如何在 OpenXML 中计算每个工作表的行数

Question

我从Interop 库切换到OpenXML，因为我需要读取大型Excel 文件。在此之前我可以使用：

worksheet.UsedRange.Rows.Count

获取工作表上包含数据的行数。我用这些信息制作了一个进度条。在 OpenXML 中，我不知道如何获得有关工作表的相同信息。我现在拥有的是这段代码：

 using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(path, false))
{
    WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
    WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
    SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();
    int row_count = 0, col_count;
    // here I would like to get the info about the number of rows
    foreach (Row r in sheetData.Elements<Row>())
    {
        col_count = 0;
        if (row_count > 10)
        {
            foreach (Cell c in r.Elements<Cell>())
            {
                // do some stuff  
                // update progressbar  
            }
        }
        row_count++;
    }
}

没那么难（当你使用LINQ），

 using (SpreadsheetDocument myDoc = SpreadsheetDocument.Open("PATH", true))
 {
   //Get workbookpart
   WorkbookPart workbookPart = myDoc.WorkbookPart;

   //then access to the worksheet part
   IEnumerable<WorksheetPart> worksheetPart = workbookPart.WorksheetParts;

   foreach (WorksheetPart WSP in worksheetPart)
   {
      //find sheet data
      IEnumerable<SheetData> sheetData = WSP.Worksheet.Elements<SheetData>();       
      // Iterate through every sheet inside Excel sheet
      foreach (SheetData SD in sheetData)
      {
           IEnumerable<Row> row = SD.Elements<Row>(); // Get the row IEnumerator
           Console.WriteLine(row.Count()); // Will give you the count of rows
      }
}

使用Linq 编辑，现在很简单。
