Question

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
HttpContext.Current.Response.AddHeader("content-disposition", String.Format(@"attachment;filename={0}.xlsx", sheetName.Replace(" ", "_")));

using (var memoryStream = new MemoryStream())
{
    wb.SaveAs(memoryStream);
    memoryStream.WriteTo(HttpContext.Current.Response.OutputStream);
    memoryStream.Close();
}

HttpContext.Current.Response.End();

我想要SaveAs对话框显示默认指定路径，例如c：\ users \ joe \或将文件保存在指定目录中？我怎么能这样做？

Answer 1

您可以尝试为Application对象设置DefaultFilePath。

wb.Application.DefaultFilePath = @"c:\users\joe";
