Imagine I have a program running on a server and I want to have it do a certain operation at 9am, what's the best way in C# to do so? I'd like to just have an event that triggers at this time. Is there a performance friendly way? I'd probably use a timer with an interval I calculate until it's 9am? Thanks!

❔ Get full namespace name

Hey, is there a way to get the full name of a namespace? E.g. nameof(DiscordBarista.Function.Partnership.Events) gives me "Events" but I want "Project_Sipster.DiscordBarista.Function.Partnership.Events" returned.

❔ Generalise Attributes?

Is there a way to generalise Attributes? I'd like to create a library in which I can just pass in what Enum to watch out for. So I'd like to replace the EPartnership/ECategory enum with any enum passed into the attribute. What would be the smartest way to get around this?

[AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]
public class EventPartnershipControllerAttribute : Attribute
{
    public EPartnership Event { get; set; }

    public EventPartnershipControllerAttribute(EPartnership Event)
    {
        this.Event = Event;
    }
}
public class EventController
    {
        [EventControllerAttribute(ECategory.PARTNERSHIP)]
        public static async void PartnershipController(string[] ids, object e)
        {
                    // Foo...

[AttributeUsage(AttributeTargets.Method, AllowMultiple = true)]
public class EventPartnershipControllerAttribute : Attribute
{
    public EPartnership Event { get; set; }

    public EventPartnershipControllerAttribute(EPartnership Event)
    {
        this.Event = Event;
    }
}
public class EventController
    {
        [EventControllerAttribute(ECategory.PARTNERSHIP)]
        public static async void PartnershipController(string[] ids, object e)
        {
                    // Foo...

❔ How to I use my domain for my ASP.NET REST?

Hi, question basically says it all. I don't have current application but I'm curious. I do have a domain on a webspace. So I'd host my application on a different Root Server. I am able to create Subdomains - how would I make my REST Application available from that subdomain?

❔ Can't use ToastContentBuilder.Show();

Hey, so I've created a WPF project in .NET 7.0 and wanted to use the Microsoft.Toolkit.Uwp.Notifications package with the ToastContentBuilder. I can't use the Show method for some reason. Documentation says that I should be on version 7.0 (using the newest one 7.1.3 (a downgrade didn't help either)), .NET 6 oder later and at least on net6.0-windows10.0.17763.0 or greater. Again, a downgrade didn't help here either. Someone got an idea?

var test = new ToastContentBuilder()
                .AddText("Hello world!");
            test.Show(); // Not found

var test = new ToastContentBuilder()
                .AddText("Hello world!");
            test.Show(); // Not found

❔ Is there a way to remove brackets from empty methods?

E.g.

public MismatchedEnumLengthsException() : base("Length of values and enums are different. You are required to pass as many values as there are enums")
{
}

public MismatchedEnumLengthsException() : base("Length of values and enums are different. You are required to pass as many values as there are enums")
{
}

I don't need those brackets. Can't I make this look prettier?

❔ Can I generalise this method?

public static IEnumerable<Enum> TransformIdToEnums(string value, params Type[] enums)
{
    string[] values = value.Split(',');
    for (int i = 0; i < enums.Length; i++)
    {
        var type = enums[i];
        yield return (Enum)Converter.GetEnumFromValue<type>(values[i]);
    }
}

public static IEnumerable<Enum> TransformIdToEnums(string value, params Type[] enums)
{
    string[] values = value.Split(',');
    for (int i = 0; i < enums.Length; i++)
    {
        var type = enums[i];
        yield return (Enum)Converter.GetEnumFromValue<type>(values[i]);
    }
}

Lets say I pass in "0,3,2" - I also want to pass in the Types of the Enusm I want to get them converted as. For example I split them into three different Enums, 0 being the category, 3 the subcategory and 2 a list item. Any way to generalise this?

❔ Is there any overview of useful attributes and how to use them?

E.g. [Obsolete] or for example where a method is allowed to be used and so on. Basically basic attributes for daily things that are included in common libs like System.
