String Literal
A String literal can take three formats, where ccc is a string with no newlines, and mmm is a string including newline characters:
Without Newlines:
"<ccc>": single line string. To have a ‘ inside it, write it twice, e.g. ‘bob’’s office’"<ccc>": single line string. To have a “ inside it, write it twice e.g. “bob said ““hello world”””
With Newlines:
@"<mmm>": multiline string. To have a “ inside it, write it twice e.g. “bob said ““hello world”””
Remarks
Single line strings can be continued on the next line if and only if the last non-blank character of the line is a + sign. In this case, the string contains the characters up to the +, excluding the +, and the characters starting in the first column onwards of the continuation line.
Examples
"hello world"
‘this is a string +
continued on the next line’ : this is equal to ‘this is a string continued of the next line’
@"I want to have newlines
in my string, so I use a multiline string!!!"
