如何从一个带有分隔符的字符串里读出每个子串??

[zhaoxinghan]

比如有一个字符串是"123,345,345,1234",怎么样分别得到"123","345","1234"呢?希望得到简单的方法实现.

哈哈，我刚好写完的代码中用到了这个算法要简单的吧？

void __fastcall TForm1::Button1Click(TObject *Sender)
{
AnsiString sourceStr="123,345,345,1234";

String value;
int index=0;
int pos=sourceStr.Pos(",");
while (pos>0)
{
value=sourceStr.SubString(1,pos-1);
sourceStr.Delete(1,pos);
pos=sourceStr.Pos(",");
index++;
ShowMessage(value);
}
value=sourceStr;
ShowMessage(value);
delete ss;
}

这个是我的写法你照着改一下就是了

[Gamma_Beam]

AnsiString AStr=SourceString;
TStringList* sRet=new TStringList();
int iPos=AStr.Pos(",");
while(iPos>0 )
{
sRet->Add(AStr.SubString(1,iPos-1));
AStr.Delete(1,iPos);
iPos=AStr.Pos(",");
}
if(!AStr.IsEmpty())
sRet->Add(AStr);

TStrings *strs =NULL;
strs =new ...
if(strs)
strs->Delimiter =',';
strs->DelimitedText ="123,345,345,1234";
if(strs->Count >0)
for(int ii=0; ii <strs->Count; ++ii)
strs->Strings[ii]...
...

delete strs

其实我就是想要kyodan的那种方法,上边的两种我以前都用过.
