问下这种字符串改如何分解呢750,,,,,,-750,,,742.562,,2020.033,,2020.033

750,,,,,,-750,,,742.562,,2020.033,,2020.033
分解成
750,-750,742.562,2020.033,2020.033

再如何把这个CString 转成CStringList呢

[schlafenhamster]

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
	char inStr[]=",,750,,,,,,-750,,,742.562,,2020.033,,2022.033,,,";
	char *pStrStart=inStr;
	int all=strlen(inStr);
	char *pStrEnd=pStrStart+all;
	for(int i=0; i<all; i++)
	{
		if(inStr[i]==',')
		{
			inStr[i]=0;
		}
	}
//
	int slen=0;
	while(pStrStart < pStrEnd) 
	{
		slen=strlen(pStrStart);
		if(slen)
		{
			afxDump << pStrStart<< "\n";
//			CStringArray strAr;
//			strAr.Add(pStrStart);
		}
		pStrStart += slen;// move to string end
		if(pStrStart < pStrEnd) pStrStart ++;// move to next str 
	} 
	return 0;
}
