I want to use \ in a string, like
string str="abc\xyz";
But this is giving me error.
I have also tried
string str="abc\\xyz";
But still it isnt working. Can anyone help me out?

You can either escape the character, like so:
string str="abc\\xyz";
or use a verbatim string literal like so:
string str=@"abc\xyz";
So your second example should work.
See here for more information.

FYI, the latter is called a
verbatim string literal.Dave Van den Eynde
Got an upvote on a 9 year old answer. I love this place.
Well, the latter ("abc\\xyz") will certainly result in a backslash in the string - or you could use a verbatim string literal:
string str = @"abc\xyz";
Note that if you use the debugger to look at your strings, it will often (always?) "escape" them for you, so you'd see "abc\\xyz". This can cause a fair amount of confusion. Either look at the characters individually, or print the string to the console.
You haven't said in what way it "isn't working" - could you give more details? If it's just the debugger output, then the above may be all you're looking for - but otherwise you should tell us what you're seeing vs what you expected to see.
Have a look at my article about strings for more information about strings in general, escaping, the debugger etc.

Yes. While debugging i see abc\\xyz when i used @"abc\xyz".

And due to this i am unable to do anything further in my code.

@Brigadier: But that's the correct data. Why does the debugger showing you the right data but as a verbatim string literal make you "unable to do anything further in [your] code"? What's actually stopping you from continuing? What unexpected results are you getting apart from seeing the string in verbatim string literal format?

I am extracting the substring after \ from abc\xyz i.e.i want xyz. But by writing string str=@"abc\xyz" i am getting \xyz.
Jon Skeet
@Brigadier: Then your code to extract the substring is broken. I suspect you're missing a "+1".

string str="abc\\xyz";
Normally, this should work. An alternative is:
string str = @"abc\xyz";
Comments
public class Program
{
static void Main(string[] args)
{
string str = "abc\\xyz";
Console.WriteLine(str);
}
}
This works fine. It prints abc\xyz.

You can do it like this
string str = @"abc\xyz";
Comments
string str = @"abc\xyz";
Comments
You can do this:
string str = @"abc\xyz";
That tells says that the slash is significant and not an escape character.
Comments
You'll need to prefix the string with the '@' symbol to stop the compiler trying to treat it as an escape sequence. So string str = @"abc\xyz"; should work.
string str = "abc\\xyz"- i.e. just two back slashes? Having three gives "unrecognised escape sequence"
