Casting Y or N to bool C#

Question

Just for neatness sake I was wondering, whether it\'s possible to cast Y or N to a bool? Something like this;

bool theanswer = Convert.ToBoolean(input);

Wonea gave an "IsTrue" source example from DotNetPerls. Here are two shorter versions of it:

public static bool IsTrue(string value)
{
    // Avoid exceptions
    if (value == null)
        return false;

    // Remove whitespace from string and lowercase it.
    value = value.Trim().ToLower();

    return value == "true"
        || value == "t"
        || value == "1"
        || value == "yes"
        || value == "y";
}

OR:

private static readonly IReadOnlyCollection LOWER_TRUE_VALUES = new string[] { "true", "t", "1", "yes", "y" };

public static bool IsTrue(string value)
{
    return value != null
        ? LOWER_TRUE_VALUES.Contains(value.Trim().ToLower())
        : false;
}

Heck, if you want to get real short (and ugly), you can collapse that down to two lines like this:

private static readonly IReadOnlyCollection LOWER_TRUE_VALUES = new string[] { "true", "t", "1", "yes", "y" };
public static bool IsTrue(string value) => value != null ? LOWER_TRUE_VALUES.Contains(value.Trim().ToLower()) : false;
