easy way to format numbers to strings?

Question

In C#, I'd like to convert some numbers to strings in a standard format, but preferably in a simple way, such as if you were going to output them rather than store them in string variables, a la:

Console.WriteLine ("{0:F2}", num);

rather than use a bunch or string methods to make them all the same number of significant digits. Isn't there any way to do this?

you can make use of the string.format(yourformat yourvalue); method

If you find yourself using the same formatting string over and over you might want to declare a const string and use that string variable in your ToString() or String.Format() calls. In that case you would only need to change the format string in one place if the format needed to change.

John Penn · Answer

The default ToString() method of each numeric type will give you the string representation of the value but without any formatting. Formatting requires the use of formatting strings which is probably the most straightforward way to get them into a particular format.
