Can .NET convert “Yes” & “No” to boolean without If?

Question

You would think there would be a way using DirectCast, TryCast, CType etc but all of them seem to choke on it e.g.:

CType(\"Yes\", Boolean)

Answer 1

public static bool IsBoolean(string strValue)
{
    return !string.IsNullOrEmpty(strValue) && ("1/YES/TRUE".IndexOf(strValue, StringComparison.CurrentCultureIgnoreCase) >= 0);
}
