با استفاده از Application.StatupPath میتونید مسیر اجرا را بدست بیارید و بعد بجسبانید به فولدر ali و بعد دستور کپی را بنویسید

    // Simple synchronous file copy operations with no user interface.

من فقط یک آدرس میخوام که فایل در اونجا کپی بشه یا move بشه اون آدرس هم در پوشه خود برنامه هست !

در asp آدرس رو با قرار دادن یک ~  میدادیم که مثلا در روت فولدر هست !

باید ادرس مطلق یا فیزیکی باشد پس از Server,MapPath استفاده کنید

تو برنامه ویندوزی از servermapPath مگه میشه استفاده کرد؟

خیر

از Application.StartupPath استفاده کنید
