Question

For instance, let s say I have the DateTime format-string in a string variable, is there any syntax or method in .NET that would let me do the equivalent of this invalid code:

String line = String.Format("{0:{1}}", DateTime.Now, dateTimeFormat);
                                ^^^                        ^
                                 |                         |
                                 +-- this would use this --+

Answer 1

I think this syntax overview pretty much excludes dynamic parameters.

You will have to use a 2 stage system somehow, either pre-formatting your Date or by generating a format string. But I think both will be worse than the problem.

Answer 2

What s wrong with just

string line = DateTime.Now.ToString(dateTimeFormat);

?
