为什么本地PC和服务器上的日期格式不同

Question

We are developing .NET Core 2.2 application. We noticed that date format is different on localhost than on the remote server.

• Localhost: 18. 06. 2020 15:12:53
• Remote IIS server: 18.6.2020 15:12:53

Date is displayed in *.cshtml using @Html.DisplayFor(model => model.CreatedAt) . Why is date format different although localhost and server use the same Startup.cs file? We want to have the format that the remote server produces on localhost as well.

Startup.cs :

public void ConfigureServices(IServiceCollection services)
{
    ...    
    services.Configure<RequestLocalizationOptions>(options =>
    {
        options.DefaultRequestCulture = new Microsoft.AspNetCore.Localization.RequestCulture("sl-SI");
        options.SupportedCultures = new List<CultureInfo> { new CultureInfo("sl-SI") };
    });
    ...
}

public void Configure(IApplicationBuilder app)
{
    ...
    app.UseRequestLocalization();
    ...
}

I encountered similar issue and below code solved my issue.

Apply Culture inside Configure like below.

public void Configure(IApplicationBuilder app)
{
    var cultureInfo = new System.Globalization.CultureInfo("sl-SI");
    System.Globalization.CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
    System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;

    // your code
}

Edit I would recommend using culture value from the appsettings.json . This way in future you need to update culture you don't need new build. Just update appsettings.json and restart the server will work.

public void Configure(IApplicationBuilder app)
{
    // Get Culture Info from appsettings and set Default culture for application.
    // If not found culture value from appsettings then use "sl-SI"
    var culture = Configuration.GetValue<string>("AppSettings:Culture") ?? "sl-SI";
    var cultureInfo = new System.Globalization.CultureInfo(culture);
    System.Globalization.CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
    System.Globalization.CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;

    // your code
}
