10/25/2012

获取文档开头到 EditPoint2 对象的字符偏移量，从 1 开始。

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

语法

声明
ReadOnly Property AbsoluteCharOffset As Integer

int AbsoluteCharOffset { get; }

property int AbsoluteCharOffset {
    int get ();
}

abstract AbsoluteCharOffset : int

function get AbsoluteCharOffset () : int

属性值

类型：System.Int32
从文档开头到 EditPoint2 对象的字符偏移量，从 1 开始。

备注

AbsoluteCharOffset 返回从文档开头到该对象的字符数，而 LineCharOffset 属性仅确定从该对象所在行开头到该对象的字符数。

警告
在此属性中，所有新行字符或序列作为单个字符计数。例如，Visual Basic 中通过 vbCrLf（回车符 + 换行符）表示的换行符计为一个单独的字符。

字符编号从 1 开始。

示例

Sub AbsoluteCharOffsetExample(ByVal dte As DTE2)

    ' Create a new text file.
    dte.ItemOperations.NewFile()

    ' Create an EditPoint at the start of the new document.
    Dim doc As TextDocument = _
        CType(dte.ActiveDocument.Object("TextDocument"), TextDocument)
    Dim point As EditPoint = doc.StartPoint.CreateEditPoint

    Dim i As Integer

    ' Insert 10 lines of text.
    For i = 1 To 10
        point.Insert("This is a test." & vbCrLf)
    Next

    ' Display EditPoint properties.
    MsgBox( _
        "AbsoluteCharOffset: " & point.AbsoluteCharOffset & vbCrLf & _
        "AtEndOfDocument: " & point.AtEndOfDocument & vbCrLf & _
        "AtEndOfLine: " & point.AtEndOfLine & vbCrLf & _
        "AtStartOfDocument: " & point.AtStartOfDocument & vbCrLf & _
        "AtStartOfLine: " & point.AtStartOfLine)

End Sub
