Hello Dzenan,

Thanks for your inquiry.
You can use the "Paragraph.AppendHTML()" method to add html string to paragraph, and then save the file in RTF format. Below is the sample code for your reference. If there is any question, please feel free to write back.

Code: Select all

    String HTML = "<H1>Spire.Doc for .NET</H1>";

    //Create a new document
    Document document = new Document();

    //Add a section
    Section sec = document.AddSection();

    //Add a paragraph and append html string
    sec.AddParagraph().AppendHTML(HTML);

    //Save to RTF file
    document.SaveToFile("Result.rtf", FileFormat.Rtf);

    //Get the rtf string
    string rtf = File.ReadAllText("Result.rtf");

Rachel

Hello,

Thanks for your prompt response.
Please make sure your computer can access the online image. I tested the following code with the latest Spire.Doc Pack(hot fix) Version:8.7.5 but found the the image displays as expected, attached is my output file. To help us investigate further, please provide us with your HTML string.

Code: Select all

    String HTML = "<img src='https://www.e-iceblue.com/images/Intro/intro_office.png'/>";
    //Create a new document
    Document document = new Document();

    //Add a section
    Section sec = document.AddSection();

    //Add a paragraph and append html string
    sec.AddParagraph().AppendHTML(HTML);

    //Save to RTF file
    document.SaveToFile("Result.rtf", Spire.Doc.FileFormat.Rtf);

Hi,
I have latest 8.7.5.0 version installed via nuget.
Can you test on your environment with this html ?

Thanks

Hello,

Thanks for your sharing.
I tested the code below to append your html string to paragraph but got the "XmlException" error. Have you encountered the same issue? If not, please provide your test environment information for further investigation, such as your OS information (E.g. Windows 7, 64 bit) and region setting (E.g. China, Chinese).

Code: Select all

            String HTML = File.ReadAllText("oneStringHtml.txt");
            Document document = new Document();
            Section sec = document.AddSection();
            sec.AddParagraph().AppendHTML(HTML);
            document.SaveToFile("Result.rtf", Spire.Doc.FileFormat.Rtf);

Anyway, the "XmlException" issue has been posted to our Dev team with the ticket SPIREDOC-4820 for further investigation. If there is any update, we will inform you.
