Cast Char to String.

[AdamSpeight2008]

Would it be beneficial to have a Char to be cast-able to a String?
You could think of it as a String of one character in length.

As an implicit conversion? Certainly not, that can lead to unnecessary string allocations.

As an explicit conversion? Maybe, but it's not different from calling ToString() and, at least in my experience, rarely necessary.

In practice, you can do:

"" + c

rather than :

c.ToString()

So I'm not sure that:

(string)c

would be a worthwhile improvement.

However, $c would be a nice shorthand for $"{c}" and it needn't be limited to character expressions.

You're not implying those are the same thing. Are you?

[alanfo]

If I've understood string interpolation correctly, then $"{c}" is the same thing as c.ToString().

If it were considered desirable to have a shorter way of converting a char to a string (rather than use hacks such as "" + c), then I was thinking that $c might be a better proposal than a cast.

It also occurred to me that this syntax needn't be limited to converting character expressions to strings - you could convert other types as well - and could be thought of as a shorthand for $"{c}".

No it isn't.
