Read large xml file and extract it's data into a form application in C#.Net project -

i want read xml file data , extract information show in form in c#.net vs2008 env. can't read data list in memory, want have .exe file project can run in computer system. think, can't use database saving , retrieving data! please me solve problem!

use system.xml.xmlreader read xml file. forward reader loads bit of xml @ time.

combine iterator method produces ienumerable, such example, myxmldata class representing held in xml file , class forms can work with:

public ienumerable<myxmldata> queryfile(string xmlfile) {     using (var reader = xmlreader.create(xmlfile))     {         // these variables want read each 'object' in         // xml file.         var prop1 = string.empty;         var prop2 = 0;         var prop3 = datetime.today;          while (reader.read())         {             // here you'll have read xml node @ time.             // read, assign appropriate values variables             // declared above.              if (/* have finished reading item? */)             {                 // once you've completed reading xml representing single                 // myxmldata object, return using yield return.                 yield return new myxmldata(prop1, prop2, prop3);             }         }     } } 

the value returned method sequence of myxmldata objects each 1 created on demand file read, 1 @ time. reduce memory requirements large xml file.

you can query myxmldata objects using linq functions. example, can emulate paging using take , skip methods.

// third page - 50 objects per page. queryfile(@"x.xml").skip(100).take(50);
