我通常会使用它:
double test = 1234.5678;
Console.WriteLine(test.ToString("C"));
效果很好。我有一个"覆盖"为加拿大元确保人们会看到美元和加元之间的差异:
var canadaFi = (NumberFormatInfo)CultureInfo.GetCultureInfo("en-CA").NumberFormat.Clone();
canadaFi.CurrencySymbol = "C$ ";
Console.WriteLine(val.ToString("C", canadaFi));
但是现在人们都在问输出:
CAD 1234,56
所以我用过:
RegionInfo ca = new RegionInfo("en-CA");
Console.WriteLine(string.Format("{0} {1}", ca.ISOCurrencySymbol, test.ToString("f2")));
哪个有效,但我想知道如果这是最好的方法在float / double前面获得3个char iso货币符号。
那么我现在不必使用CultureInfo
而是使用RegionInfo
吗?

正确的方法是:
const string canada = "en-CA";
var ca = new RegionInfo(canada);
var cai = new CultureInfo(canada)
{
NumberFormat =
{
CurrencySymbol = ca.ISOCurrencySymbol,
CurrencyPositivePattern = 2,
CurrencyNegativePattern = 12
}
};
Console.WriteLine(test.ToString("C", cai));
如果设置CurrencyPositivePattern = 2
,请确保该符号位于数字前面,并带有额外的空格(另请参阅documentation for CurrencyPositivePattern),CurrencyNegativePattern = 12
对负值执行相同操作(documentation for CurrencyNegativePattern)。
输出:
CAD 1,234.57
和负面
CAD -1,234.57

正如@Corak所解释的那样:
CultureInfo cai = new CultureInfo("en-CA");
RegionInfo ca = new RegionInfo("en-CA");
Console.WriteLine(ca.ISOCurrencySymbol + " " + test.ToString("C", cai).Substring(1));
输出:
CAD 1,234.57
@Coraks建议补充道:
Console.WriteLine(ca.ISOCurrencySymbol + " " + test.ToString("C", cai).Replace(cai.CurrencySymbol, ""));
