How to get the nickname of the author of the message in the discord using Discord.net 2.2.0 C#

Question

How can I get the nickname of the author of the message in Discord using Discord.net 2.2.0.

private async Task MessageReceivedAsync(SocketMessage message)
{
    if (StartBit == 0)
    { 
    await message.Channel.SendMessageAsync("Test");
    }
    StartBit = 1;
    // The bot should never respond to itself.
    if (message.Author.Id == _client.CurrentUser.Id)
        return;
    var UName = message.Author.Username;
    var UID = message.Author.Id;
}

A long search and reading of the documentation unfortunately gave me nothing.

If you want to get the authors nick name you can cast it to SocketGuildUser, but beware, it can be null if it's a DM.

var UNick = (message.Author as SocketGuildUser).Nickname;

Also you probably should check if the message is from a user and not system

if (!(sockMessage is SocketUserMessage msg))
    return;

So your code will look something like this

private async Task MessageReceivedAsync(SocketMessage sockMessage) 
{ 
    // Check if a user posted the message
    if (!(sockMessage is SocketUserMessage msg))
        return;

    // Check if it is not a DM
    if (!(msg.Author as SocketGuildUser author))
        return;

    if (StartBit == 0) 
    { 
        await msg.Channel.SendMessageAsync("Test");
    }

    StartBit = 1; 

    // I usualy check if the author is not bot, but you can change that back
    if (msg.Author.IsBot) 
        return; 

    var UName = author.Username; 
    var UNick = author.Nickname;
    var UID = author.Id;
}

Try casting your message to an SocketUserMessage. I have attached the correct code for that and please edit your post, so that the code is presented correctly.

private async Task MessageReceivedAsync(SocketMessage msg) 
{ 
    SocketUserMessage message = msg as SocketUserMessage;

    if (StartBit == 0) 
    { 
        await message.Channel.SendMessageAsync("Test");
    } 
    StartBit = 1; 

    // The bot should never respond to itself.
    if (message.Author.Id == _client.CurrentUser.Id) return; 

    var UName = message.Author.Username; 
    var UID = message.Author.Id; 

}
