Convert.ToBoolean fails with “0” value

Question

I\'m trying to convert the value \"0\" ( System.String ) to its Boolean representation, like:

var myValue = Convert.To

Here's a very forgiving parser that keys off of the first character:

public static class StringHelpers
{
    /// 

    /// Convert string to boolean, in a forgiving way.
    /// 
    /// String that should either be "True", "False", "Yes", "No", "T", "F", "Y", "N", "1", "0"
    /// If the trimmed string is any of the legal values that can be construed as "true", it returns true; False otherwise;
    public static bool ToBoolFuzzy(this string stringVal)
    {
        string normalizedString = (stringVal?.Trim() ?? "false").ToLowerInvariant();
        bool result = (normalizedString.StartsWith("y") 
            || normalizedString.StartsWith("t")
            || normalizedString.StartsWith("1"));
        return result;
    }
}
