How to create a link inside a cell using EPPlus

Question

I am trying to figure out how to write a Hyperlink inside a cell using EPPlus instead of the cell containing the link text. I need it to be recognized as a link and be clickable

Answer 1

Based on provided answers and documentation I was able to create an extension method that also deals with proper hyperlink formatting. It creates a named style, if needed, and use that style for all subsequent hyperlinks:

public static void WriteHyperlink(this ExcelRange cell, string text, string url, bool excelHyperlink = false, bool underline = true)
{
    if (string.IsNullOrWhiteSpace(text))
        return;

    // trying to reuse hyperlink style if defined
    var workBook = cell.Worksheet.Workbook;
    string actualStyleName = underline ? HyperLinkStyleName : HyperLinkNoUnderlineStyleName;

    var hyperlinkStyle = workBook.Styles.NamedStyles.FirstOrDefault(s => s.Name == actualStyleName);
    if (hyperlinkStyle == null)
    {
        var namedStyle = workBook.Styles.CreateNamedStyle(actualStyleName);  
        namedStyle.Style.Font.UnderLine = underline;
        namedStyle.Style.Font.Color.SetColor(Color.Blue);
    }

    if (excelHyperlink)
        cell.Hyperlink = new ExcelHyperLink(url) { Display = text };
    else
    {
        cell.Hyperlink = new Uri(url);
        cell.Value = text;
        cell.StyleName = actualStyleName;
    }
}

Without the styling, the hyperlink will look just as regular text, if cell.Hyperlink = new Uri(url); is used without explicit styling (although the cursor will properly indicate that the text is actually a hyperlink text).
