Hi all.
I have an application which will recieve ids from some other application.
Now i need to store the incoming ids to a string builder, so that i can use it for later use.For this i have created a string builder as follows
stringbuilder strIncomingEventID=new stringBuilder()
and inside the receiving method i used the below stmts
strIncomingEventID.Append(incomingmessage + Convert.ToChar(FIELD_SEP) )
now i want to retrieve each ids from it..for my manipulation...
i am not getting split properties or any thing which is useful..can any one help me in this .One more thing is that i am appending a constant FIELD_SEP to end of incoming message when i store , so that when i want to retrieve the ids ,it will be useful..is it right method.Please advise me how to get the value from the string builder
Thanks in advance
Regards
DilipRam

Can't you store the IDs in a List<string> as they come in. YOu then have a list of IDs and can use this to build your string for storage at teh end.

A StringBuilder most of the time is used to improve the performance when a series
of operations needs to be performed on textual data, that would otherwise be
stored in a string (each operation would create a new string object and copy
its data). Ultimately, when the assembly of the string is done, one normally
converts the StringBuilder to a string using the ToString() method.
Since your string operation is very simple (just a concatenation) there is no
point in using StringBuilder. And as you figured, you need a string object in
order to use the nice String methods such as Split().
[Correction: if you do this several times, there may be a performance gain
in useing StringBuilder, but in the end you have to convert back to a string].
BTW: if FIELD_SEP is a constant, there is not much point in adding it permanenty;
instead, I suggest you append it to the one string you are dealing with, when
and where you need it.

Actually, as it was done for every item that was recieved, using a StringBuilder is a good method.
As he wants to process the separate items afterwards, putting them together as a single string is of course a bad idea, regardless of the method used.

Hi
Thanks for the reply.The think here is that i will be having multiple strings coming from other application.It will be not single one or it can come any time and i need them for futher processing.So i am using string builder ,,but then how can i split these ids from the string builder.I hope i am clear abt my requirment

As I said, use ToString() to turn StringBuilder into string,
then String.Split() to split it.
But for your situation, I would not use StringBuilder at all.
Seams like you need some kind of stream or a named pipe, and perform WriteLine
and ReadLine on it.

Hi,
The Sting class has a function "Split()", which returns array of String after spliting the String on the basis of a char.

why r u making it complicated.Instead use stack or queue class and store each items one by one in it.They r fast-efficient and easy to program.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Well, containers are the solution to your problem so learn how to use them. Containers are the solution to a lot of problems.

string [] ids = strIncomingEventID.ToString().Split(...);
that should do the trick...

Yes, that would work, but it's a terrible work around.
Concatenating the values into a big string, only to split it again... Why not encrypt the string, put it in an xml document, save the xml document to disk, load it from disk, extract the data, and decrypt it, while you're at it? 
Chances are that the id:s aren't even strings at all, so a List<int> would be the best place to store them.

Good thinking man, this is even better.

You forgot to insert the xml document in that SQL database and retrieve it

Hi thanks for the reply
Actually i have an application which will recieve messages from some other application.It can happen at any time.Now i have a recieve method for this purpose..but i dont want to do any operations as soon as i recieve any id but i want it to be used later .So inorder to not loose the incoming id, i decided to used string builder so that i can append one by one the id's which are coming..but now if i want to extract it or split it,,i dont have any split method in string builder ,its only in string ..so what do i need to do.
Hope i am clear.

Then it is as I said: string [] ids = strIncomingEventID.ToString().Split(...);
You can also do this if it is easier for you:
string allids = strIncomingEventID.ToString();<br />
string [] ids = allids.Split(...);
The ToString() method of the StringBuilder class returns a variable with type string.
If you're using Visual Studio, try putting a "." after ToString() and you'll see in intellisense that Split will come up in the list.
(PS: for you info I put the "..." in Split because it is an overloaded method, view the signature on MSDN for more info on which arguments the Split method expects.)
hope this helps.

What's wrong with my first answer. As they values come in, add them to a container. A List<string> would do. Then when they are all in, you can traverse the list doing what you want with them.

If you are saying that the values come in as something like:
"a,b,c"
"d,e,f"
etc.
Then split each incoming list of IDs as it arrives and use a collection to store the individual values.

You don't store it in a single string. It's pointless to put the strings together, as you want them separate later on.
Just use a List<string>. Add each string to the list, then when you have recieved them all, you can easily access all the strings.
If the values are id:s, as the name suggests, you can use a List<int> instead. Why store them as strings, if they aren't?
