问题 This question may seem a little trivial at first, but I am experiencing odd OutOfMemory problems since I began implementing this.

Without further ado, here is the code: In my constructor, I am setting up field variables that will hold my Input/Output Stream variables. Along with it, I am creating two other sets of variables for when I am specifically doing IO on custom objects and

问题 I want to store a large string in PDF document somewhere hidden. Right now I have a hidden text field in which I am writing that text. The problem is that when the string size increased upto 10MB I start getting OutOfMemory errors. What will be the best way to store some large hidden string/text to PDF document using iTextSharp ? That text/string should be retrieved later as well. 回答1: Such private data can be stored in PieceInfo dictionaries, also cf. David's answer to the OP's follow-up
