C＃Excel.Range使用HTML数据设置单元格值

Question

I need to find a way to set the excel cell value with html and have it display with the correct formatting. We load data from our database that sometimes contains html data with text mark up or html borders. So I need to be able to tell excel that it is html data to render or convert the html to excel mark up or strip the html mark up, but that is not ideal.

var range = (Excel.Range)worksheet.Cells[rowIndex, columnIndex];
range.Value = "<b>This is <i>html text</i></b> that <font>could contain</font> any type of html;<br/>";

I do not have enought reputation to post this as a comment but here it goes: Take a close look at HTML Text with tags to formatted text in an Excel cell There is a solution in VBA that works and it can be translated into c# with a little bit of effort :)

static void Main(string[] args)
    {
        object misValue = System.Reflection.Missing.Value;
        Type excelApplication = Type.GetTypeFromProgID("Excel.Application");
        dynamic excel = Activator.CreateInstance(excelApplication);
        dynamic xlWorkBook = excel.Workbooks.Add(misValue);
        dynamic SourceSheets = xlWorkBook.Worksheets[1];

        Type IeType = Type.GetTypeFromProgID("InternetExplorer.Application");
        dynamic Ie = Activator.CreateInstance(IeType);
        SourceSheets.Range("A1").Value = "<b>This is <i>html text</i></b> that <font>could contain</font> any type of html;<br/>";
        Ie.Visible = false;
        Ie.Navigate("about:blank");
        Ie.document.body.InnerHTML = SourceSheets.Range("A1").Value;
        Ie.document.body.createtextrange.execCommand("Copy");
        SourceSheets.Paste(SourceSheets.Range("A1"));
        Ie.Quit();
        xlWorkBook.SaveAs("test1", misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue);
    }

this is really a basic translation. You have to save/dispose your object properly after but it works for what you are trying to do. I just notice while trying the "allow access" of the internet explorer for the copy/paste bin but i am sure there is a work arround for that.
