將后的"http://quote.yahoo.com/d/quotes.csv?s="+symbol+"&f=sl1d1t1c1ohgvj1pp2owern&e=.csv"; 這一串變為字符串.
如果不加@,如果字符串里有轉義符的話,可能會出錯.

如果没有@符号，就必须用转换符，看c的转换符Top

@-quoted string literals start with @ and are enclosed in double quotation marks. For example:
@"good morning" // a string literal
The advantage of @-quoting is that escape sequences are not processed, which makes it easy to write, for example, a fully qualified file name:
@"c:\Docs\Source\a.txt" // rather than "c:\\Docs\\Source\\a.txt"
To include a double quotation mark in an @-quoted string, double it:
@"""Ahoy!"" cried the captain." // "Ahoy!" cried the captain.
