special character replacement

[varsh12]

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?

[PIEBALDconsult]

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".

[PIEBALDconsult]

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\u0930 i 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. :)
