【问题标题】:I'm adding text to a word document and need to include subscripts我正在向 word 文档添加文本,并且需要包含下标
【发布时间】:2020-03-28 07:19:19
【问题描述】:

我使用 word interop 打开了一个 word 文档,并添加了几段文本。这些长度取决于一系列因素。然后我像这样在下标中添加一行包含 CR 的文本(字母 CR 的下标不包含在 Unicode 下标中):

            Dim word As Word.Application = New Word.Application()
            Dim doc As Word.Document

            'more code inserting paragraphs here


            Dim Paratext as string

            Paratext = "Elastic Critical Buckling Load  N_CR=(π² (E/Yₘ )I)/(L_CR∙L² )"

            para0 = doc.Content.Paragraphs.Add
            para0.Range.Text = Paratext
            para0.Range.InsertParagraphAfter()
            para0.Range.Style = doc.Styles("Normal")

            Dim Rstart As Int16 = Paratext.IndexOf("CR")
            Dim Rend As Int16 = Paratext.IndexOf("=")

            ' this is wrong: I select the range in the document
            ' using the location in the paragraph.

            Dim SRange = doc.Range(Rstart, Rend)

            SRange.Select()

            Dim currentselection As Word.Selection = word.Selection
            currentselection.Font.Subscript = 1

编辑:我选择了错误的文本。我正在识别刚刚添加的段落中字母 CR 的位置,并将其应用于已经添加了多个段落的文档。因此,文档索引 35 和 36 处的两个字符而不是段落成为下标。 如何获取我刚刚添加的段落开头的索引?

【问题讨论】:

  • 它给出了什么错误?
  • 没有错误,只是不会改变文本
  • 我已经意识到我哪里出错了。我已经确定了段落中“CR”的位置,然后将该范围应用于整个文档。如何在段落中选择范围?

【解决方案1】:

已修复:

Dim word As Word.Application = New Word.Application()
        Dim doc As Word.Document

        'more code inserting paragraphs here

        'locate the end of the document so far
        Dim DocEnd As Int16 = doc.Content.End - 1

        Dim Paratext as string

        Paratext = "Elastic Critical Buckling Load  N_CR=(π² (E/Yₘ )I)/(L_CR∙L² )"

        para0 = doc.Content.Paragraphs.Add
        para0.Range.Text = Paratext
        para0.Range.InsertParagraphAfter()
        para0.Range.Style = doc.Styles("Normal")

        Dim Rstart As Int16 = Paratext.IndexOf("CR")
        Dim Rend As Int16 = Paratext.IndexOf("=")


        Dim SRange = doc.Range(Rstart + DocEnd, Rend + DocEnd)

        SRange.Select()

        Dim currentselection As Word.Selection = word.Selection
        currentselection.Font.Subscript = 1
