EditPoint2.GreaterThan 方法 (TextPoint)

返回 EditPoint 对象的 AbsoluteCharOffset 属性值是否大于给定 TextPoint 对象的属性值。

命名空间:  EnvDTE80
程序集:  EnvDTE80(在 EnvDTE80.dll 中)

语法

声明
Function GreaterThan ( _
    Point As TextPoint _
) As Boolean
bool GreaterThan(
    TextPoint Point
)
bool GreaterThan(
    [InAttribute] TextPoint^ Point
)
abstract GreaterThan : 
        Point:TextPoint -> bool 
function GreaterThan(
    Point : TextPoint
) : boolean

参数

返回值

类型:System.Boolean
如果 Point 的 AbsoluteCharOffset 属性值小于调用 EditPoint 对象的 AbsoluteCharOffset 属性值,则为 true;否则为 false。

实现

EditPoint.GreaterThan(TextPoint)

备注

如果 Point 与调用点对象不在同一文档中,GreaterThan 将引发 ArgumentException 异常。 对于 VirtualPoint,如果参数是 VirtualPointGreaterThan 将比较虚拟位置,否则它将比较物理位置。

示例

Sub GreaterThanExample(ByVal dte As DTE)

    ' 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
public void GreaterThanExample(DTE dte)

    dte.ItemOperations.NewFile(@"General\Text File", "", 
        Constants.vsViewKindPrimary);
    TextDocument txtDoc = 
        (TextDocument)dte.ActiveDocument.Object("");

    // Create an edit point at the empty text document's StartPoint 
    // and EndPoint; CompareEditPoints displays "point1 and point2

    EditPoint point1 = txtDoc.StartPoint.CreateEditPoint();
    EditPoint point2 = txtDoc.EndPoint.CreateEditPoint();
    CompareEditPoints(point1, point2);

    // Insert ten lines of text.

    CompareEditPoints(point1, point2);
}

void CompareEditPoints(EditPoint point1, EditPoint point2)
{
    if (point1.LessThan(point2))
        MessageBox.Show("point1 comes before point2.");
    else if (point1.GreaterThan(point2))
        MessageBox.Show("point2 comes before point1.");
    else if (point1.EqualTo(point2))
        MessageBox.Show("point1 and point2 occupy the same location.");
