Java ByteArrayInputStream in C# using iTextSharp XMLWorker

Question

I am using ITextSharp and I wanted to include CSS to my PDF. Below is my current code:

ByteArrayInputStream bis = new ByteArrayInputStream(htmlSource.toString().getBytes());  
ByteArrayInputStream cis = new ByteArrayInputStream(cssSource.toString().getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, bis, cis);

But the problem is that I lack a reference for ByteArrayInputStream. Even System.IO cannot fix the error. Are there any other workarounds to this?

Thank you very much!

That code looks like Java version of iText. Are you sure u need help with C#? If so, can you post your C# code? — Mike Hixson, Mar 02 '17 at 04:51
If you try to port java samples to .Net, `ByteArrayInputStream` and `ByteArrayOutputStream` usually become `MemoryStream`. — mkl, Mar 02 '17 at 05:17
@MikeHixson I need help on converting it to **C#** but I'm new to IText. My current code uses `parseXHtml` but does not have the CSS parameter but I realized that I **need** to include CSS in my PDF. The code above is the only snippet that I saw online that incorporates CSS and HTML using `parseXHtml`. — JPaulPunzalan, Mar 02 '17 at 07:32
@mkl Hi, could you help me on converting the `ByteArrayInputStream` code above into C# including the **Memory Stream**? — JPaulPunzalan, Mar 02 '17 at 07:33

A simple, working example to get you started:

var html = "<h1>H1</h1>";
var css = "h1 {font-size: 2em;}";

using (var htmlStream = new MemoryStream(Encoding.UTF8.GetBytes(html)))
{
    using (var cssStream = new MemoryStream(Encoding.UTF8.GetBytes(css)))
    {
        using (var memoryStream = new MemoryStream())
        {
            using (var document = new Document())
            {
                PdfWriter writer = PdfWriter.GetInstance(
                    document, memoryStream
                );
                document.Open();
                XMLWorkerHelper.GetInstance().ParseXHtml(
                    writer, document, htmlStream, cssStream
                );
            }
            File.WriteAllBytes(OUTPUT_FILE, memoryStream.ToArray());
        }
    }
}
