C# float.tryparse for French Culture

Question

I have a user input which can contain float values ranging from : 3.06 OR 3,06 The culture we are in is French and thus when the user inputs 3.06 and I run a float.tryParse

Answer 1

float usedAmount;

// try parsing with "fr-FR" first
bool success = float.TryParse(inputUsedAmount.Value,
                              NumberStyles.Float | NumberStyles.AllowThousands,
                              CultureInfo.GetCultureInfo("fr-FR"),
                              out usedAmount);

if (!success)
{
    // parsing with "fr-FR" failed so try parsing with InvariantCulture
    success = float.TryParse(inputUsedAmount.Value,
                             NumberStyles.Float | NumberStyles.AllowThousands,
                             CultureInfo.InvariantCulture,
                             out usedAmount);
}

if (!success)
{
    // parsing failed with both "fr-FR" and InvariantCulture
}
