Hey, I'm trying to get into C# so please excuse me for being a noob! I'm trying to create a chat command that would work like this:

/consoleCMD <SteamID>

-This would then make the specified player run some code like this,  player.Command("echo \"Hello\"")

		 [ChatCommand("runcmd")]
         private void runcmdCommand(BasePlayer player, string command, string[] args)
		 {
			var steamID = Interface.Oxide.GetLibrary<Covalence>().Players.FindPlayerById("userIdAsString");
			
			if (args == null || args.Length == 0)
                {
                    SendReply(player, "Syntax: /runcmd <STEAMID>");
                    return;
                }
			switch (args[0].ToLower())
			{
                    case steamID:
                        SendReply(player, "TEST");
                        return;
                    default:
                        break; 
            }
		 }

[Command("runcmd")]
private void RunCommand(IPlayer player, string command, string[] args)
{
    if (args.Length == 0)
    {
        player.Reply("Syntax: /runcmd <STEAMID>");
        return
    }

    IPlayer targetPlayer = players.FindPlayerById(args[0]);
    if (targetPlayer != null)
    {
        targetPlayer.Command("echo \"hello world\"");
    }
}​

This assumes your plugin is set as a RustPlugin (not recommend, being replaced by CovalencePlugin):

[Command("runcmd")]
private void RunCommand(BasePlayer player, string command, string[] args)
{
    if (args.Length == 0)
    {
        SendReply(player, "Syntax: /runcmd <STEAMID>");
        return
    }

    IPlayer targetPlayer = covalence.Players.FindPlayerById(args[0]);
    if (targetPlayer != null)
    {
        targetPlayer.Command("echo \"hello world\"");
    }
}

Hey thanks for the help, not sure why but when I try to load the plugin it returns this error:

Error while compiling: Plugin.cs(30,4): error CS1056: Unexpected character `​'

the line 30,4 doesn't exist though so im not sure how to fix this one

Edit: This error is from the covalence sample you provided

Yeah for some reason my plugin had an invisible character in it somewhere, the code works great but when I try to use this:

var pos = (targetPlayer.transform.position);

I get this error:

Error CS1061 'IPlayer' does not contain a definition for 'transform' and no accessible extension method 'transform' accepting a first argument of type 'IPlayer' could be found (are you missing a using directive or an assembly reference?)

For reference I'm trying to do this: 

        [Command("runcmd")]
        private void RunCommand(IPlayer player, string command, string[] args)
        {
            if (args.Length == 0)
            {
                player.Reply("Syntax: /runcmd <STEAMID>");
                return;

            }

            IPlayer targetPlayer = players.FindPlayerById(args[0]);
            if (targetPlayer != null)
            {
                var pos = (targetPlayer.transform.position);
                pos.y += 1.5f;
                targetPlayer.Command("ddraw.text 15 255,0,0 ", pos, " Hey q t :p");
            }
        }
