正在解析 Excel 电子表格的单元格值

Question

我解析位于 A2 地址的单元格。此 returns 3 值而不是预期的 类别 1.

using System;
using System.Linq;
using DocumentFormat.OpenXml.Packaging;
using X = DocumentFormat.OpenXml.Spreadsheet;

namespace DotNetSandbox.SO
{
    public class IncorrectCellValue
    {
        public static void ParseCellValue()
        {
            using SpreadsheetDocument doc = SpreadsheetDocument.Open(@"c:\temp\test.xlsx", false);
            X.Sheet sheet = doc.WorkbookPart.Workbook.Descendants<X.Sheet>().First();
            WorksheetPart wsPart = (WorksheetPart)doc.WorkbookPart.GetPartById(sheet.Id);
            X.Cell cell = wsPart.Worksheet.Descendants<X.Cell>().First(c => c.CellReference == "A2");

            string cellValue = cell.CellValue.Text;

            Console.WriteLine(cellValue);
            Console.ReadKey();
        }
    }
}

输出：

3

目标：.NET 5
DocumentFormat.OpenXml版本：2.13.0

我做错了什么或者可能是库错误？

使用这个方法

 public static string GetCellValue(string fileName,
        string addressName, string sheetName = "")
    {
        string value = null;

        // Open the spreadsheet document for read-only access.
        using (SpreadsheetDocument document =
            SpreadsheetDocument.Open(fileName, false))
        {
            // Retrieve a reference to the workbook part.
            WorkbookPart wbPart = document.WorkbookPart;

            // Find the sheet with the supplied name, and then use that 
            // Sheet object to retrieve a reference to the first worksheet.
            var theSheets = wbPart.Workbook.Descendants<Sheet>();
            Sheet theSheet = string.IsNullOrEmpty(sheetName) ? theSheets.FirstOrDefault() : theSheets.FirstOrDefault(x => x.Name == sheetName);

            // Throw an exception if there is no sheet.
            if (theSheet == null)
            {
                throw new ArgumentException("sheetName");
            }

            // Retrieve a reference to the worksheet part.
            WorksheetPart wsPart =
                (WorksheetPart)(wbPart.GetPartById(theSheet.Id));

            // Use its Worksheet property to get a reference to the cell 
            // whose address matches the address you supplied.
            Cell theCell = wsPart.Worksheet.Descendants<Cell>().
              Where(c => c.CellReference == addressName).FirstOrDefault();

            // If the cell does not exist, return an empty string.
            if (theCell.InnerText.Length > 0)
            {
                value = theCell.InnerText;

                // If the cell represents an integer number, you are done. 
                // For dates, this code returns the serialized value that 
                // represents the date. The code handles strings and 
                // Booleans individually. For shared strings, the code 
                // looks up the corresponding value in the shared string 
                // table. For Booleans, the code converts the value into 
                // the words TRUE or FALSE.
                if (theCell.DataType != null)
                {
                    switch (theCell.DataType.Value)
                    {
                        case CellValues.SharedString:

                            // For shared strings, look up the value in the
                            // shared strings table.
                            var stringTable =
                                wbPart.GetPartsOfType<SharedStringTablePart>()
                                .FirstOrDefault();

                            // If the shared string table is missing, something 
                            // is wrong. Return the index that is in
                            // the cell. Otherwise, look up the correct text in 
                            // the table.
                            if (stringTable != null)
                            {
                                value =
                                    stringTable.SharedStringTable
                                    .ElementAt(int.Parse(value)).InnerText;
                            }
                            break;

                        case CellValues.Boolean:
                            switch (value)
                            {
                                case "0":
                                    value = "FALSE";
                                    break;
                                default:
                                    value = "TRUE";
                                    break;
                            }
                            break;
                    }
                }
            }
        }
        return value;
    }

您卡在这里：

If the cell represents an integer number, you are done. For dates, this code returns the serialized value that represents the date. The code handles strings and Booleans individually. For shared strings, the code looks up the corresponding value in the shared string table. For Booleans, the code converts the value into the words TRUE or FALSE.

我能够通过运行此代码获得类别 1：

 var cellValue = GetCellValue(@"c:\test.xlsx", "A2");

Microsoft Doc

请注意，如果您不将 sheet 名称传递给方法，我将原始方法更改为获取第一个 sheet。

什么是共享字符串： 为了优化字符串在 spreadsheet 中的使用，SpreadsheetML 将字符串的单个实例存储在 table 中，称为共享字符串 table。然后单元格按索引引用字符串，而不是将值内联存储在单元格值中。 Excel 在保存文件时总是创建共享字符串 table。
