[英]How to export data to excel in C# using Linq
我有以下控制器方法,該方法將返回模型中的數據。 如何將所有數據導出到Excel?
public ActionResult iDeal_Table_Display(Guid? SA = null)
{
var iDConfig = webservice.Get_iDealConfigs(SA,null,null,null,null,null,null, out retStatus, out errorMsg);
var model = iDConfig.Select(ic => new iDealModel2
{
SaPrefix = ic.PrefixName,
CalendarCode = ic.CalendarCodeName,
CashnCarry = ic.isCashnCarry,
FreeMM = ic.isFreeMM,
OnContract = ic.isOnContract,
ProductId = ic.ProductName,
RequestTypeId = ic.RequestTypeName
}).ToList();
return PartialView(model);
}
您可以使用DataTables並執行以下操作:
public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable();
products.Columns.Add("code", typeof(int));
products.Columns.Add("description", typeof(string));
// you can add your columns here as many you want
var a = db.ABC.Where(x => x.S2 == "ASSETS").FirstOrDefault();
var l = db.ABC.Where(x => x.S2 == "LIABILITIES").FirstOrDefault();
// in this way you can get data from database if you are using.. or u may use any other way to seed your file as per your need
products.Rows.Add(a.S1, a.S2, a.S39, a.S40);
products.Rows.Add(l.S1, l.S2, l.S39, l.S40);
// seeding the rows
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.ContentType = "application/application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AppendHeader("content-disposition", "attachment; filename=filename.xlsx");
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
對不起,第一個答案。 我找到了一種無需安裝Office參考的更好方法
public void toExcel()
{
var grid = new GridView();
var iDConfig = blergo.Get_iDealConfigs(null, null, null, null, null, null, null, out retStatus, out errorMsg);
var model = iDConfig.Select(ic => new iDealModel2
{
SaPrefix = ic.PrefixName,
CalendarCode = ic.CalendarCodeName,
CashnCarry = ic.isCashnCarry,
FreeMM = ic.isFreeMM,
OnContract = ic.isOnContract,
ProductId = ic.ProductName,
RequestTypeId = ic.RequestTypeName
}).ToList();
grid.DataSource = from data in model.OrderBy(x => x.SaPrefix)
select new
{
SAPrefix = data.SaPrefix,
CalendarCode = data.CalendarCode,
isCash = data.CashnCarry,
FreeMM = data.FreeMM,
onContract = data.OnContract,
Product = data.ProductId,
RequestType = data.RequestTypeId
};
grid.DataBind();
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=iDealConfig.xls");
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(sw);
grid.RenderControl(htmlTextWriter);
Response.Write(sw.ToString());
Response.End();
}
