Question

我使用EPPlus生成Excel文件。

我的意思是我需要将HTML文本（粗体，斜体，字体颜色，名称，大小参数）转换为Excel Cell。我想它需要创建多样式的单元格，如：

单元格文本是“你好！”
我想要的风格是：

he - bold  
ll - italic  
o! - red colored font

或（更复杂）

hello! - bold  
ll - italic (also bold)  
o! - red colored (also bold)

我了解MS OpenXML库（它允许我做我需要的）。这是一个很好但有点复杂的实现库。

解决！我可以用它：

FileInfo fi = new FileInfo(@"c:\Book1.xlsx");

      using (ExcelPackage package = new ExcelPackage(fi))
      {
        // add a new worksheet to the empty workbook
        ExcelWorksheet worksheet = package.Workbook.Worksheets["Inv"];
        //Add the headers

        worksheet.Cells[2, 1].IsRichText = true;
        ExcelRichText ert = worksheet.Cells[2, 1].RichText.Add("bugaga");
        ert.Bold = true;
        ert.Color = System.Drawing.Color.Red;
        ert.Italic = true;

        ert = worksheet.Cells[2, 1].RichText.Add("alohaaaaa");
        ert.Bold = true;
        ert.Color = System.Drawing.Color.Purple;
        ert.Italic = true;

        ert = worksheet.Cells[2, 1].RichText.Add("mm");
        ert.Color = System.Drawing.Color.Peru;
        ert.Italic = false;
        ert.Bold = false;


        package.Save();
      }

Answer 2

出于某种原因，安东的回答对我没有用。我不得不使用：

FileInfo fi = new FileInfo(@"c:\Book1.xlsx");

using (ExcelPackage package = new ExcelPackage(fi))
{
    // add a new worksheet to the empty workbook
    ExcelWorksheet worksheet = package.Workbook.Worksheets["Inv"];

    //add multi-coloured text to a cell
    worksheet.Cells[2, 1].IsRichText = true;
    ExcelRichTextCollection rtfCollection = worksheet.Cells[2, 1].RichText;
    ExcelRichText ert = rtfCollection.Add("bugaga");
    ert.Bold = true;
    ert.Color = System.Drawing.Color.Red;
    ert.Italic = true;

    ert = rtfCollection.Add("alohaaaaa");
    ert.Bold = true;
    ert.Color = System.Drawing.Color.Purple;
    ert.Italic = true;

    ert = rtfCollection.Add("mm");
    ert.Color = System.Drawing.Color.Peru;
    ert.Italic = false;
    ert.Bold = false;

    package.Save();
}

我为此创建了一个扩展方法，这有助于减少代码：

public static class RichtTextExtensions
{
    public static ExcelRichText Add(this ExcelRichTextCollection richTextCollection,
        string text, bool bold = false, bool italic = false, Color? color = null, float size = 11,
        bool underline = false, string fontName = "Segoe UI Light")
    {
        var richText = richTextCollection.Add(text);

        richText.Color = color ?? Color.Black;
        richText.Bold = bold;
        richText.Italic = italic;
        richText.Size = size;
        richText.FontName = fontName;
        richText.UnderLine = underline;

        return richText;
    }
}

并使用它： var worksheet = package.Workbook.Worksheets.Add（＆＃34; Sheet1＆＃34;）;

using (ExcelRange cellRange = worksheet.Cells[1,1])
{
    cellRange.RichText.Add("This is ", size: 18, underline:true);
    cellRange.RichText.Add("a simple ", bold: true, size: 18, underline: true);
    cellRange.RichText.Add("test ", size: 18, underline: true);
    cellRange.RichText.Add("of the extension method", bold: true, size: 18, underline: true);
}

不确定为什么EPPlus还没有这样的东西，或者他们这样做，我错过了它。
