با سلام :
من افزونه ای که مدیر محترم کرامتی اعلام فرمودند را نصب کردم.
ولی یه ریزه گیج شدم.
زمانی که این افزونه نصب است چه اتفاقی در دات نت فریم ورک 4 (VS 2010) می افتد ؟
بدون نصب افزونه از چه کدهایی باید در PAGE_LOAD استفاده نماییم و با افزونه چطور؟
در لینک مورد نظر یه CONSOLE APP داشتیم که با دات نت فریم ورک 2 و 3.5 به خوبی در VS 2010 کار می کنه ، اما وفتی .NET FRAMEWORK رو به 4 تغییر می دیم در یک سری از خطوط ارور می دهد.(ارورها درکلاس PersianCultureHelper)
کد مورد نظر در پروژه پس از اعمال تغییرات در نام گذاری ها به صورت زیر شد :
using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.Globalization;

واما خطوط دارای ارور :
//cultureTableRecordUseCurrentCalendar = cultureTableRecord.GetMethod("UseCurrentCalendar", BindingFlags.NonPublic | BindingFlags.Instance);
---------------------------------------
//object obj2 = dateTimeFormatInfoCultureTableRecord.GetValue(info );
//cultureTableRecordUseCurrentCalendar.Invoke(obj2, new object[] { calendarID.GetValue(calendar, null) });
چگونه این ارورها را رفع نمایم؟
فکر می کنم این کدها در ارتباط با اسمبلی دات نت هستند که برای تحقیق درمورد آنها باید Reflector را در دات نت بررسی کرد.
واما کدی که در page_Load استفاده می کنم به صورت زیر است :
CultureInfo facultureinfo = new CultureInfo("fa-IR");
PersianCultureHelper.SetPersianOptions(faculturein fo);
Thread.CurrentThread.CurrentCulture = facultureinfo;
واین در حالتی ست که افزونه نصب است.
اگر راهنمایی بفرمایید ممنون می شوم
باتشکر
