результат:
Memory in use 370 KB, after start
Memory in use 370 KB, after msg create
Memory in use 370 KB, after fs open
Memory in use 12191 KB, after fs copy to msg.stream
Memory in use 12199 KB, after fs.close
Memory in use 32214 KB, after ms2 = msg.GetMStream
Memory in use 32214 KB, after msg.dispose
Memory in use 32239 KB, after msg2 load from ms2
Memory in use 32239 KB, after ms2.close
Memory in use 32239 KB, after msg2.dispose
в чем дело ? как с этим бороться ? (кроме GC.Collect(2, GCCollectionMode.Forced)) |
