c# 反斜杠 双斜杠

C＃打印反斜杠(\) (C# printing a backslash (\))

In C#, \ is a special character (sign) – that is used for escape sequences like to print a new line – we use \n, to print a tab – we use \t etc.

在C＃中， \是一个特殊字符(符号)–用于转义序列，例如打印新行–我们使用\ n ，打印制表符–我们使用\ t等。

In this case, if we write \ within the message – it will throw an error "Unrecognized escape sequence".

在这种情况下，如果我们在消息中写\ ，则会抛出错误“无法识别的转义序列” 。

To print a backslash (\), we have to use a double backslash (\\).

要打印反斜杠( \ )，我们必须使用双反斜杠( \\ )。

C＃代码打印反斜杠 (C# code to print a backslash)

In the below example – we are printing backslash, \n, \t etc

在下面的示例中–我们正在打印反斜杠， \ n ， \ t等

// C# program to print backslash (\)
using System;
using System.IO;
using System.Text;

namespace IncludeHelp
{
    class Test
    {
        // Main Method 
        static void Main(string[] args)
        {
            // printing "\" 
            Console.WriteLine("\\");

            // printing between string "\"
            Console.WriteLine("Hello\\World");

            // printing "\"n and "\"t
            Console.WriteLine("\\n\\t");

            //hit ENTER to exit the program
            Console.ReadLine();
        }
    }
}
