Padding a string with integers on its right keeping string length fixed

[Richard Deeming]

Even simpler:

string x = string.Format("T{0:D5}", number);

Or:

string x = $"T{number:D5}";

isn't the "$" notation for PHP or some other stupid language? Or is it a new pointless operator in C#?

It's been a C# feature since v6: $ - string interpolation - C# reference | Microsoft Docs[^] What's New in C# 6 - C# Guide | Microsoft Docs[^]

Let's obfuscate C# even more than it already is...

String interpolation was a pretty good addition, IMO. Especially when you compare it to the abomination that became of default interface methods[^]. X|

I agree - I use string interpolation precisely because it de-obfuscates code:

Console.WriteLine("({2},{1}):({0},{3})={4}", destX, y, x, destY, dist);

Isn't as obvious as

Console.WriteLine($"({x},{y}):({destX},{destY})={dist}");

Except when you use random ordering of your variables. ;P

:laugh: I've seen code like that before: when the variable list order is wrong, and it was easier to renumber than juggle the names ... Not that I'd write code like that, oh no.

For me, the numbers have to be in order, so I juggle the names. :)

A legitimate use case for unordered variables might be when writing output in different languages. In one language you might want to write "Page 1 of 10", but in another it might be "10 pages, No. 1" or some such. You would read the template from the resource file, filling in the values as necessary.
