Answer 1

Depending on your CultureInfo, it should work with the format string "N".

Check your CultureInfo.CurrentCulture.NumberFormat.NumberGroupSizes. If it is {3, 2, }, you are happy. So:

yourNumber.ToString("N")

You can give another culture if your current culture is not good, for example:

yourNumber.ToString("N", new CultureInfo("hi-IN"))

On my system, (121234567.89).ToString("N", new CultureInfo("hi-IN")) gives "12,12,34,567.89". Those are the group sizes you desire.

As you may know, formatting can also take place like this:

string.Format(new CultureInfo("hi-IN"), "The number {0:N} is well formatted", yourNumber)

Addition: Out of curiosity, I just tested which specific cultures on my system use the {3, 2, } number group sizes, and they are:

hi-IN
bn-IN
pa-IN
gu-IN
or-IN
ta-IN
te-IN
kn-IN
ml-IN
as-IN
mr-IN
sa-IN
kok-IN
si-LK
ne-NP
bn-BD
en-IN
