internal class ClassHelper
{
    internal static string GetPropertyName<TClass, T>(Expression<Func<TClass, T>> propertyExpression)
    {
        if (propertyExpression == null)
            throw new ArgumentNullException("propertyExpression");
        var memberExpression = propertyExpression.Body as MemberExpression;
        if (memberExpression == null)
            throw new ArgumentException("Invalid argument", "propertyExpression");
        var propertyInfo = memberExpression.Member as PropertyInfo;
        if (propertyInfo == (PropertyInfo)null)
            throw new ArgumentException("Argument is not a property", "propertyExpression");
        else
            return propertyInfo.Name;
    }
}
