EditPoint2.LessThan 方法
傳回被呼叫 EditPoint 物件的 AbsoluteCharOffset 值是否小於指定 TextPoint 物件的值。
命名空間： EnvDTE80
組件： EnvDTE80 (在 EnvDTE80.dll 中)

Function LessThan ( _
Point As TextPoint _
) As Boolean
bool LessThan(
TextPoint Point
)
bool LessThan(
[InAttribute] TextPoint^ Point
)
abstract LessThan :
Point:TextPoint -> bool
function LessThan(
Point : TextPoint
) : boolean
參數
Point
類型：TextPoint必要項。 要與呼叫點物件作比較的 TextPoint。
傳回值
類型：Boolean
如果相較之下 Point 的 AbsoluteCharOffset 屬性值大於呼叫點物件的 AbsoluteCharOffset 屬性值，則為 true，否則為 false。
備註
如果 Point 與呼叫點物件不在相同的文件中，LessThan 就會擲回 ArgumentException。 如果引數是 VirtualPoint，LessThan 會與 VirtualPoint 物件比較虛擬位置。 否則在其他情況下，它會比較實體位置。

' Create a new text file.
dte.ItemOperations.NewFile()
Dim txtDoc As TextDocument = _

' Create an edit point at the empty text document's StartPoint
' and EndPoint; CompareEditPoints displays "point1 and point2
' occupy the same location."
Dim point1 As EditPoint = txtDoc.StartPoint.CreateEditPoint()
Dim point2 As EditPoint = txtDoc.EndPoint.CreateEditPoint()
CompareEditPoints(point1, point2)
' Insert ten lines of text.
Dim i As Integer
For i = 1 To 10
