[英]Response.end doesn't work
我嘗試使用Response.End()
和OpenXml下載.xlsx
文檔。 但是什么也沒發生。 它卡在Response.End()
public void DownloadStudents(int InstituteId, int DepartmentId)
{
var memoryStream = new MemoryStream();
using (var spreadsheetDocument = SpreadsheetDocument.Create(memoryStream, SpreadsheetDocumentType.Workbook))
{
//Some code
foreach (var line in users)
{
// Fill
}
spreadsheetDocument.WorkbookPart.Workbook.Save();
}
var excelName = "Title.xlsx";
Response.Clear();
Response.CacheControl = "Private";
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("Content-Type", "application/octet-stream");
Response.AppendHeader("content-disposition",string.Format("attachment; filename={0}; size={1}", excelName, memoryStream.Length));
Response.BinaryWrite(memoryStream.ToArray());
**//Problem is here.**
Response.End(); // In this line nothing happens
}
當我嘗試使用Response.Flush()
時,也會出現相同的問題。 如果我使用CompleteRequest()
代替Response.End()
xlsx文件為空
這對我適用於所有文件:
public static void outputFile(FileContentResult file, String contentDisposition)
{
var context = System.Web.HttpContext.Current;
file.FileDownloadName = contentDisposition;
context.Response.Clear();
context.Response.ClearContent();
context.Response.ClearHeaders();
context.Response.AppendHeader("content-disposition", contentDisposition);
context.Response.ContentEncoding = System.Text.Encoding.UTF8;
context.Response.ContentType = file.ContentType;
context.Response.AppendHeader("content-length", file.FileContents.Length.ToString());
context.Response.BinaryWrite(buffer: file.FileContents.ToArray());
context.Response.Flush();
context.ApplicationInstance.CompleteRequest();
}
FileContentResult是在MVC中使用Controller類的File方法的結果。
我還相信您所缺少的是在嘗試輸出工作簿之前將其關閉。
我建議在嘗試將其輸出到視圖之前,先將電子表格Document.Close()后跟memoryStream.Flush()添加到您的代碼中。
contentDisposition只是String.Format(“ attachment; filename = {0}”,fileName)。
另外,Response.End()會引發錯誤,因此請始終使用另一個錯誤。
