Unknown File Format exception

Need to understand what I am doing wrong:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The following code is throwing an exception “Unknown file format.”, on theline:

Document doc = new Document(memoryStream);

Snippet of code:

ASPxHtmlEditor oEditor = (DevExpress.Web.ASPxHtmlEditor.ASPxHtmlEditor)oControl;

if (oEditor.Html.Length > 0)


#region Convert HTML to RTF with Aspose.Words

byte[] HTML = System.Text.Encoding.GetEncoding("iso-8859-1").GetBytes(oEditor.Html);

System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(HTML);

Document doc = new Document(memoryStream);

RtfSaveOptions options = new RtfSaveOptions();

MemoryStream dstStream = new MemoryStream();

doc.Save(dstStream, options);

dstStream.Position = 0;

StreamReader reader = new StreamReader(dstStream);

sText = reader.ReadToEnd();

Utils.Log(String.Format("RTF: {0}", sText), Utils.LogCategory.DEBUG);




Thanks for your request. I think, in your case, you can explicitly specify load format:


LoadOptions options = new LoadOptions(Aspose.Words.LoadFormat.Html, "", "");

Document doc = new Document(stream, options);

Hope this helps.

Best regards,
