CSV Content Result for ASP.NET Core

CsvContentResult.cs

using Microsoft.AspNetCore.Mvc;

public class CsvContentResult : ContentResult
{
    private const string _contentType = "text/csv";

    public CsvContentResult(string content)
    {
        ContentType = _contentType;
        Content = content;
    }
}

EnumerableExtensions.cs

using System.Text;

namespace System.Collections.Generic
{
    public static class EnumerableExtensions
    {
        public static string ToCsv(this IEnumerable source)
        {
            if (source is null)
            {
                throw new ArgumentNullException(nameof(source));
            }

            var result = new StringBuilder();
            foreach (var item in source)
            {
                foreach (var property in item.GetType().GetProperties())
                {
                    result.Append(property.GetValue(item).ToString()).Append(",");
                }

                result.Append(Environment.NewLine);
            }

            return result.ToString();
        }
    }
}

TestModel.cs

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

public class TestModel : PageModel
{
    // Retreive CSV content from text
    // public IActionResult OnGet() => new CsvContentResult("Hisham,https://www.github.com/hishamco");

    // Retreive CSV content from entity
    public IActionResult OnGet()
    {
        var users = _dbContext.Users.Select(u => new
        {
            Name = u.Name,
            GitHubUrl = u.GitHubUrl
        }).ToCsv();

        return new CsvContentResult(users);
    }
}

@saineshwar this a simple implementation for retrieving CSV directly from within RazorPage / MVC action
