C# - Format float WITHOUT tail zeros

Question

Is that possible in C# to format

4.52 float number to 4.52 string

and

4.520 float number to 4.52 string, i.e. omitting tail zeros?

EDIT: I think I've not accented the real problem. I need ONE pattern that conforms BOTH of the above examples!

Answer 1

Assuming you want to omit any trailing 0's from your value, this should give you what you want:

ToString("0.####")

Otherwise you could do:

ToString("0.00##")
