as i already said i had provide the complete info at http://www.codeproject.com/Answers/195111/input-string-is-not-in-correct-format-error-when-u.aspx
Actually the columns in the datatable is string type..my requirement is when user clicks on the header sorting should
happen ...and the datatable(3 columns) contains values in 2nd,3rd columns were like..
2%,5%,6% etc...and in 1st column 1,2,3..
so wat i tried is im creating one more column of decimal type dynamically when user clicks on column..from the values in the column(after removing % from the string values and converting to decimal)...
correct me if im wrong..

You should not be using a string-type column at all; if the data is numeric, use a numeric-type column, that will give you numeric sorting instead of alphabetical sorting (i.e. 9 - 10 - 11 and not 10 - 11 - 9). There is a difference between what a cell value means (a number, a percentage, whatever) and how it looks (with or without thousands separator, with or without a % sign, etc), that is what cell format properties and events are taking care of. I think I already told you all that.

i need to get the character when the unicode is given.
for example :
i get the unicode values as a string -> "\U0061" so then i need to get the character for this unicode value.
i know that i can use "char c = '\U0061' but unfortunately i get the Unicode value as a string, so what i need is to get the character by that string .
anyone got an idea to do this.
thanx in advance.

I only know three ways to do something of that kind.
string s="\U0061";
char c0=s[0];
char c1='\u0061';
char c2=(char)0x0061;

?????????????????????
string s only holds one character. the whole backslash-u-fourdigirs thing is C#'s way to specify a single character by its Unicode character number.

thanx Luc, i had made a mistake , i had used "U" instead of "u" , when i use "U" it gives me the unrecognized escape sequence . but with "u" it works fine thank you.

You can parse it as int (the 0061 part) and then cast to char.
|
|
|
|
|
could you please guide me on that. thanx.
|

First search for occurrences of \\U[0-9]+ (that's a regex, the backslash is escaped and you may have to doubly-escape it)
Then replace it with (char)int.Parse(match.Value.Split('U')[1]) (though I would refactor that)

You have a problem. The four digits after the \u are HEX not decimal. So int.Parse won't cut it.
Cheers,

OP didn't say so, so how do you know?

Because that's the way \unnnn works. Big brother to the \xnn convention for single byte characters.
Borrowing a couple of sentences from the Java Language Specification, section 3.2:
A Unicode escape of the form \uxxxx, where xxxx is a hexadecimal value, represents the Unicode character whose encoding is xxxx. This translation step allows any program to be expressed using only ASCII characters.

\unnnn doesn't work any particular way, it's just a string..
Of course it works that way in Java and C# and no doubt some other places as well, but there's no guarantee that it always does and OP should have specified it

Why does that matter? It's not about the string "\Uanything" (ie a string containing the actual character), but about a string containing "\\Uanything" that has to be converted the the first form. Anything could still be in any form - nowhere did he say that it originates from C# sourcecode.

I didn't have a problem understanding what OP wanted to do. Luc didn't have a problem. Richard didn't have a problem. jschell didn't have a problem. OP didn't have a problem understanding Luc's answers.

Actually they all had problems understanding what he meant.
Luc's first answer doesn't answer the question, Richard's answer doesn't the question, Luc's first version of his second answer parsed it as decimal aswell IIRC and jschell just noted a problem with what the OP is trying to do.

F*** you.
It was a legitimate discussion.
You are the troll here, not me.

Precisely, because I did not think the question was clear, and it had already received enough suggestions from other people. BTW I was not confused about the hex/decimal question; as you rightly pointed out the OP did not specify what the number format was.

Wrong.
I edited to improve the error checking, basically I added s==null || s.Length!=6 || s[0]!='\\' || s[1]!='U' to the if(...) throw statement.
Now stop this silly dispute, none of us know exactly what the OP intended, as is often the case, unfortunately. That is why I ended up providing two different answers, assuming one of them would hit the actual question.

And let me remind you, you are wrong.
The OP did not specify that the number had to be in HEX, therefore it was not clear.
