C#| 使用String.Format()方法使用千位分隔符打印浮点数

要打印带有一千个分隔符的浮点数，我们可以使用method，这是示例。String.Format()

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //千位分隔符
            Console.WriteLine("Thousand Separators");
            
            Console.WriteLine(String.Format("{0:0,0.0}", 9876.67));     
            Console.WriteLine(String.Format("{0:0,0}", 9876.67));
            Console.WriteLine(String.Format("{0:0,0.0}", 987654321.67));
            Console.WriteLine(String.Format("{0:0,0}", 987654321.67));

            Console.WriteLine();  
        }
    }
}

输出结果

Thousand Separators
9,876.7
9,877
987,654,321.7
987,654,322
