Question

Example –

textbox.Text = "456/789"; 
var nominator = 456; 
var denominator = 789

How could I code this in c# ?

1. Also, how could I make one number from elements of array. For example, {1,5,7,6} would become 1576.

And now, i have such bad idea, but i wont to know: if I have int number in nominator, I will do one method from my1.cs, if I have double number in nominator/denominator I will do method from another class called my2.cs . How I may code IF, if (number = int;bla bla bla…), if (number = double; bla bla bla…)

Answer 1

Something like:

1.

string[] numdenom = textbox.Text.Split('/');
var numerator = numdenom[0];
var denominator = numdenom[1];

2.

string[] digits = new string[] { "1","5","7","6" };
string number = string.Join(string.Empty, digits);
int numberValue = int.Parse(number); // or int.TryParse if you prefer
