json.net - Reading Large JSON file into variable in C#.net -


i trying parse json files , insert sql db.my parser worked fine long files small (less 5 mb).

i getting "out of memory exception" when trying read large(> 5mb) files.

if (system.io.directory.exists(jsonfilepath))                 {                     string[] files = system.io.directory.getfiles(jsonfilepath);                     foreach (string s in files)                     {                         var jsonstring = file.readalltext(s);                         filename = system.io.path.getfilename(s);                         parsejson(jsonstring, filename);                      }                 }

i tried jsonreader approach, no luck on getting entire json string or variable.please advise.

use 64 bit, check rredcat's answer on similar question:

newtonsoft.json - out of memory exception while deserializing big object

newtonsoft jason performance tips

read article david cox tokenizing:

"the basic approach use jsontextreader object, part of json.net library. jsontextreader reads json file 1 token @ time. it, therefore, avoids overhead of reading entire file string. tokens read file, objects created , pushed onto , off of stack. when end of file reached, top of stack contains 1 object — top of big tree of objects corresponding objects in original json file"
