EPPlus的通用Excel生成器功能

Question

如何为LINQ查询构建通用的EPPlus Spreadsheet函数？

更新:需要专门用于ASP.NET MVC应用程序.

Answer 1

我所做的就是创建一个接受List的通用函数.我使用反射来获取属性列表,这将成为我们的列标题.最后,我只是让EPPlus完成所有繁重的工作.

void ListToExcel<T>(List<T> query)
    {            
        using (ExcelPackage pck = new ExcelPackage())
        { 
            //Create the worksheet
            ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Result");

            //get our column headings
            var t = typeof(T);
            var Headings = t.GetProperties();
            for (int i = 0; i < Headings.Count(); i++)
            {

                ws.Cells[1, i+1].Value = Headings[i].Name;
            }

            //populate our Data
            if (query.Count() > 0)
            {
                ws.Cells["A2"].LoadFromCollection(query);
            }

            //Format the header
            using (ExcelRange rng = ws.Cells["A1:BZ1"])
            {
                rng.Style.Font.Bold = true;
                rng.Style.Fill.PatternType = ExcelFillStyle.Solid;                      //Set Pattern for the background to Solid
                rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189));  //Set color to dark blue
                rng.Style.Font.Color.SetColor(Color.White);
            }

            //Write it back to the client
            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.AddHeader("content-disposition", "attachment;  filename=ExcelDemo.xlsx");
            Response.BinaryWrite(pck.GetAsByteArray());
            Response.End();
        }
    }

现在有一种更简单的方法可以使用 LoadFromCollection 方法来实现这一点。

public void ExportToExcel(IEnumerable<Employee> employees, FileInfo targetFile)
{
    using (var excelFile = new ExcelPackage(targetFile))
    {
        var worksheet = excelFile.Workbook.Worksheets.Add("Sheet1");
        worksheet.Cells["A1"].LoadFromCollection(Collection: employees, PrintHeaders: true);
        excelFile.Save();
    }
}
