哪位大侠帮我改改代码吧

[chaylenliu]

代码写的太烂了，内存都满了，求求哪位大侠帮我改改吧
就是下面的代码，读“1,2,0,23,Ba”这个数据放在不同的变量里，先谢过了
===========================================================================
TUint16 table(0);
TInt n(0);
TInt aId(0);
TInt aPrice(0);
TBuf<30> aName;
aName.Zero();


TBuf16 <50> iDes;
iDes = _L("1,2,0,23,Ba,");

TLex lex(iDes);

TLex iLexs(_L(""));

//HBufC16* copy;
TChar ch(',');
TInt iDouNum(0);
TBuf16 <50> result;
result.Zero();

while(ETrue)
{
if(lex.Peek() == ch )
{
iDouNum++;
lex.Inc();
lex.Mark();
result.Zero();
}
else
{
if(iDouNum==0)
{
lex.Mark();
}
else
{
TPtrC item = lex.MarkedToken();
result.Append(item);

if(lex.Peek() == 0)
{
break;
}
else
{
lex.Inc();
lex.Mark();
}
}
}
iLexs = result;

if (iDouNum <2 )
{
switch(iDouNum)
{
case 0:
iLex.Val(table);
break;
case 1:
iLexs.Val(n);
break;
default:
break;
}
}
else if (iDouNum > 1)
{
switch(iDouNum%3)
{
case 2:
iLexs.Val(aId);
break;
case 0:
iLexs.Val(aPrice);
break;
case 1:
aName.Zero();
aName.Append(result);
break;
default:
break;
}
}
}

按“，”分割就可以了，也可一看看VC里面scanf得用法

草拟代码，供参考：

TInt len = 0;
TInt nDouNum = 0;
const TDesC& data = ...;  // 
while (ETrue)
{
  TPtrC ptr = data.Mid(len);
  TInt pos = ptr.Find(',');
  if (pos == KErrNotFound) break;
  if (nDouNum == 0)
  {
  // parse as number
  TInt num0;
  TLex lex(ptr.Mid(0, pos));
  if (lex.Val(num0) == KErrNone)
    {
    // do with num0
    } 
  }
  else if (nDouNum == 1)
  {
  ...
  }

  len += pos; //
  ++len; // skip ,
  ++ nDouNum; // 
}
