StringReader

[Vannela]

I am using stringreader to repeat through each line of a
file ,but my string reader is clubbing 4 to 5 lines as
single line at few places, what could be the problem?

Please send me the suggestions

Thank you

Re: StringReader

Hi Vannela,

Are you shure that file lines are delimited with \r, \n, or \r\n?

Well, the problem is probably in your code. Please post a short but
complete example program which demonstrates the problem - see
http://www.pobox.com/~skeet/csharp/complete.html for what I mean by
that.

Re: StringReader

source string conatins this code:

type cb_ok from commandbutton within
w_cd_review_reg ulatory_approva l
int X=933
int Y=924
int Width=302
int Height=108
int TabOrder=40
boolean Enabled=false
boolean BringToTop=true
string Text="Approve"
boolean Default=true
int TextSize=-10
int Weight=400
string FaceName="Arial "
FontFamily FontFamily=Swis s!
FontPitch FontPitch=Varia ble!
end type

event
clicked;//*************** *************** *************** ****
*************** **
STRING l_Message[]
IF fw_Save() <> c_Success THEN
RETURN
END IF


//---------------------------------------------------------
---------
// Close the window.
//---------------------------------------------------------
---------

Close(PARENT)

//*************** ******** End of Script ************

end event

type cb_cancel from commandbutton within
w_cd_review_reg ulatory_approva l
int X=1344
int Y=924
int Width=302
int Height=108
int TabOrder=50
boolean BringToTop=true
string Text="Cancel"
boolean Cancel=true
int TextSize=-10
int Weight=400
string FaceName="Arial "
FontFamily FontFamily=Swis s!
FontPitch FontPitch=Varia ble!
end type

event
clicked;//*************** *************** *************** ****
*************** **
i_SaveOnClose = c_CloseNoSave

Close(PARENT)

//*************** ******** End of Script
*************** *************

end event

I want to get the string from the match :TYPE (followed by
some word) FROM (followed by some word) till i encounter
another such match. But my problem is in the above source
string which i have given it is matching the below whole
thing as a single line in this way that too only at few
places and with type of code ( as different input it is
working fine) what could be the problem?

I suspect your problem is that you're building up the string with just
"\n"s in instead of full carriage return / line feeds ("\r\n"). I would
also suggest using a StringBuilder instead of string concatenation.

However, you should really go through it line by line with the
debugger, and find out what lines are being *read* each time, to see
whether StringReader really is reading more than one line unexpectedly.
Does your input file perhaps contain a mixture of "\n" and "\r\n"
linebreaks? That shouldn't confuse StringReader, but it might be worht
investigating.
