\是C#中的特殊字符(符号)。它用于转义序列(中断),例如打印新行–我们使用\ n,打印制表符–我们使用\ t 。我们必须使用双反斜杠(\\)来打印反斜杠(\) 。
如果我们在消息中写\,则会抛出错误“无法识别的转义序列” 。
例子:
Input : \\
Geeksfor\\Geeks
Output : \
Geeksfor\Geeks
Input : Clean\\Evironment
Output: Clean\Evironment
下面是上述方法的实现:
范例1:
// C# program to print backslash (\)
using System;
using System.IO;
using System.Text;
namespace geeks {
class GFG {
// Main Method
static void Main(string[] args)
{
// to print "\"
Console.WriteLine("\\");
// to print "\" between string
Console.WriteLine("Geeksfor\\Geeks");
}
}
}
输出:
\
Geeksfor\Geeks
范例2:
// C# program to print backslash (\)
using System;
using System.Text;
namespace geeks {
class GFG {
// Main Method
static void Main(string[] args)
{
// to print "\" between string
Console.WriteLine("Green\Clean");
}
}
}
错误:
Unrecognized escape sequence `\C'
范例3:
// C# program to print backslash (\)
using System;
using System.Text;
namespace geeks {
class GFG {
// Main Method
static void Main(string[] args)
{
// to print "\" between string
Console.WriteLine("Clean\\Evironment");
// to print "\"n and "\"t
Console.WriteLine("\\n\\t");
}
}
}
输出:
Clean\Evironment
\n\t
