✅ Strange parsing error with docker instance

So I have a program that scrapes prices and parses them into longs with these lines of code

HttpResponseMessage page = await client.GetAsync({the link});

HttpResponseMessage page = await client.GetAsync({the link});

long itemCost = long.Parse(itemCostElement.TextContent, NumberStyles.AllowThousands | NumberStyles.AllowCurrencySymbol);

long itemCost = long.Parse(itemCostElement.TextContent, NumberStyles.AllowThousands | NumberStyles.AllowCurrencySymbol);

however I got this error

The input string '$79,156' was not in a correct format.

The input string '$79,156' was not in a correct format.

Is this because of unicode differences in linux that doesn't work well with docker images made in windows? The above code seems to work fine on my windows machine.

Probably a matter of system culture In some cultures, , is a decimal separator, in some it's a thousands separator, etc Could be that your dev culture is different from the prod culture

hm would something like

long itemCost = long.Parse(itemCostElement.TextContent, NumberStyles.AllowThousands | NumberStyles.AllowCurrencySymbol, CultureInfo.InvariantCulture);

long itemCost = long.Parse(itemCostElement.TextContent, NumberStyles.AllowThousands | NumberStyles.AllowCurrencySymbol, CultureInfo.InvariantCulture);

work then? ah yes tested with invariant Culture and returns the same error

Probably because invariant culture's currency symbol is ¤
