</TD> <TD width=50%><I>a</I> is less than <I>b</I>.</TD> </TR> <TR VALIGN="top"> <TD width=50%>Zero</TD> <TD width=50%><I>a</I> equals <I>b</I>.</TD> </TR> <TR VALIGN="top"> <TD width=50%>Greater than zero</TD> <TD width=50%><I>a</I> is greater than <I>b</I>.</TD> </TR> </table>

Remarks

If a implements IComparable, then a. CompareTo (b) is returned; otherwise, if b implements IComparable, then b. CompareTo (a) is returned. Comparing a null reference (Nothing in Visual Basic) with any type is allowed and does not generate an exception when using IComparable. When sorting, a null reference (Nothing) is considered to be less than any other object.
