HtmlToPdf converter = new HtmlToPdf();

// Convert the HTML code to a PDF file
converter.ConvertHtmlToFile("Hello World from HiQPdf !", null, "html_to_file.pdf");

// Convert the HTML page from URL to a PDF file
string urlToConvert = "http://www.hiqpdf.com";
converter.ConvertUrlToFile(urlToConvert, "url_to_file.pdf");
```

To convert a HTML string or an URL to a PDF document in a memory buffer and then save it to a file you can use the C# code below.

```csharp
// Create the HTML to PDF converter object

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("Hello World from HiQPdf !", null);

// Save the PDF data to a file
System.IO.File.WriteAllBytes("html_to_memory.pdf", htmlToPdfData);

// Convert the HTML page from URL to memory
string urlToConvert = "http://www.hiqpdf.com";
byte[] urlToPdfData = converter.ConvertUrlToMemory(urlToConvert);

// Save the PDF data to a file
