Convert string to currency format without casting to numerical value first
提问by ipr101
This code -
这段代码——
Convert.ToDecimal("28.9100000000000000").ToString("c")
will convert a string containing a decimal value to a nicely formatted currency value. Is there anyway to do this without first converting the string value to a decimal?
将包含十进制值的字符串转换为格式良好的货币值。无论如何，如果不先将字符串值转换为十进制，就可以这样做吗？

In order to preserve culture specific currency attributes (currency symbol, separators and precision), your current approach looks like the best one.
为了保留特定于文化的货币属性（货币符号、分隔符和精度），您当前的方法看起来是最好的方法。
If you know the precision and don't care about cultures, you can do some simple string manipulation:
如果你知道精度并且不关心文化，你可以做一些简单的字符串操作：
"$" & myString.Substring(0, myString.IndexOf(".") + 3)

A simple method that I use:
我使用的一个简单方法：
MoneyString = string.format("{0:C}",DecimalValue)

How about this?
这个怎么样？
decimalString = "28.910000000000000000"
currencyString = "$" + decimalString.SubString(0, decimalString.IndexOf('.') + 3)
Of course, if you're going to do this you also need to worry about locale settings. Probably just as easy to do the numeric conversion, and let the framework do the formatting for you.
当然，如果您打算这样做，您还需要担心区域设置。进行数字转换可能同样容易，让框架为您进行格式化。
