命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.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 EditPoint 对象的字符偏移量，从 1 开始。

备注

AbsoluteCharOffset 返回文档顶端到对象的字符数。LineCharOffset 属性只确定距离对象所在行的行首的字符数。换行符算作一个字符。

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)
