4. To initialize string as null
Initialize string to null (escape sequence).
Practical Implementation:
using System;
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
/*Initializing string to null with escape sequence*/
string str = "\0";
Console.WriteLine("null by escape sequence = " + str);
/*other ways to initialize string to null*/
string a = null;
Console.WriteLine("null by string variable a = " + a);
}string str = "\0";
Console.WriteLine("null by escape sequence = " + str);
/*other ways to initialize string to null*/
string a = null;
Console.WriteLine("null by string variable a = " + a);
}
}
5. To print backspace
This
escape sequence ( \b ) is used to remove one character from your string
i.e, preceding to its left wherever it is mentioned.
Practical Implementation:
using System;
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
/*To print backspace*/
Console.WriteLine("backspace = Imagination\bhunt");
Console.WriteLine("backspace = Imagination\bhunt");
}
}
}
}
}
In our output 'n' is removed as ( \b ) is used just after "Imagination". Implies, that character i.e, preceding to left of ( \b ) is deleted.
6. To print Form feed
If
you were programming for a 1980-style printer, it would eject the paper
and start a new page. You are virtually certain to never need it. I
have mentioned just in case to know what form feed escape sequence are.
Practical Implementation:
using System;
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
namespace AspnetSolutions
{
class stringEscapeSequences
{
public static void Main()
{
/*To print formfeed*/
Console.WriteLine("formfeed = Imagination\fhunt");
Console.WriteLine("formfeed = Imagination\fhunt");
}
}
}
}
}
