推荐答案
如果你正在处理一个长
号码,你可以使用<一个href=\"http://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo.aspx\"><$c$c>NumberFormatInfo$c$c>对其进行格式化:
If you're dealing with a long
number, you can use a NumberFormatInfo
to format it:
首先,定义你的NumberFormatInfo(您可能需要额外的参数,这些都是基本3):
First, define your NumberFormatInfo (you may want additional parameters, these are the basic 3):
NumberFormatInfo format = new NumberFormatInfo();
format.NumberGroupSeparator = "-";
format.NumberGroupSizes = new[] { 4 };
format.NumberDecimalDigits = 0;
接下来,你可以用它在你的号码:
Next, you can use it on your numbers:
long number = 731478718861993983;
string formatted = number.ToString("n", format);
Console.WriteLine(formatted);
