Vista - @"string"

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

What does the @ do?


thanks!

Do you mean for 'parameters' in sql statements?

Can you post an example of what you see?

Hello Mike Gleason jr Couturier,
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.
-------------------------------------------------------------

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!

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.

without @: var str="e:\\folder1\\folder2\\folder3\\file"

with @: var str=@"e:\folder1\folder2\folder3\file"
