vb.net - Closing an XML file after reading so it can be deleted -

i have problem deleting xml file after loading .xmldocument.

my code parses xml file specific nodes , allocates values variables.

once complete code processes data based on values xml file.

this works fine until end when try delete xml file still open , error "the process cannot access file because being used process" guess xmldocument reader.

here section of the xml processing code - works fine.

    `dim xmldoc xmldocument = new xmldocument()      xmldoc.load(strfilename)     intpassed = xmldoc.selectsinglenode("//calibrationpassed").innertext     boolcheck = xmldoc.selectsinglenode("//checkscomplete").innertext     intcertrequired = xmldoc.selectsinglenode("//schedule").innertext     console.writeline("calibration passed: " & intpassed)     console.writeline("checks complete:" & boolcheck)     console.writeline("schedule: " & intcertrequired)       strfirstname = xmldoc.selectsinglenode("//firstname").innertext     stremail = xmldoc.selectsinglenode("//email").innertext     strcusemail = xmldoc.selectsinglenode("//customeremail").innertext     strcompanyname = xmldoc.selectsinglenode("//companyname").innertext     strcontractnumber = xmldoc.selectsinglenode("//contractno").innertext      console.writeline("first name: " & strfirstname)     console.writeline("email: " & stremail)     console.writeline("customer email: " & strcusemail)     console.writeline("company name: " & strcompanyname)     console.writeline("contract no: " & strcontractnumber)      console.writeline("xml parsing complete") 

` code being used delete file is:

if system.io.file.exists(strfilename) = true                 system.io.file.delete(strfilename)                 console.writeline("deleted xml file")             end if 

any on i'm going wrong great-fully received.

thanks

xmldocument.load uses stream reader under hood. there 2 strategies avoiding this:

1) using block close/dispose stream automatically , promptly

using xmldoc xmldocument = new xmldocument()     xmldoc.load(strfilename)     'all of copying stuff end using 'now delete file 

2) load xml , avoid using reader:

dim strxml string strxml = system.io.file.readalltext(strfilename) dim xmldoc xmldocument = new xmldocument() xmldoc.loadxml(strxml) 'and rest of code 

the downside 2nd approach example doesn't consider other encoding, should past current problem. dealing various encoding options whole different matter.
