转换负十进制字符串丢失 - [英] Converting Negative Decimal To String Loses the -

问题描述

我需要负myDecimalValue.ToString（C）发送;问题是如果myDecimalValue为负，可以说-39，我越来越$ 39.00为字符串不是$ 39.00转换后。所以，我不知道如何去这一点。

I'm required to send in a negative myDecimalValue.ToString("C"); The problem is if myDecimalValue is a negative, lets say -39, after conversion I'm getting $39.00 as the string not $39.00. So I'm not sure how to go about this.

这是工具方法，发生在小数。如果小数点是负的，我要的ToString显示负

This is the utility method that takes in the decimal. If the decimal is negative, I want the ToString to show a negative

    public static BasicAmountType CreateBasicAmount(string amount, CurrencyCodeType currencyType)
    {
        BasicAmountType basicAmount = new BasicAmountType
                                          {
                                              currencyID = currencyType,
                                              Value = amount
                                          };
        return basicAmount;
    }

我可能会有两种方式，C或F2，我才不管是关于得到那个负号施行本科生字符串，如果输入十进制为负。我想，有没有办法做到这一点，除非我检查我的消极实用方法里面在这里。我不能只是给一个负数，并期望的ToString工作，为的ToString自动看到小数点为负传入？

I could go either way, a C or F2, all I care is about getting that negative sign intothe string if the incoming decimal is negative. I suppose there's no way to do this unless I check for negativity inside my utility method here. I can't just send a negative number and expect the ToString to work and for the ToSTring to automatically see that the decimal is negative incoming?

推荐答案

您可以试试这个：

decimal myDecimalValue = -39m;
string s = String.Format("${0:0.00}", myDecimalValue); // $-39.00

不过，SLaks是正确的，负值通常在括号中。

However, SLaks is right, negative values are usually shown in parenthesis.
