使用Epplus以及Excel将模板导出excel

public static void TemplateWrite<T>(List<T> datas, int startRow = 2, string targetPath = @"D:\导出excel测试.xlsx", string templatePath = @"D:\github\Demo\NetCoreDemo\src\ExcelDemo\Template\template.xlsx")
        {
            var stream = FileToStream(templatePath);

            using (ExcelPackage package = new OfficeOpenXml.ExcelPackage(stream))
            {
                ExcelWorksheet worksheet = package.Workbook.Worksheets[1];

                startRow = 3;
                Type myType = typeof(T);

                var pros = myType.GetProperties();

                foreach (var data in datas)
                {
                    worksheet.Cells.AutoFitColumns();//自适应宽度

                    var column = 1;
                    foreach (var item in pros)
                    {
                        //遍历赋值：前提是要顺序一致。
                        var value = item.GetValue(data, null);
                        worksheet.Cells[startRow, column].Value = value;
                        column++;
                    }

                    startRow++;
                }
                FileInfo fs = new FileInfo(targetPath);
                package.SaveAs(fs);
            }
        }

  public class Students
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public int ClassNum { get; set; }
        public decimal Math { get; set; }
        public decimal Lang { get; set; }
        public string dec { get; set; }
    }

 static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");

            List<Students> students = new List<Students>();
            students.Add(new Students() { Name = "张三", Age = 5, ClassNum = 6, Lang = 90, Math = 89,dec= "dddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd" });
            students.Add(new Students() { Name = "李四", Age = 8, ClassNum = 5, Lang = 70, Math = 99, dec = "dddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd" });

            EpplusExcelHelper.TestTemplateWrite(students);
        }
