EditPoint.EqualTo 方法 (TextPoint)

發行項
08/12/2011

傳回數值，指出指定點物件與呼叫之 EditPoint 物件的 AbsoluteCharOffset 值是否相等。

命名空間： EnvDTE
組件： EnvDTE (在 EnvDTE.dll 中)

語法

'宣告
Function EqualTo ( _
    Point As TextPoint _
) As Boolean

bool EqualTo(
    TextPoint Point
)

bool EqualTo(
    [InAttribute] TextPoint^ Point
)

abstract EqualTo : 
        Point:TextPoint -> bool

function EqualTo(
    Point : TextPoint
) : boolean

參數

Point
型別：EnvDTE.TextPoint
必要項。要與呼叫 EditPoint 點物件作比較的 TextPoint 物件。

傳回值

型別：System.Boolean
如果 Point 有與呼叫 EditPoint 點物件相同的 AbsoluteCharOffset 屬性值，則為 true，否則為 false。

實作

TextPoint.EqualTo(TextPoint)

備註

如果 Point 與呼叫點物件所在的文件不同，EqualTo 就會擲回 ArgumentException 例外狀況。如果引數是 VirtualPoint，則 EqualTo 與 VirtualPoint 會針對虛擬位置進行比較，否則兩者會針對「實體」位置進行比較。

範例

Sub EqualToExample(ByVal dte As DTE2)

    ' Create a new text file.
    dte.ItemOperations.NewFile()
    Dim txtDoc As TextDocument = _
        CType(dte.ActiveDocument.Object(), 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
        point1.Insert("Line " & i.ToString() & vbCrLf)
    Next

    ' Create an edit point at the text document's StartPoint and 
    ' EndPoint; CompareEditPoints displays "point1 comes before
    ' point2."
    point1 = txtDoc.StartPoint.CreateEditPoint()
    point2 = txtDoc.EndPoint.CreateEditPoint()
    CompareEditPoints(point1, point2)

End Sub

Sub CompareEditPoints(ByVal point1 As EditPoint, _
    ByVal point2 As EditPoint)

    If point1.LessThan(point2) Then
        MsgBox("point1 comes before point2.")
    ElseIf point1.GreaterThan(point2) Then
        MsgBox("point2 comes before point1.")
    ElseIf (point1.EqualTo(point2)) Then
        MsgBox("point1 and point2 occupy the same location.")
    End If

End Sub
