Question

我正在从Excel工作表中检索单元格，这是我得到的输出。

Cell A2 has value 113,295
Cell B2 has value 540
Cell C2 has value 41,044
Cell A3 has value 192,653
Cell B3 has value 510
Cell C3 has value 41,037

代码：

using (ExcelPackage package = new ExcelPackage(existingFile))
{
    ExcelWorksheet sheet = package.Workbook.Worksheets[1];

    //Select all cells in column d between 9990 and 10000
    var query1 = (from cell in sheet.Cells["A2:C2"] select cell);

    int count = 0;
    string[] s = null;

    foreach (var cell in query1)
        Console.WriteLine("Cell {0} has value {1:N0}", cell.Address, cell.Value);
}

我的问题是我想创建一个包含成员a，b和c的类，我想要一个List＆lt;＆gt;持有这些物品的集合。

目前，它正在迭代，但我不知道for循环中哪个单元格是A，B或C.

您可以编写一个分区方法，并为其指定行的长度......在您的情况下为3

IEnumerable<List<T>> Partition<T>(IEnumerable<T> col, int partitionSize) {
 if (col.Count() == 0) {
  return new List<List<T>>();
 } else {
  var l = new List<List<T>>();
  l.Add(col.Take(partitionSize).ToList());
  return l.Concat(Partition(col.Skip(partitionSize), partitionSize));
 }
}

class TheClass {
 public int A, B, C;
}

return Partition(sheet.Cells["A2:C2"], 3)
         .Select(cells => new TheClass { 
           A = int.Parse(cells[0].Value),
           B = int.Parse(cells[1].Value),
           C = int.Parse(cells[2].Value)
         });

我希望这会有所帮助
