copied!<p>Try this, you can get the <code>Request</code> and <code>Response</code> directly off <code>HttpContext.Current</code>:</p> <pre><code>public static void SendExcelFile(string downloadFileName, List<List<string>> data, string worksheetTitle) { var context = HttpContext.Current; string tempFolder = context.Request.PhysicalApplicationPath + "temp"; string tempFileName = tempFolder + "tempFileName.xlsx" if (!Directory.Exists(tempFolder)) Directory.CreateDirectory(tempFolder); // Generate file using ExcelPackage GenerateExcelDoc(tempFileName, data, worksheetTitle); context.Response.AddHeader("Content-Disposition", "attachment;filename=" + downloadFileName); context.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; context.Response.AddHeader("Content-Length", new FileInfo(tempFileName).Length.ToString()); context.Response.TransmitFile(tempFileName); File.Delete(tempFileName); } </code></pre> <p>Another alternative is a base class for your pages that contains this method, that may be a much easier route. You pages don't have to inherit from System.Web.UI.Page, they can inherit from something else, like this:</p> <pre><code>public class BasePage : System.Web.UI.Page { public void SendExcelFile(string downloadFileName, List<List<string>> data, string worksheetTitle) { string tempFolder =Request.PhysicalApplicationPath + "temp"; string tempFileName = tempFolder + "tempFileName.xlsx" if (!Directory.Exists(tempFolder)) Directory.CreateDirectory(tempFolder); // Generate file using ExcelPackage GenerateExcelDoc(tempFileName, data, worksheetTitle); Response.AddHeader("Content-Disposition", "attachment;filename=" + downloadFileName); Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("Content-Length", new FileInfo(tempFileName).Length.ToString()); Response.TransmitFile(tempFileName); File.Delete(tempFileName); } } </code></pre> <p>Then in your page the class looks like:</p> <pre><code>public partial class MyPage : BasePage { //Stuff! } </code></pre>
