C# serialize decimal to xml

Question

I got a decimal property, like

[XmlElementAttribute(DataType = "decimal")] decimal Price

The problem is that I wanna force it to serialize always with precision of 2, but if the price is 10.50 it will be serialized to XML like <Price>10.5</Price>.

Theres any way to force it (without creating a new property or changing the get of this property? I'm looking for some way to do this only sending a pattern to the XmlSerializer (or the XmlElementAttribute) or any smart way to do this ?

Thanks

Answer 1

I was having the opposite problem. My decimals were serializing with 4 decimal places, even though they were all 4 zeroes. I discovered that if I call decimal.Round(value, 2) then it serializes to 2 decimal places. It would appear that the Decimal type remembers what you last rounded it too when it is serialized.

I was suspicious of the suggestion, but it worked that simply. Even though the value didn't need rounding, calling Round changed how many decimal places showed up in serialization.
