Below is the code snippet:

public Task ConvertHtmlAsync(string html, DocumentLayout layout)
{
// Set license
License license = new License();
license.SetLicense(“Aspose.Total.lic”);

        // Set margins. This value is in points but other units like
        // Inches and centimeters can also be used as 12inch or 12cm
        var margin = new MarginInfo
        {
            Top = layout.Margin.Top,
            Bottom = layout.Margin.Bottom,
            Left = layout.Margin.Left,
            Right = layout.Margin.Right
        };

        // Instantiate an object PDF class
        var pdf = new Document();
        var fragment = new HtmlFragment(html);

        var page = pdf.Pages.Add();
        page.PageInfo.Margin = margin;
        page.PageInfo.IsLandscape = layout.Orientation == DocumentOrientation.Landscape;
        page.Paragraphs.Add(fragment);

        MemoryStream stream = new MemoryStream();
        pdf.Save(stream);

        return Task.FromResult(stream);
    }

We are getting the same error when using he latest version of Aspose.PDf (ver 20.1 ). Below is sample code with all of the variables defined.

Code Snippet:

var html = "<html><body><table><colgroup><col /><col /></colgroup><thead><tr><th><strong></strong></th><th><strong></strong></th></tr></thead><tbody><tr><td>&nbsp;</td><td>&nbsp;</td></tr></tbody></table></body></html>";

License license = new License();
license.SetLicense(“Aspose.Total.lic”);

var margin = new MarginInfo
{
Top = 24,
Bottom = 24,
Left = 24,
Right = 24
};

var pdf = new Document();
var fragment = new HtmlFragment(html);

var page = pdf.Pages.Add();
page.PageInfo.Margin = margin;
page.PageInfo.IsLandscape = true;
page.Paragraphs.Add(fragment);

MemoryStream stream = new MemoryStream();
pdf.Save(stream);(post withdrawn by author, will be automatically deleted in 24 hours unless flagged)
