Converting TStringlist to string with delimiter

Question

I have a list of strings stored in TStringList, i want to convert it into string seperated by commas and i use the following code

channelList: TStringList;
aCurrentChannel :=  Stringreplace(channelList.Text,Char(13)+Char(10),',',[rfReplaceAll]);

but the last character is coming as , like 1,2, is there anyway to avoid that?

Answer 1

You need to use the DelimitedText property of the TStringList class. From the online help

Use DelimitedText to get or set all the strings in the TStrings object in a single string, separated by the character specified by the Delimiter property.

Answer 2

use the DelimitedText property:

channelList.Delimiter := ',';
channelList.QuoteChar := ''; // or
channelList.QuoteChar := #0; // for higher delphi versions
aCurrentChannel := channelList.DelimitedText;

Answer 3

While you're into string lists i suggest you to cast a look at http://wiki.delphi-jedi.org/wiki/JCL_Help:IJclStringList

// var channelList: iJclStringList;
var s: string;

s := JclStringList.Add(['aaa','bbb','ccc '])
         .Split('ddd: eee', ':', False).Trim.Join(',');
