我们知道mvc可以通过js生成excel文件，同样在后台c#中一样可以生成excel文件。

　　首先我们要在后台中写如下方法：

　　

[HttpGet] public FileResult excel_generation(string userid,string count,string order_id,string order_name,string rec_person,string height,string shoulder_width,string sleeve_length,string phone,string weight,string breast,string upper_hip,string size,string waist,string pants_length,string age,string hip,string thigh,string price,string userrmk,string address, string imgs,string mianliaormk="",string nanyi ="",string logo="",string gencustom="",string bodyspacial="",string isredo="否",string color="原图色",string mianliaohoudu="",string mianliaotanli="")        {            var excel_text = new System.Text.StringBuilder();            //excel_text.Append("
     
      ");            excel_text.Append("
     
      ");            excel_text.Append("
       ");            excel_text.Append("
        ");            excel_text.Append("

　　我们看到，在c#中导出excel，这种方法可以通过画html中table的方式做出excel，而这种方法导出的表格是一个简单表格，在排版上还需要更多的斟酌。

　　在前台的时候，务必要注意，不可使用ajax，可以通过使用使用localtion.href="/控制器/excel_generation?参数=参数值"的方法导出表格。
