ICalendar link generator

ICalendar.razor

@using Ical.Net
@using Ical.Net.Serialization
@* requires Ical.Net library from NUGET *@
@if(Calendar != null)
{
    <a href=@dataUrl download=@Filename >@ChildContent</a>
}
@code
{
    [Parameter] public Calendar Calendar { get; set; }

    [Parameter] public RenderFragment ChildContent {get;set;}

    [Parameter] public string Filename { get; set; } = "Calendar.ics";

    string dataUrl => GetDataUrl();

    string GetDataUrl()
    {
        var serializer = new CalendarSerializer();
        var text = serializer.SerializeToString(Calendar);
        var data = System.Text.Encoding.UTF8.GetBytes(text);
        var base64 = Convert.ToBase64String(data);
        return $"data:text/calendar;base64,{base64}";
    }
}

I've updated the gist to use base64 encoding rather than using URL encoding, as it does not corrupt the description or summary, etc.
