C# Newbie

I am simply trying to put a connection string in a constant so i don't have to write the connection string out 4-6 times. But it is not working!! How do I fix it?? It is ASP.Net, but it is a C# language problem that is why I posted it here.

Compiler Error Message: CS1009: Unrecognized escape sequence

That is all correct Except where you have MapPath("blah

in c# and many other languages

char "\" in a string is a constant representing many "unrepresentable" characters such as new line

eg.
if you have
string aString = "hello\nworld";

when you display aString, you will see

hello
world

now to your problem.. there are two ways to overcome this.. one is for eveery \ replace it with \\ as \\ represents \

2nd way is to use @ sign

so

Server.MapPath(@"\nigorr\db\test\miniPassport.mdb")

@ sign ignors any \ being interpreted as a constant (escape sequence).

so
string aString @"hello\nworld";
will display

hello\nworld

hope this help

Thanks for that, glad you could clear that up for me.
