字符串到十进制解析 C#

Question

I am trying to parse or convert a string to decimal in C#.

I need to be able to parse strings like,

$123,345,676.8999 to its equivalent 123345676.90.

I need to have only 2 places after the decimal point and that needs to be suitably rounded.

Can you guys please suggest a way to do the above? Basically, any string in the form of currency (with $,pound symbol etc). I should be able to parse it and convert it to decimal.

Answer 1

Try this:

var val = double.Parse("$123,345,676.8999", NumberStyles.AllowThousands | NumberStyles.AllowDecimalPoint | NumberStyles.AllowCurrencySymbol);
val = Math.Round(val, 2);

Answer 2

您可以使用decimal.TryParse来执行解析——链接中有一些关于解析如何工作的示例。
