我有一个加载了 csv 文件的 gridview。我需要遍历时间和日期列，因此当用户选择行时，它将在不同行中找到下一个日期和时间。所以，那个老板可以看到那个人工作了多少小时。我需要从“A02 - 后门（比如登录或打卡）中找到总小时数，这个循环需要在 10 小时的时间跨度后找到最后一扇门。请帮忙。

单击您的行后，检索您的 DateTime 值。然后遍历其余行（或 LINQ 查询）以查找具有您要查找的“下一个”日期时间值的下一行。

编辑：在您的 csvGridView_CellClick 方法中，您检索被单击的单元格的行索引。如果您需要在 10 小时后找到该人的下一次匹配项，请从当前行获取 startDate，您已经在执行此操作。完成后，调用一个名为“LocateNextEntryForPersonAtXDateTime(string personName, string targetDateTime)”的新方法，如下所示：

private int LocateNextEntryForPersonAtXDateTime(string personName, DateTime targetDateTime)
{
  for (int i = 1; i <= csvGridView.Rows.Count; i++)
  {
     if (csvGridView.Rows[i][0].Value.ToString().ToLower() == personName.ToLower()
       && Convert.ToDateTime(csvGridView.Cells[i][1].Value) >= targetDateTime)
         return i; // this is the row for the next entry when the person leaves
  }

  return -1; // not found
}
