**To display custom formatting for zero and negative numbers, we can use String.Format() in C\#, here is the example.**

**要显示零和负数的自定义格式，我们可以在C＃中使用String.Format()，这是示例。**

using System;
    
    namespace ConsoleApplication1
    {
        
        class Program
        {
        
            static void Main(string[] args)
            {
        
                Console.WriteLine("Demo for custom formatting for zero and negative number");
    
                Console.WriteLine(String.Format("{0:0.00;minus 0.00;zero}", 512.4567));  
                Console.WriteLine(String.Format("{0:0.00;minus 0.00;zero}", -512.4567)); 
                Console.WriteLine(String.Format("{0:0.00;minus 0.00;zero}", 0.0));       
    
                Console.WriteLine();  
            }
        }
    }

**Output**

**输出量**

Demo for custom formatting for zero and negative number
    512.46
    minus 512.46
    zero

In the above program, there are three sections separated by semicolon,

在以上程序中，用分号分隔了三个部分，

*  First for positive number
    
    首先为正数
 *  Second for negative number
    
    负数第二
 *  Third for zero
    
    第三为零
