如何将货币字符串格式化为整数？ [英] How to format a Currency string to Integer?

问题描述

是否可以使用来检索， String.Format {}

解决方案

  int value = int .Parse（$ 35.00，NumberStyles.Currency）; 
  

应该给你你需要的答案。

<但是，像35.50这样的值转换为整数可能不会返回你想要的值，因为整数不支持部分（十进制）数字。你没有指定在这种情况下会发生什么。

如果您想在这种情况下获得35.5的值，您可能需要使用小数类型。

 十进制值= decimal.Parse（$ 35.00，NumberStyles.Currency）; 
  

请注意，在处理资金和浮动时，您必须非常小心点精度。

I'm have a string with currency format like $35.00 and this has to be converted to 35.

Is that possible to retrieve using String.Format{ }

解决方案

int value = int.Parse("$35.00", NumberStyles.Currency);

Should give you the answer you need.

However, a value like $35.50 converted to an integer will likely not return what you want it to, as Integers do not support partial (decimal) numbers. You didn't specify what to expect in that situation.

[EDIT: Changed double to decimal which is safer to use with currency]

If you want to get a value of 35.5 in that situation, you might want to use the decimal type.

decimal value = decimal.Parse("$35.00", NumberStyles.Currency);

Note that you have to be very careful when dealing with money and floating point precision.
