I am trying to convert my string variable to an integer to add a value (+1) to it but the result I get is:
1111
Infact I should be getting a total of 4 when I reconvert it to string.
What am I doing wrong?
public string str_Val = "1";
void Update () {
if (str_Val != "5") {
str_Val = int.Parse (str_Val + 1).ToString ();
}
}
It's all about the priority of the actions:
int.Parse (str_Val + 1)
In the row above first the addition happens str_Val + 1 outputing 11,111,111 etc.
Then the parsing occurs changing "11" to 11
Then to string occurs changing 11 to "11"
So change your code to
str_Val = (int.Parse(str_Val)+1).ToString();
This will first convert the string to int, then add two integers and finally convert the integer to string again.
you are concatenating 1 to the string before parsing, that is the reason of the behavior on your code...
so you are doing:
"1" + 1
"11"
Parse to int ("11")
convert to string(11)
do instead:
if (str_Val != "5")
{
str_Val = (int.Parse(str_Val) + 1).ToString ();
}
}
