C# Epplus在Web项目中使用模板

我一直在.NET桌面项目（C#）上使用epplus，并使用如下模板：

var package = new ExcelPackage(new FileInfo("C:\\Templates\\FormatoReporteSamsung.xlsx"))

但现在我正在处理一个.NET Web项目（C#），我不知道如何引用像Web资源一样存在的模板，其中该资源的URI如下所示：

http://myownweb:29200/Content/excelTemplates/Formato.xlsx 

---

最后，我使用以下代码将excel模板作为流传递

using (var package = new ExcelPackage(new MemoryStream(GetBytesTemplate(FullyQualifiedApplicationPath + "Content/excelTemplates/Format.xlsx"))))
    {
        //Write data to excel

        //Read file like byte array to return a response
        Response.Clear();
        Response.ContentType = "application/xlsx";
        Response.AddHeader("content-disposition", "attachment; filename=" + "myFileName" + ".xlsx");
        Response.BinaryWrite(package.GetAsByteArray());
        Response.End();
    }

要读取包含字节的excel文件，我使用以下命令

以及获取我使用的网站的名称

您尝试过这个吗？：

var package=new ExcelPackage（“http://myownweb:29200/Content/excelTemplates/Formato.xlsx“”

是，它显示一个错误：不支持URI格式。

private byte[] GetBytesTemplate(string url)
        {
            HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(url);
            WebResponse myResp = myReq.GetResponse();

            byte[] b = null;
            using (Stream stream = myResp.GetResponseStream())
            using (MemoryStream ms = new MemoryStream())
            {
                int count = 0;
                do
                {
                    byte[] buf = new byte[1024];
                    count = stream.Read(buf, 0, 1024);
                    ms.Write(buf, 0, count);
                } while (stream.CanRead && count > 0);
                b = ms.ToArray();
            }

            return b;
        }

                //Getting the current context of HTTP request
                HttpContext context = HttpContext.Current;

                //Checking the current context content
                if (context != null)
                {
                    //Formatting the fully qualified website url/name
                    appPath = string.Format("{0}://{1}{2}{3}",
                      context.Request.Url.Scheme,
                      context.Request.Url.Host,
                      context.Request.Url.Port == 80
                        ? string.Empty : ":" + context.Request.Url.Port,
                      context.Request.ApplicationPath);
                }
                if (!appPath.EndsWith("/"))
                    appPath += "/";
                return appPath;
            }
        }
