WinDbg and SoS, how do I print/dump a large string?

Question

I am debugging a hangdump coming from a production server using WinDbg with the SoS extension.

There is a string parameter in one of the stacks, that I need to know

Answer 1

I would think twice before dumping 2562638 characters worth of text, but if you really want to, the text is stored following the fields of the string instance, so you can do a du to dump the actual text of the string. The output will look something like this:

00000000`132ab050  "this is an extremely long string"
00000000`132ab090  " of text, so don't even bother t"
00000000`132ab0d0  "o try to dump it to the screen -"

By logging the session output to a file, you can easily capture the output and do whatever post-processing you need.
