خطأ فى كود بحث بـ ألف بهمزة وألف بدون همزة والتاء المربوطة

تحية طيبة

بعد بحث وعدة محاولات لعمل كلاس تقوم بدورها بالبحث بالهمزات والتاء المربوطة أو بدون..

وجدت فى منتدى الجافا التالى

اولا اشكرك على مجاملتك الرقيقة

ثانيا انا لم اطلب منك ان تجربها بنص معين مثل "أمجمد أحمد أشرف"

أنا قلت جربها وتركت لك حرية التجربة

طبعا كلامك صحيح عن الاحتمالات ولكن قبل ان تعرضها كنت جربها وجرب غيرها أيضا

الفئة تقوم بالدوران داخل النص واستبدال الحرف أ مثلا بالحرف ا فقط حتى لو كان موجودا ل 20 مرة او اكثر وليس مرة واحدة فقط

على كل قمت باضافة بعض الحروف و اضافة test case واليك الفئة

ولكن فى السطر التالى

		encodedText.Replace(location, (location + arabicChars[0].Length), arabicChars[1]);

ظهر خطأ كالتالى

No overload for method 'Replace' takes 3 arguments

أرجو الإفادة للإهمية
