The function of escape character and @ symbol in 11.c#

Escape character escape character refers to a ' \ ' + a special character, consisting of a character with a special meaning. \ n: Represents a newline.

  
 

   
  

  
namespace _11.转义符
   
  

  
{
   
  

  
 class Program
   
  

  
 {
   
  

  
 static void Main(string[] args)
   
  

  
 {
   
  

  
 Console.WriteLine("窗前明月光,\n疑是地上霜.\n举头望明月,\n低头思故乡.");
   
  

  
 Console.ReadKey();
   
  

  
 }
   
  

  
 }
   
  

  
}
  
 

Note that you want to implement line breaks under the Windows operating system, we must write \ r \ n. The Mac operating system is supported by \ r.
\ ": Indicates the output double quotation mark.

 
   
  

  
    
   
Console.WriteLine("\"");
 
   
  

\ t: Tab (equivalent to pressing a TAB key) 

 
   
  

  
    
   
Console.WriteLine("张三\t李四\t王五\t赵六\t田七");
 
   
  

\b: Backspace (equivalent to BACKSPACE on the keyboard)

 
   
  

  
    
   
Console.WriteLine("张三你妈妈\b喊你回家吃饭.");
 
   
  

If you want to enter a path, that is, "\" in the string does not play the role of escaping special characters, then what to do? For example: C:\Windows\System32 solution 1: In the "\" before adding a "\", is it escaped to a common "\".

 
   
  

  
    
   
 Console.WriteLine("C:\\Windows\\System32");
 
   
  

Solution 2: Use the @ symbol

 
   
  

  
    
   
Console.WriteLine(@"C:\Windows\System32");
 
   
  

The function of the @ symbol: (1). Escapes the escaped symbol "\" in the string. (2). Output strings in the original format

 
   
  

  
    
   
Console.WriteLine(@"今天天气
  
    
   
 好晴朗");
 
   
  

Note: Other escape symbols, using the same principle and the above example escape symbol is the same, the specific use of details, in the use of the need for specific review.
