How to create a tiny dynamic information bar? In my projects for administrative mode I often use information panels and on-page tools. I used StringBuilder before, but it is not the most convenient approach, now I like the 4th option - to use List<string> and string.Join.

❌ 1. Crrraazy way
var crazyBar = "";
if (item.Title.Length != 0)
   crazyBar = item.Title;
if (item.CommentsCount > 0)
{
   if (crazyBar.Length != 0)
       crazyBar += " &bull; Comments (" + item.CommentsCount + ")";
   else
       crazyBar += "Comments (" + item.CommentsCount + ")";
}
if (crazyBar.Length != 0)
   crazyBar += " &bull; " + item.Date;
else
   crazyBar += item.Date;
Console.WriteLine(crazyBar);

❌ 2. Stupid way
var stupidBar = "";
if (!string.IsNullOrEmpty(item.Title))
   stupidBar = item.Title;
if (item.CommentsCount > 0)
   stupidBar += !string.IsNullOrEmpty(stupidBar) ? stupidBar + " &bull; Comments (" + item.CommentsCount + ")" : "";
stupidBar += !string.IsNullOrEmpty(stupidBar) ? stupidBar + " &bull; " + item.Date : item.Date;
Console.WriteLine(stupidBar);

❌ 3. Dumb way
var separator = "&bull;";
var dumbBar = new StringBuilder();
if (!string.IsNullOrEmpty(item.Title))
   dumbBar.Append(item.Title);
if (item.CommentsCount > 0)
   dumbBar.Append($"{(dumbBar.Length > 0 ? $" {separator} " : "")}Comments ({item.CommentsCount})");
dumbBar.Append($"{(dumbBar.Length > 0 ? $" {separator} " : "")}{item.Date}");
Console.WriteLine(dumbBar);

✅ 4. I prefer one of the perfect styles. Yeah!
var perfectBar = "";
var infoData = new List<string>();
if (!string.IsNullOrEmpty(item.Title))
   infoData.Add(item.Title);
if (item.CommentsCount > 0)
   infoData.Add($"Comments ({item.CommentsCount})");
infoData.Add(item.Date);
perfectBar = string.Join(" &bull; ", infoData).Trim();
Console.WriteLine(perfectBar);
