示例1: TryReadValues
/// <summary>
/// Reads the values from an <see cref="IDataReader"/> and assigns the read values to this
/// object's properties. Unlike ReadValues(), this method not only doesn't require
/// all values to be in the <see cref="IDataReader"/>, but also does not require the values in
/// the <see cref="IDataReader"/> to be a defined field for the table this class represents.
/// Because of this, you need to be careful when using this method because values
/// can easily be skipped without any indication.
/// </summary>
/// <param name="source">The object to add the extension method to.</param>
/// <param name="dataRecord">The <see cref="IDataReader"/> to read the values from. Must already be ready to be read from.</param>
