Product Object Class - C#

A DLL is to be developed in C#. All requirements must be met before the project is considered to be complete. The Product class will be based on a datasource that contains unit conversion data that is easily expandable for future conversion change requirements. Conversions between units will be supported where appropriate. Currency conversion rates should be up-to-date, probably based on a web service that provides the accurate exchange rates. Comparisons must be publicly accessible and work between units. Product objects should contain a price and a unit. Product objects need to be able to support comparison operators. One must be able to determine which product object is cheaper and which one is more expensive. The main goal is to have a product object available that contains a unit, price, and quantity. These product objects must be comparable so that one can determine which product is cheaper, as long as the units are comparable. You may need to create an IsComparable method. All measurement units must be supported. Including cooking measurements. US measurement system and Metric system must be supported. ## Deliverables * All measurement units must be supported. Including cooking measurements. US measurement system and Metric system must be supported. 1. [length][1] 2. [mass][2] 3. [time][3] 4. [Cooking][4] 5. Volume 6. [thermodynamic temperature][5] 7. [luminous intensity][6] 8. [electric current][7] 9. [amount of substance][8] 10. currency * All unit prefixes must be supported. Sample prefixes are listed in the following chart. 1. <caption>[Standard prefixes for the SI units of measure][9]</caption> | Multiples | Name | | [deca-][10] | [hecto-][11] | [kilo-][12] | [mega-][13] | [giga-][14] | [tera-][15] | [peta-][16] | [exa-][17] | [zetta-][18] | [yotta-][19] | | ------------ | ---- | ---- | ----------- | ------------ | ------------ | ------------ | ----------- | ----------- | ------------ | ----------- | ------------ | ------------ | | Symbol | | da | h | k | M | G | T | P | E | Z | Y | | Factor | 10 | 101 | 102 | 103 | 106 | 109 | 1012 | 1015 | 1018 | 1021 | 1024 | | | | Subdivisions | Name | | [deci-][20] | [centi-][21] | [milli-][22] | [micro-][23] | [nano-][24] | [pico-][25] | [femto-][26] | [atto-][27] | [zepto-][28] | [yocto-][29] | | Symbol | | d | c | m | µ | n | p | f | a | z | y | | Factor | 10 | 10-1 | 10-2 | 10-3 | 10-6 | 10-9 | 10-12 | 10-15 | 10-18 | 10-21 | 10-24 | * Datasource 1. The datasource should be either a database or an xml file. Other datasource suggestions will also be considered. 2.
