I'm studying c# from Linkedin Learning, and in a lesson, the professor code worked great in the video, but the exact same file doesn't work for me, returning the error:
Input string was not in a correct format.
This is the code that doesnt work:
using System;
using System.Globalization;
namespace Parsing {
class Program
{
static void Main(string[] args)
{
string numStr = "2.00";
int targetNum=0;
try {
targetNum = int.Parse(numStr, NumberStyles.Float);
Console.WriteLine(targetNum);
}
catch(Exception e) {
Console.Write(e.Message);
}
bool succeeded = false;
if (succeeded) {
Console.WriteLine($"{targetNum}");
}
}
}
}
This, however, does work:
using System;
using System.Globalization;
namespace Parsing {
class Program
{
static void Main(string[] args)
{
string numStr = "2";
int targetNum=0;
try {
targetNum = int.Parse(numStr, NumberStyles.Float);
Console.WriteLine(targetNum);
}
catch(Exception e) {
Console.Write(e.Message);
}
bool succeeded = false;
if (succeeded) {
Console.WriteLine($"{targetNum}");
}
}
}
}
Anyone have a light to shine on why the other code doesn't work?
Your profile says you're based in Brazil and in Brazil "two and a half" is "2,5", not "2.5".
If you run your code with "2,00" it should work.
Here's an example with different cultures:
foreach(var two in new []{"2.00", "2,00"})
foreach(var culture in new []{"pt-BR", "en-AU"})
{
bool ok = int.TryParse(two, System.Globalization.NumberStyles.Float, new System.Globalization.CultureInfo(culture), out var i);
Console.WriteLine($"For '{culture}' '{two}' is {(ok ? "OK" : "not OK")}");
}
This prints:
For 'pt-BR' '2.00' is not OK
For 'en-AU' '2.00' is OK
For 'pt-BR' '2,00' is OK
For 'en-AU' '2,00' is not OK
