Selectivly choose from user input?
If I have the Console.ReadLine() method, and I want to separate between int and string whatever the user writes (or whatever I want to take from it), is it possible? For example: User imputs: "Age is 23", can I separate the string "Age is..." from "23" and turn the last one into an integer?

if u convert text value to int and it have a alphabetic data or anything expect number it show error
text=1234
int=1234
---
text=1234a
int=error

You can probably use int.TryParse method to get int from a string without running into error.
But if you need to parse the string you should use string.indexof() to find specific characters.

well, you can do that.
You can first do the int.TryParse,
get the int in the string,
then do a search on the inputted string to get the position of the int in the string,
then u can just trim off the string to that position.
i believe this should work.

Thanks! Also, can I asign 2 variables like this:
string text = (whatever he wrote)
int age = (the conversion to int)
And then just work with them that way?

when u get a number convert it to int
int i=convert.toint(console.read( ) );
then u can add
string str="age is"+i.tostring( ) ;
or if u instead get int number in string value
u can use diferent ways like get it from char index
every string value is array of chars it began from 0 to string length-1 or use split command or other ways

you must have 3 or 4 variable one of them is for string one & of them for int another one for char(to get char code and find whom char is number or string)
step 1=input_variable(string)
step 2=get string text length
step 3=repeat cycle by text length
step 4=get 1 character of input_variable and convert it to char
step 5=char_variable and main function(most important. depend on what charcode is it find it is number or not )
step 6= you can use temporary stringvariable then convert it to int or define what char equal than what number is
step 7 =as you want.as you wish

Need separate age from text just by char code and char index
