我正在使用Open XML SDK创建Excel文件，并希望使用Open XML阅读它。当我想要读取它时，我会在这一行代码处出现错误：
它使用以下代码创建一个文本和数字值：
SharedStringTablePart sstpart = workbookPart.GetPartsOfType<SharedStringTablePart>().First();它返回null。
如果我打开Excel文件并重新保存，它会创建共享字符串表并运行。
从Excel中进行读取。
#region OpenFile
public void OpenFile(string directory)
{
try
{
fs = new FileStream(directory, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
doc = SpreadsheetDocument.Open(fs, false);
}
catch (FileNotFoundException ex)
{
string exception = string.Format("Doya bulunamadı{0}", directory);
throw new ApplicationException(exception);
}
}
#endregion
#region GetWorkSheet
public void AssignWorkSheet(int sheetID)
{
if (fs == null || doc == null)
throw new ApplicationException("Dosya açılamadı");
WorkbookPart workbookPart = doc.WorkbookPart;
SharedStringTablePart sstpart = workbookPart.GetPartsOfType<SharedStringTablePart>().First();
sst = sstpart.SharedStringTable;
var workbook = workbookPart.Workbook;
var sheets = workbook.Descendants<Sheet>();
var sheetINVOICE = sheets.ElementAt(sheetID);

这个程序可以写入一些文本和数字值：
