我想使用mvc3从sql server下载不同的列数据。例如,我想从表帐户中下载5列,其中id = 1,以及2列来自产品,其中id = 1。任何人都可以为我提供一些教程或任何链接来实现这一目标。感谢

public ActionResult ExportCsv(int page, string orderBy, string filter)
{
IEnumerable orders = GetOrders().AsQueryable().ToGridModel(page, 10, orderBy, string.Empty, filter).Data;
MemoryStream output = new MemoryStream();
StreamWriter writer = new StreamWriter(output, Encoding.UTF8);
writer.Write("OrderID,");
writer.Write("ContactName,");
writer.Write("ShipAddress,");
writer.Write("OrderDate");
writer.WriteLine();
foreach (Order order in orders)
{
writer.Write(order.OrderID);
writer.Write(",");
writer.Write("\"");
writer.Write(order.Customer.ContactName);
writer.Write("\"");
writer.Write(",");
writer.Write("\"");
writer.Write(order.ShipAddress);
writer.Write("\"");
writer.Write(",");
writer.Write(order.OrderDate.Value.ToShortDateString());
writer.WriteLine();
}
writer.Flush();
output.Position = 0;
return File(output, "text/comma-separated-values", "Orders.csv");
}
有关详细信息,请访问Telerik Demos。您不需要使用telerik来实现此功能。只需编写actionresult,获取数据将其转换为csv,从浏览器调用它就完成了。
