Modifying WebHook Message With Discord.Net c#

Question

 using (DiscordWebhookClient client = new DiscordWebhookClient(WEBHOOK_URL))
{
   ulong z = 42342340290226;

   client.ModifyMessageAsync(z);//Not sure how I would edit this message. The documentation is confusing.
}

Im not sure how to use this ModifyMessage function. Also, do I need to use a Async Function? I am just calling it without using any ASYNC. Im not sure if that is ok. The send message works, but second function im not sure how to work it.

Answer 1

Like others have said, you should await the async call. This ensures that the action is executed in a predictable fashion. The intend is to execute it right now and to wait for the result of the action.

That being said, the discord documentation describes this method as follows:

public Task ModifyMessageAsync(ulong messageId, Action<WebhookMessageProperties> func, RequestOptions options = null)

The second parameter describes a delegate based on WebhookMessageProperties. It can easily be defined by a lambda, like such:

x => { }

Now bear in mind the x is arbitrary, you can chose whatever designation you like, even whole words, I just kept it short for the example.

Between the bracelets, you can use access any properties that are in the WebhookMessageProperties class, by using x.SomeProperty. Where SomeProperty has to be a known property of that class if that makes sense.

One of the known properties is for example:

string Content { get; set; }

So here is how you can use a lambda to change the Content property:

using (DiscordWebhookClient client = new DiscordWebhookClient(WEBHOOK_URL))
{
    ulong z = 42342340290226;

    await client.ModifyMessageAsync(z, x => 
    {
        x.Content = "This is the updated message content";
    });

}

If you want to update multiple properties at the same time, you can just add another line inside the lambda.
