推荐答案

是的，它可能，如果你想改变文件内的东西，你必须使用代码打开它并开始处理它，OpenXML SDK将帮助您实现这一目标。



步骤1：安装nuget包 - DocumentFormat.OpenXml 2.5.0。

步骤2：修改你的代码

Yes, its possible, if you want to change something inside file, you have to open it using code and start working on it, OpenXML SDK will help you to achieve this.

Step1: Install nuget package - DocumentFormat.OpenXml 2.5.0.
Step2: Modify your code

protected void btnUpload_Click(object sender, EventArgs e)
{
    string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);

    FileUpload1.PostedFile.SaveAs(Server.MapPath("~/") + fileName);

    fileName = Server.MapPath("~/") + fileName;
    using (var document = WordprocessingDocument.Open(fileName, true))
    {
        RunProperties runProp = new RunProperties();

        RunFonts runFont = new RunFonts();           // Create font
        runFont.Ascii = "Arial";                     // Specify font family

        DocumentFormat.OpenXml.Wordprocessing.FontSize size = new DocumentFormat.OpenXml.Wordprocessing.FontSize();
        size.Val = new StringValue("48");  // 48 half-point font size
        runProp.Append(runFont);
        runProp.Append(size);

        Run r = document.MainDocumentPart.Document.Descendants<Run>().First();
        r.PrependChild<RunProperties>(runProp);
        document.MainDocumentPart.Document.Save();
    }
