但是我用上面的代码运行后会报一堆错误，底层类好像有问题，所以改成了如下代码：文章来源地址https://www.toymoban.com/news/detail-446397.html

void CDlgStratueCal::OnBnClickedClistctrltoexc()
{
    CStringArray str11;
    for (int i = 0; i < l_list.GetItemCount(); i++)
	{
		str11.Add(l_list.GetItemText(i, 0));
		str11.Add(l_list.GetItemText(i, 1));
		str11.Add(l_list.GetItemText(i, 2));
	}
	CFileDialog fg(false, _T("*.csv"), NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
	_T("Excel CSV File(*.csv)|*.csv|Text File(*.txt)|*.txt|All File(*.*)|*.*||"), NULL);
	if (fg.DoModal() == IDOK)
	{
		CString filename = fg.GetPathName();
		CStdioFile file(filename, CFile::modeCreate | CFile::modeWrite);
		CString str = _T("序号,地层厚度,实际厚度\n");
		file.WriteString(str);
		for (int i = 0; i < str11.GetSize() - 1;)
		{
			if (i == 0)
			{
				str = str11.GetAt(i) + _T(",");
				str += str11.GetAt(++i) + _T(",");
				str += str11.GetAt(++i) + _T("\n");
			}
			else
			{
				str = str11.GetAt(++i) + _T(",");
				str += str11.GetAt(++i) + _T(",");
				str += str11.GetAt(++i) + _T("\n");
			}
			file.WriteString(str);
		}
		file.Close();
	}
