@"string"

[Mike Gleason jr Couturier]

Why do I see a @ preceding strings in code examples?

What does the @ do?


thanks!

Re: @"string&q uot;

Do you mean for 'parameters' in sql statements?

Can you post an example of what you see?

I believe it is a c# sytax that prevents the compiler otherwise interpreting
certain characters as escape codes.

for example
-------------------------------------------------------------
string SomeString = "\n"; //This produces an enter keystroke
string OtherString = @"\n"; //This produces a string containing the backslash
and 'n' characters.
-------------------------------------------------------------

Correct and in addition a string preceded with @ can split across lines:-

string someSQL = @"
SELECT a.Field1, a.Field2
FROM ATable a
INNER JOIN BTable b ON b.ID = a.ID
WHERE b.Field3 = 15"

The down side is that " need to be duplicated as "" e.g.:-

string someXML = @"<root thing=""x"" />"

Ok thanks guys...

I was seeing the @ when declaring connection strings in books... (web
projetcs, web.config)

Thanks!

Re: @&quot;string&q uot;

You should also read up on
"SQL Injections"... just google it up

It will give you good examples of why the @ is used as a parameter.

thanks!

with this symbol you could go without escape chars, for example

without @: var str="e:\\folder 1\\folder2\\fol der3\\file"

with @: var str=@"e:\folder 1\folder2\folde r3\file"
