对 Excel 工作表进行排序 c# ||如何排除缺少特定单元格的行

Question

我目前正在使用 c# 开发一个 Windows 窗体应用程序，该应用程序将能够将 Pastel Partner 试算天平转换为 Pastel Evolution 兼容天平。

我正在尝试实现代码，该代码将跳过工作表中没有帐户代码的所有行（第 2 列）

请提供有关如何执行此操作的代码示例，我们将不胜感激！

如果帐户代码在第 2 列中，那么您可以检查循环中已有的空值

string[] fields = lines[i].Split(',');
if (fields[1] != "") <-- check if account code is an empty string 
{
    if (recordMatches(searchTerm , fields , positionOfSearch))
    {
    ...
