Can PDFsharp automatically split a string over multiple pages? - pdfsharp

Question

I want to add the ability to generate a PDF of the content in my application (for simplicity, it will be text-only).
Is there any way to automatically work out how much content will fit in a single page, or to get any content that spills over one page to create a second (third, fourth, etc) page?
I can easily work it out for blocks of text - just split the text by a number of characters into a string array and then print each page in turn - but when the text has a lot of white space and character returns, this doesn't work.
Any advice?
Current code:
public void Generate(string title, string content, string filename)
{
PdfDocument document = new PdfDocument();
PdfPage page;
document.Info.Title = title;
XFont font = new XFont("Verdana", 10, XFontStyle.Regular);
List<String> splitText = new List<string>();
string textCopy = content;
int ptr = 0;
int maxCharacters = 3000;
while (textCopy.Length > 0)
{
//find a space in the text near the max character limit
int textLength = 0;
if (textCopy.Length > maxCharacters)
{
textLength = maxCharacters;
int spacePtr = textCopy.IndexOf(' ', textLength);
string startString = textCopy.Substring(ptr, spacePtr);
splitText.Add(startString);
int length = textCopy.Length - startString.Length;
textCopy = textCopy.Substring(spacePtr, length);
}
else
{
splitText.Add(textCopy);
textCopy = String.Empty;
}
}
foreach (string str in splitText)
{
page = document.AddPage();
// Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);
XTextFormatter tf = new XTextFormatter(gfx);
XRect rect = new XRect(40, 100, 500, 600);
gfx.DrawRectangle(XBrushes.Transparent, rect);
tf.DrawString(str, font, XBrushes.Black, rect, XStringFormats.TopLeft);
}
document.Save(filename);
}

Answer 1

You can download PDFsharp together with MigraDoc. MigraDoc will automatically add pages as needed, you just create a document and add your text as paragraphs.
See MigraDoc samples page:

MigraDoc is the recommended way.
If you want to stick to PDFsharp, you can use the XTextFormatter class (source included with PDFsharp) to create a new class that also supports page breaks (e.g. by returning the count of chars that fit on the current page and have the calling code create a new page and call the formatter again with the remaining text).
