special character replacement
-
Normally, you don't need to:
Console.WriteLine("\\");
will output
\. You have to do extra work to switch the escaping functionality off (using @ before the string):Console.WriteLine(@"\\");
will output
\\. If you are still having problems, please post extra code so we can see what is going on better.ragnaroknrol The Internet is For Porn[^]

The code I added does work, I checked it, and it is part of the language specification! If you want to output \ you need to use "\\" or @"\" If you want to output \\ you need to use "\\\\" or @"\\" The @ character switches the escaping off. If you are still having problems, I suggest you post more of your code, something else might be happening!

hi how can i replace "\\" with "\". because i am using, String.Replace("\\","\"); but it does not work. thanx
-
Is that your actual code? working example...
string s = @"some\\text";
s = s.Replace(@"\\", @"\");
//s should now = "some\text";Life goes very fast. Tomorrow, today is already yesterday.
Actually i am using xml file. In my xml file contains following text: \u092A\u094B\u0937\u093E\u0939\u093E\u0930 and i want to convert in correspponding letter through httpUtility.htmlEncode(). when i put above code in htmlEncode function, it works properly. when i retrieve this in C# as string it shows like: \\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930. so this is not convert. please guide me.

Why do you need to?

If you are simply looking at the value in the debugger, then those extra back-slashes aren't really there, don't worry about them.

i WANT TO RETRIEVE EQUIVALENT VALUE OF THE GIVEN STRING. THE ABOVE CODE VALUE IN SEE IN HINDI IS "POSHAHAR".
OW! My eyes!

OW! My eyes!
And ears...... It turns out the code I posted demonstrating the difference between
Console.WriteLine("\\");
Console.WriteLine(@"\\");doesn't work. There goes ~10 years of .net experience perhaps I should go back to asking people to switch it off and on again for a living :-)

that is not informative at all. if you want a good answer, then provide quality information to begin with. Don't say "it does not work", specify what kind of problem there is (compilation error, run-time error, ...) and be specific (error number, exception message, line number, etc). :)

this is my string: \u092A\u094B\u0937\u093E\u0939\u093E\u0930i used this code:string unicodeString = HttpUtility.HtmlEncode("\u092A\u094B\u0937\u093E\u0939\u093E\u0930");
MessageBox.Show(unicodeString);it gives me answer correct as "POSHAHAR" IN HINDI FONT. BUT if we use above text as string it gives
string unicodeString = HttpUtility.HtmlEncode(above_code);
MessageBox.Show(unicodeString);the string takes value in this form: "\\u092A\\u094B\\u0937\\u093E\\u0939\\u093E\\u0930";
so, it can't work. then my problem is , how am i replace "\\" instead of "\".

It is not as you said: in C# each string is unicode and something like "\u092A" is an escape sequence that mean "the unicode character with the code 0x092A. In other words, it is not a sequence of characters, but a single one.

Hi, much better now, I understand you happen to have strings that hold Unicode characters in their \u format (as accepted by the C# compiler), and need them to be interpreted. I wasn't able to locate a .NET class that really supports this, so the best I could come up with is:
static string DecodeUnicode(string s) { StringBuilder sb=new StringBuilder(); while (s.Length!=0) { sb.Append((char)int.Parse(s.Substring(2, 4), NumberStyles.HexNumber)); s=s.Substring(6); } return sb.ToString(); }which only accepts strings that consist of groups of six characters (a backslash, a 'u', and 4 hex digits); you may choose to add checks and error handling. It works for your example.
string s="\\\\u092A\\\\u094B\\\\u0937\\\\u093E\\\\u0939\\\\u093E\\\\u0930"; log(s); s=DecodeUnicode(s); log(s);FWIW: I think you got yourself into trouble; most of the time, you should simply avoid having to do this, and have the compiler translate those \uXXXX sequences into single characters! PS: I'm not sure what HttpUtility.HtmlEncode is doing for you. :)
