如何从数据库格式化货币

Question

The goal

I want to format correctly the currency from database.

The problem

I'm formatting the currency from database with this:

@String.Format("{0:C}", @Model["MinProductPrice"])

The problem is: 150 have to be 1,50 , and not 150,00 — and this formatting is doing this.

What is the right formatting type to my case?

Answer 1

您可能想先将数字除以100（请记住要更改类型），因此150变为1.50 ，根据语言环境，该值将转换为"1,50" ：

@String.Format("{0:C}", @Model["MinProductPrice"] / 100.0m)

Answer 2

I'll extend my comments into an answer, I think that's more appropriate. I think you should change the column type to a money or decimal type to prevent bugs by making the use of the column more obvious. Your output on your page will be correct and won't require any "magic numbers" to get it to print out properly.

Just a note but you can also print a currency string doing this:

@Model["MinProductPrice"].ToString("C")

Answer 3

I attributed the casting responsibility to database. I'm using MySQL and the query is like this:

ROUND(CAST(MIN(`map`.`Product_Price`) AS DECIMAL)/100,2) as `minProductPrice`

Anyway, I would to thanks jlafay and csharpler about their answers — they were very helpful and worked well for me.
