格式货币字符串到整数 [英] Format Currency string to integer

问题描述

我已经用货币格式类似$ 35.00，这已被转换为35。谁能帮助一个字符串？这是可能使用的String.Format {}

解决方案

  int值= INT检索。解析（$ 35.00，NumberStyles.Currency）; 
  

应该给你你需要的答案。

然而，像$ 35.50的值转换成整数可能不会回报你希望它是什么，因为整数不支持部分数（十进制）。你没有指定在这种情况下会发生什么

如果你想在这种情况下获得的35.5值，你可能想使用十进制类型。

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

请注意，您必须非常用金钱和浮动打交道时谨慎点精度。

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