Prathamesh Shende 376

I have project in blazor wasm and asp.net core webapi
I implemented the Culture For currency and dateTime format which in en-IN and en-US . SO When I Set en-IN the api does not work because
date format change to dd/MM/yyyy from MM/dd/YYYY

So how to I solve this problem my api call is like GetDataByDate(DateTime date);
parameter is date

How do I solve this issue?

Hi @Prathamesh Shende , could you please share a simple demo which could reproduce your issue?

API
public async Task<ActionResult<IEnumerable<SalesViewModel>>> GetSalesByCustomer(DateTime dateFrom)
{
return await _context.Sales.Where(a=>a.DateFrom == dateFrom).ToList();

}
Blazor WASM

program.cs
#region Set Globalization and Localization
CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-IN");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-IN");
#endregion
//before run.async()
Service.cs
public async ValueTask<List<SalesViewModel>> GetSalesAsync(DateTime dateFrom)
{
return await _httpClient.GetFromJsonAsync<List<SalesViewModel>>($"{_httpClient.BaseAddress}api/Sales?DateFrom={dateFrom}");
}

So when I send the request from the blazor to api the date format is en-IN I change it as per requirement. so date format in DateFrom will dd/MM/YYYY. so it shows error api not wokring. But when I change the en-US then api works fine because the date format is in MM/dd/yyyyy

I think it should accept every date format if webapp open in europe, us or any other region and show data to customer

Hi @Prathamesh Shende , I think you could custom model binder to allow all of the DateTime format, refer to this answer.

you should be passing dates in iso format. the json serializer should handle this. you also need to decide how timezones are handled.
