abstract member EqualTo : EnvDTE.TextPoint -> bool

Public Function EqualTo (Point As TextPoint) As Boolean

Parameters

Point: TextPoint

Required. A TextPoint object to compare to the calling EditPoint point object.

Returns

Boolean

true if Point has the same AbsoluteCharOffset property value as the calling EditPoint point object; otherwise, false.

Remarks

EqualTo throws a ArgumentException exception if Point is not in the same document as the calling point object. With the VirtualPoint, EqualTo compares the virtual positions if the argument is a VirtualPoint. Otherwise, it compares the "physical" positions.
