Question

I am taking numerical input from a text box. I want to check

if(textBox1.Text.Contains("."))

like 55.37

then split the string in two parts/strings.

1. First part before period (55)
2. Second part after the period (37)

Answer 1

Use this:

string[] ret = textBox1.Text.Split('.');

Then you can do

if (ret.Length != 2) // error ?!?

ret[0] is integer part
ret[1] is fractional part
