Question

In C#, I have a situation where I have two possible numbers in a textbox control.

The numbers can be either:

a) .xxxx

or

b) .xx

How do I write a condition that says, “If the textbox has 4 decimal places, then call this function, otherwise, if the textbox has 2 decimal places, then call this function.”

Seems easy, but I don’t know how to evaluate the decimal places.

Thanks much!

You can use Regex

new Regex(@"\.\d{2}$").IsMatch(input.Value)
