[ccbbcc]

代码：

using System;

using System.IO;

using OfficeOpenXml;



class Program

{

    static void Main()

    {

        // 定义文件路径

        string filePath = @"d:\File.xlsx";



        // 创建 Excel 文件并写入数据

        using (var package = new ExcelPackage())

        {

            // 添加一个工作表

            var worksheet = package.Workbook.Worksheets.Add("Sheet1");



            // 写入数据

            worksheet.Cells[1, 1].Value = "Hello, Excel!";

            worksheet.Cells[2, 1].Value = "This is a test.";



            // 保存文件

            FileInfo fileInfo = new FileInfo(filePath);

            package.SaveAs(fileInfo);

        }



        Console.WriteLine("Data has been written to Excel without showing a save dialog.");

    }

}

运行错误

请问专家，如何解决？谢谢
