Set cultureinfo in asp net core to have a as currencydecimalseparator instead

ASP.NET is a widely used programming language for developing web applications. One common requirement in ASP.NET Core is to set the CultureInfo to have a specific currency decimal separator. In this article, we will explore how to achieve this with examples.

To begin with, let's take a look at the ASP.NET code snippet that sets the CultureInfo in ASP.NET Core:


using System.Globalization;

public  
{
    public void ConfigureServices(IServiceCollection )
    {
        services.Configure(options =>
        {
            options.DefaultRequestCulture = new RequestCulture("en-US");
            options.SupportedCultures = new List { new CultureInfo("en-US") };
            options.SupportedUICultures = new List { new CultureInfo("en-US") };
        });
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        //  configuration code

        app.UseRequestLocalization();
        
        // Other configuration code
    }
}

In the above code, we are configuring the RequestLocalizationOptions to set the default culture to “en-US”. This will ensure that the currency decimal separator is set to a period (.) instead of a comma (,).

Now, let's say we want to set the currency decimal separator to a comma (,) instead. We can achieve this by the ConfigureServices method as follows:


public void ConfigureServices(IServiceCollection services)
{
    services.Configure(options =>
    {
        options.DefaultRequestCulture = new RequestCulture("en-US");
        options.SupportedCultures = new List { new CultureInfo("en-US") };
        options.SupportedUICultures = new List { new CultureInfo("en-US") };

        var enUS = new CultureInfo("en-US");
        enUS.NumberFormat. = ",";
        options.DefaultRequestCulture = new RequestCulture(enUS);
    });
}

In the above code, we create a new CultureInfo object for “en-US” and modify its NumberFormat.CurrencyDecimalSeparator to “,”. We then set this modified CultureInfo as the default request culture.

By this change, the currency decimal separator will be set to a comma (,) instead of a period (.) in ASP.NET Core.

Conclusion

In this article, we discussed how to set the CultureInfo in ASP.NET Core to have a specific currency decimal separator. We provided an of how to modify the ConfigureServices method to achieve this. By these steps, you can customize the currency decimal separator according to your requirements in ASP.NET Core.
