将数据导出到Excel C＃

我想用某些列自定义我的Excel输出结果。 现在我有导出excel工作好吗，但它显示太多列。 我想只出口某些列。 任何想法如何做到这一点？

public void ExportFilteredHistorydDataToExcel() { try { // getting session data from the grid var claims = (List<ClaimsArchived>)Session["allclaims"]; GridView gv = new GridView(); gv.DataSource = claims; gv.DataBind(); Response.Clear(); Response.Buffer = true; //Response.Charset = ""; //Response.ContentType = "application/vnd.ms-excel"; Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("content-disposition", "attachment;filename=filteredHistoryClaims.xls"); StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); gv.RenderControl(htw); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End(); } catch (Exception ex) { Console.WriteLine("There is a problem exporting data to Excel Spreadsheet.", ex); } } 

和模型

 public partial class ClaimsArchived { public int Claim_ID { get; set; } public String Provider { get { if (Provider_Group == 73) { return "CEP"; } else if (Provider_Group == 72) { return "CASE"; } else { return "???"; } } } [Display(Name = "Provider Num")] public Nullable<int> Provider_Group { get; set; } public string Facility { get; set; } public string Physician { get; set; } [Display(Name = "Last")] public string Patient_Last { get; set; } [Display(Name = "First")] public string Patient_First { get; set; } [Display(Name = "DOB")] [DataType(DataType.Date)] [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)] public Nullable<System.DateTime> Patient_DOB { get; set; } public int Age { get { DateTime date = DateTime.Today; DateTime birthday = Convert.ToDateTime(Patient_DOB); int tempage = date.Year - birthday.Year; return tempage; } } public string Funding_Type { get { DateTime date = DateTime.Today; DateTime birthday = Convert.ToDateTime(Patient_DOB); int compareAge = date.Year - birthday.Year; if (compareAge > 20) { return "MADDY"; } else { return "RICHIE"; } } } [Display(Name = "Gender")] public string Patient_Gender { get; set; } /// <summary> /// temp remove that from the output and export -- SSNs are sensitive information so that's why disabled in this case /// </summary> [Display(Name = "SSN")] [DisplayFormat(ApplyFormatInEditMode = false, DataFormatString = "{0:###-##-####}")] public Nullable<int> Patient_SSN { get; set; } [Display(Name = "Zip")] public string Patient_Zip { get; set; } public string Diagnosis { get; set; } [Display(Name = "Total Charges")] public Nullable<decimal> Total_Charges { get; set; } [Display(Name = "EMS Rate")] public Nullable<decimal> Total_EMS { get; set; } public bool Paid { get; set; } //public bool Paid { get; set; } [Display(Name = "Paid Date")] [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)] public Nullable<System.DateTime> Paid_date { get; set; } [Display(Name = "Unique ID")] public Nullable<int> Unique_ID { get; set; } [Display(Name = "Import Date")] [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)] public Nullable<System.DateTime> ImportDate { get; set; } [Display(Name = "Arh Date")] [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)] public Nullable<System.DateTime> ArchiveDate { get; set; } [Display(Name = "Archived")] public bool ArchiveYesNo { get; set; } } 

我想从Excel中删除四列，如SSN，导入date，交易date和存档列。 任何想法？ 谢谢！

  // hiding the column header -- Added code start here --- gv.HeaderRow.Cells[0].Visible = false; // hiding the column detail for (int i = 0; i < gv.Rows.Count; i++) { GridViewRow row = gv.Rows[i]; row.Cells[0].Visible = false; } // ------------------ Added code ended here ------ // following code are the same gv.RenderControl(htw); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End();
