how to set the font name for a existing doc,it doesn’t work for the below code

Document doc = new Document("D:\111.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

// This tells Microsoft Word to use Arial for characters 0...127 and
// Times New Roman for characters 128...255.
// Looks like a pretty strange case to me, but it is possible.
builder.getFont().setNameAscii("Arial");
builder.getFont().setNameOther("Times New Roman");
builder.getDocument().save("D:\111.docx");

Hi,

Thanks for your inquiry.

If you would like to change font of the entire document, you should loop through all nodes and change font. You can use DocumentVisitor to achieve this. Here is code example:

Document doc = new Document(@"C:\Temp\input.doc");
FontChanger changer = new FontChanger();
doc.Accept(changer);
doc.Save(@"C:\Temp\out.doc");

///
/// Class inherited from DocumentVisitor, that chnges font.
///
class FontChanger: DocumentVisitor
{
    ///
    /// Called when a FieldEnd node is encountered in the document.
    ///
    public override VisitorAction VisitFieldEnd(FieldEnd fieldEnd)
    {
        // Simply change font name
        ResetFont(fieldEnd.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a FieldSeparator node is encountered in the document.
    ///
    public override VisitorAction VisitFieldSeparator(FieldSeparator fieldSeparator)
    {
        ResetFont(fieldSeparator.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a FieldStart node is encountered in the document.
    ///
    public override VisitorAction VisitFieldStart(FieldStart fieldStart)
    {
        ResetFont(fieldStart.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a Footnote end is encountered in the document.
    ///
    public override VisitorAction VisitFootnoteEnd(Footnote footnote)
    {
        ResetFont(footnote.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a FormField node is encountered in the document.
    ///
    public override VisitorAction VisitFormField(FormField formField)
    {
        ResetFont(formField.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a Paragraph end is encountered in the document.
    ///
    public override VisitorAction VisitParagraphEnd(Paragraph paragraph)
    {
        ResetFont(paragraph.ParagraphBreakFont);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a Run node is encountered in the document.
    ///
    public override VisitorAction VisitRun(Run run)
    {
        ResetFont(run.Font);
        return VisitorAction.Continue;
    }
    ///
    /// Called when a SpecialChar is encountered in the document.
    ///
    public override VisitorAction VisitSpecialChar(SpecialChar specialChar)
    {
        ResetFont(specialChar.Font);
        return VisitorAction.Continue;
    }
    private void ResetFont(Aspose.Words.Font font)
    {
        // if (font.Name == "Arial")
        font.Name = mNewFont;
    }
    // Font by default
    private string mNewFont = "Arial";
}

I hope, this helps.

Best regards,
