تولید QR_Code در win form
با سلام روش صحیح تولید Qr_Code در ویندوز فرم چه مراحلی داره ؟
برای بارکد از این نمونه استفاده کردم و فکر میکنم برای QR_Code نیاز به DLL استانداردی هست . ممنون میشم دوستان در صورت اطلاع پاسخ دهید

با سلام روش صحیح تولید Qr_Code در ویندوز فرم چه مراحلی داره ؟
برای بارکد از این نمونه استفاده کردم و فکر میکنم برای QR_Code نیاز به DLL استانداردی هست . ممنون میشم دوستان در صورت اطلاع پاسخ دهید
شخصا از ZXing.Net استفاده می کنم که انواع بارکد ها (QR Code, PDF 417, EAN, UPC, Aztec, Data Matrix, Codabar و ...) رو هم ایجاد می کنه و هم میتونه بارکد روی تصاویر رو شناسایی کنه و بخونه.
نحوه اضافه کردن Package به پروژه رو هم که لابد می دونید، دسترسی به اینترنت فراهم باشه، در منوی Project گزینه ...Manage NuGet Packages
(یا در منوی Tools گزینه ...NuGet Package Manager > Manage NuGet Packages for Solution)
کلیک روی بخش Browse، نوشتن اسم Package در کادر Search (مثلا عبارت ZXing.Net) و کلیک روی Package مورد نظر در نتایج جستجو و زدن تیک پروژه و کلیک روی دکمه Install و تمام.
وقتی پروژه رو Build کنید dll های مورد استفاده اون Package کنار فایل اجرایی برنامه تون کپی میشه.

کامل و آموزنده . سپاسگزارم
