Lan Unity Development Basics using strings

Content in this section: Using Strings: string concatenation, escape characters

One, string concatenation: string can use + or + = string splicing!!

Second, transfer character--example \ n (for carriage return, line break)

Transfer character

Escape _ Escape Meaning

\n_ indicates a newline or carriage return

\t_ represents a tab character

\ "_ means double quotation marks

\ ' _ denotes single quotation marks

\\_ = backslash

Adding the @ symbol in front of the string invalidates the escape character of the string!

After a string literal is invalidated, we need to use two double quotation marks to print the double quotation marks

            The // string cannot be mathematically operated using subtraction, but you can use the operator symbol!
            // string concatenation
            stringname=" Lao Wang " ;
            stringsay =" Hello " ;
            // You can use the plus sign to stitch strings in a string
say = say + name;//" Hello Tokugawa Ieyasu "
            //+ + can also be used
            //say + = name;
            //console.writeline (say);

            // Escape _ escape meaning
            //\n_ indicates a newline or carriage return
            //\t_ represents a tab character
            stringstr ="\ tLi Bai\ nbefore the bed was bright moonlight,\ nsuspicion is ground frost.  ";
            Console. WriteLine (str);

            //\ "_ means double quotation marks
            //\ ' _ denotes single quotation marks
            //\\_ = backslash
             After a string literal is invalidated, we need to use two double quotation marks to print the double quotes

            Console. WriteLine (s);
            stringSS = " use in strings \ n means line break! ";

            // How to Output the original \ n
            //1. in the \ n before adding a \
SS = " use in strings \\n means line break! ";
            //2. in front of the string, add @ symbol, it invalidates the escape character of the string!
SS =@ "Use \ n in a string to represent a newline!" ";
            Console. WriteLine (ss);
