استفاده از چند sream reader و مشکل نخواندن داده

[hsdnhd]

باسلام
من در پروژه خودم میخوام از چند فایل اطلاعات رو بخونم وبریزم توی یک متغیر ممکنه هرکدوم ازاین فایل ها چندهزارکاراکتر داشته باشند بنابراین اطلاعات کمی سنگین هست من از کد زیر برای اینکار استفاده کردم ولی مشکل اینجاست که وقتی یک فایل هست تا حدودی رو کپی میکنه که اون هم کامل نه قسمتی رو دلیلش هم معلوم نیست بقیه اصلا نمی خونن اطلاعات رو تا بریزن توی متغیر مشکل ازکجای کد هست؟

اگه اطلاعات خیلی سنگین هستن نباید کل اطلاعات رو در حافظه لود کنید که این کار باعث ارور overflow و پر بودن رم میشه. هرکاری میخواید بکنید روی دیسک انجام بدید. اگه هم کمکی از دستم برمیاد در مورد کار برنامه بیشتر توضیح بدید تا راهی پیدا کنیم :لبخندساده:
