This method returns a number
It doesn't convert in place
After all,
age is a stringBut I converted it
And it can only ever remain a string, it can only ever hold a string, it cannot, under any circumstance, hold an integer
Convert.ToInt32() RETURNS a number
It doesn't change the variable you passedReturns to where?
Just... returns
To the left of it, let's say
Like any method that returns anything
But I want my string to be an int
age was declared as a string, so it can only ever be a string
You need a new variable
An int type variableThen whats convert even for?
For... converting a string into an int, in this case?
I mean, it does what you expect it to
You said it doesnt convert
Just returns
It converts the string into an integer and returns that integer
Yeah
As I said, C# is statically and strictly typed
But it doesnt work
A variable cannot change its type
It doesn't work because you're using it wrong

You're not using what the method returns
Simple as
You said 2 opposite things
I didn't?
The method doesn't change the type of any variable?
What method
Im just using main

And, really, go through the linked tutorials
You need to know the type system
You need to know what methods are
What type system

That types in C# are strict and static and what it means, for example
I know what methods are
And Im using only main
I just want my string to be an int but it shows error
Why is this int number empty?
Why would it be?
It's not empty
It's... not empty?
So you did convert that string after all
Yes?
But you said I can't
You can't convert IN PLACE
What place?
Wdym?
is NOT THE SAME as
you can't change the type of age
Variable
text is STILL a string, and it STILL holds the value "420"
Variable number is NEW and its type is int
The method converted the value and assigned it to a new variable
The old variable remains wholly and entirely unchanged"wholly and entirely unchanged"
very descriptive
They just said I cant
I have to make new variable
yes it's normal
Yes what?
age is define as a string you have to create a new variable to have an int
So I cant change its type like you said
you missed a t in
cant
thxOk so variable is always same type and I have to make a new one with the same value for it to work
