Question

using ClosedXML.Excel;

class XLSXWriter : BExporter
    {
        private readonly string _fName;

        public XLSXWriter(string fileName)
        {
            _fName = fileName;
        }

        public override void Export(IEnumerable<AnimalData> animals)
        {
            var workBook = new XLWorkbook(); <---Throws an exception

            var workSheet = workBook.Worksheets.Add("MySheet");

            workSheet.Cell("A1").Value = "Hello World";            

            FileStream fs = new FileStream(_fName, FileMode.Create);
            workBook.SaveAs(fs);
            fs.Close();          
        }
    }

只是尝试这个库ClosedXML.dll，它抛出一个异常无法弄清楚可能是什么问题。我从_fName获得了savefiledialog。任何人的想法？

Answer 1

思想会删除这篇文章，但未来可能会帮助某人......我所要做的就是再引用一个DLL DocumentFormat.OpenXml.dll。现在完美运作！

Answer 2

更新closedXML库后，我修复了相同的错误。换句话说，如果ClosedXML和OpenXML是更新包，则不会发生此错误。

'ClosedXML.Excel.XLWorkbook'的类型初始化程序引发了异常
