C# 在给定IFormatProvider的情况下应用千位分隔符，就像小数点一样

下面的代码适用于十进制分隔符，这意味着，对于pt，它呈现“，”而对于en-us，它呈现“

如何使用千位分隔符实现相同的行为

        decimal dec = Convert.ToDecimal(20000.01);

        IFormatProvider portuguese = new System.Globalization.CultureInfo("pt-pt");
        IFormatProvider english = new System.Globalization.CultureInfo("en-us");

        Console.WriteLine(dec.ToString(portuguese));
        Console.WriteLine(dec.ToString(english));

无可否认，这是一次无中生有的尝试

decimal dec = Convert.ToDecimal(20000.01);

IFormatProvider portuguese = new System.Globalization.CultureInfo("pt-pt");
IFormatProvider english = new System.Globalization.CultureInfo("en-us");

Console.WriteLine(dec.ToString({0:C},portuguese)); //tell it that its currency
Console.WriteLine(dec.ToString(({0:C},english));   //tell it that its currency

您需要使用包含千位分隔符的格式字符串

例如：a：

您可以通过

M

后缀：

decimal-dec=20000.01M

创建十进制值。您可以通过

M

后缀：

decimal-dec=20000.01M

dec.ToString("#,###.00", portuguese);
