从excel文件中打开xml读取

我想在我的项目中实现openXml sdk 2.5。我在此链接中进行了所有操作

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Spreadsheet;
using System.IO.Packaging;


static void Main(string[] args)
        {

            String fileName = @"C:\OPENXML\BigData.xlsx";
            // Comment one of the following lines to test the method separately.
            ReadExcelFileDOM(fileName);    // DOM
            //ReadExcelFileSAX(fileName);    // SAX
        }

        // The DOM approach.
        // Note that the code below works only for cells that contain numeric values.
        // 
        static void ReadExcelFileDOM(string fileName)
        {
            using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(fileName, false))
            {
                WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
                WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
                SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();
                string text;

                int rowCount= sheetData.Elements<Row>().Count();

                foreach (Row r in sheetData.Elements<Row>())
                {
                    foreach (Cell c in r.Elements<Cell>())
                    {
                        text = c.CellValue.Text;
                        Console.Write(text + " ");
                    }
                }
                Console.WriteLine();
                Console.ReadKey();
            }
        }

但是我什么也没有。它尚未进入循环。注意：我还在计算机上设置了openXml sdk 2.5

我发现下面的代码适用于数字值。对于字符串值，它写0 1 2 …

 private static void Main(string[] args)
            {
                var filePath = @"C:/OPENXML/BigData.xlsx";
                using (var document = SpreadsheetDocument.Open(filePath, false))
                {
                    var workbookPart = document.WorkbookPart;
                    var workbook = workbookPart.Workbook;

                    var sheets = workbook.Descendants<Sheet>();
                    foreach (var sheet in sheets)
                    {
                        var worksheetPart = (WorksheetPart)workbookPart.GetPartById(sheet.Id);
                        var sharedStringPart = workbookPart.SharedStringTablePart;
                        //var values = sharedStringPart.SharedStringTable.Elements<SharedStringItem>().ToArray();

                        string text;
                        var rows = worksheetPart.Worksheet.Descendants<Row>();
                        foreach (var row in rows)
                        {
                            Console.WriteLine();
                            int count = row.Elements<Cell>().Count();

                            foreach (Cell c in row.Elements<Cell>())
                            {

                                text = c.CellValue.InnerText;

                                Console.Write(text + " ");

                            }
                        }
                    }
                }

                Console.ReadLine();
            }

您的方法对我来说似乎行得通-因为它确实“进入了循环”。不过，您也可以尝试以下操作：

void Main()
{
    string fileName = @"c:\path\to\my\file.xlsx";

    using (FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
    {
        using (SpreadsheetDocument doc = SpreadsheetDocument.Open(fs, false))
        {
            WorkbookPart workbookPart = doc.WorkbookPart;
            SharedStringTablePart sstpart = workbookPart.GetPartsOfType<SharedStringTablePart>().First();
            SharedStringTable sst = sstpart.SharedStringTable;

            WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
            Worksheet sheet = worksheetPart.Worksheet;

            var cells = sheet.Descendants<Cell>();
            var rows = sheet.Descendants<Row>();

            Console.WriteLine("Row count = {0}", rows.LongCount());
            Console.WriteLine("Cell count = {0}", cells.LongCount());

            // One way: go through each cell in the sheet
            foreach (Cell cell in cells)
            {
                if ((cell.DataType != null) && (cell.DataType == CellValues.SharedString))
                {
                    int ssid = int.Parse(cell.CellValue.Text);
                    string str = sst.ChildElements[ssid].InnerText;
                    Console.WriteLine("Shared string {0}: {1}", ssid, str);
                }
                else if (cell.CellValue != null)
                {
                    Console.WriteLine("Cell contents: {0}", cell.CellValue.Text);
                }
             }

             // Or... via each row
             foreach (Row row in rows)
             {
                 foreach (Cell c in row.Elements<Cell>())
                 {
                     if ((c.DataType != null) && (c.DataType ==           CellValues.SharedString))
                     {
                         int ssid = int.Parse(c.CellValue.Text);
                         string str = sst.ChildElements[ssid].InnerText;
                         Console.WriteLine("Shared string {0}: {1}", ssid, str);
                     }
                     else if (c.CellValue != null)
                     {
                         Console.WriteLine("Cell contents: {0}", c.CellValue.Text);
                     }
                 }
             }
         }
     }
 }

我使用文件流方法来打开工作簿，因为它允许您使用共享访问权限来打开它-
这样您就可以同时在Excel中打开工作簿。如果工作簿在其他位置打开，则Spreadsheet.Open（…方法将不起作用。

也许这就是为什么您的代码无法正常工作的原因。

还要注意，在适当的地方使用SharedStringTable来获取单元格文本。

编辑2018-07-11：

由于该帖子仍在获得投票，我还应该指出，在许多情况下，使用ClosedXML操作/阅读/编辑工作簿可能会容易得多。这些文档示例非常易于使用，根据我的有限经验，编码非常简单。请注意，它尚未（尚未）实现可能是或不是问题的所有Excel函数（例如INDEX和MATCH）。[不是我想无论如何都要尝试处理OpenXML中的INDEX和MATCH。]
