Get Property Name via Lambda Expression

To use it do something like GetPropertyName(()=>this.Property);

private string GetPropertyName<T>(Expression<Func<T>> property)
{
    var propertyInfo = (property.Body as MemberExpression).Member as PropertyInfo;
    if (propertyInfo == null)
    {
      throw new ArgumentException("The lambda expression 'property' should point to a valid Property");
    }
    var propertyName = propertyInfo.Name;
    return propertyName;
}

       /// <param name="firstClassElement">The first class element to serialize.</param>
       /// <returns>The XML string that represents the passed first class element.</returns>
