c# - ne peut pas accéder à la chaîne dans un corps de méthode - Stack Overflow

The code that I have

private bool isValidNumber(string myString)
{
    const int VALID_LENGHT = 10;
    bool valid = true;
    if (myString.Lenght == VALID_LENGHT)
    {
        foreach (char ch in myString)
        {
            if (!char.IsDigit(ch))
            {
                valid = false;
            }
        }
    }
    else
    {
        valid = false;
    }
    return valid;
}

And the error that I have when I tried to check myString.Lenght

Error 1 'string' does not contain a definition for 'Lenght' and no extension method 'Lenght' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)

It's spelled "Length" not "Lenght".

Problem : Error is straight forward there is no Lenght property for in string class.

Solution : you just need to replace Lenght with Length

Replace This:

if (myString.Lenght == VALID_LENGHT)

With This:

if (myString.Length == VALID_LENGHT)

The code that I have

private bool isValidNumber(string myString)
{
    const int VALID_LENGHT = 10;
    bool valid = true;
    if (myString.Lenght == VALID_LENGHT)
    {
        foreach (char ch in myString)
        {
            if (!char.IsDigit(ch))
            {
                valid = false;
            }
        }
    }
    else
    {
        valid = false;
    }
    return valid;
}
