Custom value mapping

When mapping a value from an object's property it may be desirable to format the value prior to it being added to the dictionary. The following example shows a simple value mapper that will format a date time as dd-MMM-yyyy

Note

The propertyInfo parameter passed into the delegate provides full information about the property whose value will be added to the dictionary.

The value parameter is the value of the property.

var dictionary = new MyObject()
    .ToDictionary(c => c
        .WithValueMapper((propertyInfo, value) => value switch
        {
            DateTime dateValue => dateValue.ToString("dd-MMM-yyyy"),
            _ => value                      
        }));

// Any DateTime properties will be formatted as configured above.
// e.g. 12-Mar-2010 for DateTime(2010, 3, 12)
