c# - 将定义的名称放在 asp.net c# 的 reportviewer PDF 中

Question

我有这段代码，它的作用是为我生成一个PDF 或 EXCEL。我如何定义 moneto 以可视化或下载给我这个名字。例子EXCEL.excel 或 PDF.pdf我正在寻找定义固定名称示例的方法rodo.pdf 或 rodo.excel

public ActionResult print(ParametrosGeneral param, string id, FormCollection TipoReporte)
{

string Format = "pdf";
//  string Format = "excel";


LocalReport lr = new LocalReport();
string path = System.IO.Path.Combine(Server.MapPath("~/Reportes"), "Libro.rdlc");

if (System.IO.File.Exists(path))
{
    lr.ReportPath = path;
}
else
{
    return View("Index");
}

ReportDataSource rd = new ReportDataSource("DSLibro", LibroVenta(4, 2018).Tables[0]);    //here returns my query with the meters for 4 and 2018 that I send
lr.DataSources.Add(rd);

string reportType = Format;
string mineType;
string encoding;
string fileNameExtension;

string deviceInfo =
    "<DeviceInfo>" +
    "<OutputFormat>" + Format + "</OutputFormat>" +
    "<PageWidth>11in</PageWidth>" +
    "<PageHeight>8.5in</PageHeight>" +
    "<MarginTop>0,787402in</MarginTop>" +
    "<MarginLeft>0,787402in</MarginLeft>" +
    "<MarginRight>0,787402in</MarginRight>" +
    "<MarginBottom>0,787402in</MarginBottom>" +
    "</DeviceInfo>";

Warning[] warnings;
string[] streams;
byte[] renderedBytes;

renderedBytes = lr.Render(
        reportType,
        deviceInfo,
        out mineType,
        out encoding,
        out fileNameExtension,
        out streams,
        out warnings);

return File(renderedBytes, mineType);
}

按照这些思路尝试。文件名将是 somepdf.pdf

var cd = new System.Net.Mime.ContentDisposition
{
    FileName = "somepdf.pdf",
    Inline = true
};
Response.Headers.Add("Content-Disposition", cd.ToString());

return File(bytes, "application/pdf");
