 public class ReportsResult：ActionResult 
 {
 public ReportsResult（byte [] data，string mineType）

 this.Data = data; 
 this.MineType = mineType; 
} 
 
 public byte [] Data {get;组; }

} 

< pre lang =HTML> 
< div> 
 @ {
 Html.RenderAction（EmployeesNumberPerYear，EmployeeReports）; 
} 
< / div> 

解决方案

如果EmployeeReports是您的控制器，那么我会创建一个像这样的新方法：

  public   void  EmployeesNumberPerYearToPDF（）
 {
  string  dtatSetName =   DsENPerYear; 
  var  dataSource = 
 EmployeeReports.EmployeesNumberPerYear（employeeRepository）; 
  string  reportFilePath = 
 Server.MapPath（ 〜/ RDLC /雇员/ EmployeesNumberPerYear.rdlc）; 
  string  reportType =   PDF; 
 
  string  mimeType; 
  string 编码; 
  string  fileNameExtension; 
 
  byte  [] renderedBytes = 
 HotelReport.GenerateReport（dtatSetName，dataSource，reportFilePath，
 reportType， out  mimeType， out 编码， out  fileNameExtension）; 
 
 System.Web.HttpContext.Current.Response.ContentType = mimeType; 
 System.Web.HttpContext.Current.Response.BinaryWrite（renderedBytes）; 
 
} 

然后你可以在你的div中嵌入Google Doc Viewer（iframe）并指定PDF您要显示的文件，即在您的情况下将URL传递给控制器​​，该控制器将返回PDF文件的字节数组。这是您应该在div中添加的代码：

 <   iframe     src   =  http://docs.google.com/gview?url=@Url.Action(\"<  EmployeesNumberPerYearToPDF，   EmployeeReports，    null，   请求。 Url.Scheme）& embedded   =   true   样式  = 宽度：600px ; height：500px;    frameborder   =  0 >  <   / iframe  >  

<pre lang="c#">
public class ReportsResult : ActionResult
    {
        public ReportsResult(byte[] data, string mineType)
        {
            this.Data = data;
            this.MineType = mineType;
        }

        public byte[] Data { get; set; }
        public string MineType { get; set; }

        public override void ExecuteResult(ControllerContext context)
        {
            if (Data == null)
            {
                new EmptyResult().ExecuteResult(context);
                return;
            }
            context.HttpContext.Response.ContentType = MineType;

            using (MemoryStream ms = new MemoryStream(Data))
            {
                ms.Position = 0;
                using (StreamReader sr = new StreamReader(ms))
                {
                    context.HttpContext.Response.Output.Write(sr.ReadToEnd());
                }
            }
        }
    }

public static class HotelReport
   {
       public static byte[] GenerateReport(string dtatSetName, IEnumerable dataSource, string reportFilePath,
                              string reportType, out string mimeType, out string encoding, out string fileNameExtension)
       {

           ReportDataSource reportDataSource = new ReportDataSource(dtatSetName, dataSource);

           LocalReport localReport = new LocalReport();
           localReport.ReportPath = reportFilePath;
           localReport.DataSources.Add(reportDataSource);

           string deviceInfo =
               "<DeviceInfo>" +
               "  <OutputFormat>" + reportType + "</OutputFormat>" +
               "  <PageWidth>8.5in</PageWidth>" +
               "  <PageHeight>11in</PageHeight>" +
               "  <MarginTop>0.5in</MarginTop>" +

               "  <MarginBottom>0.5in</MarginBottom>" +
               "</DeviceInfo>";

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

           renderedBytes = localReport.Render(
               reportType,
               deviceInfo,
               out mimeType,
               out encoding,
               out fileNameExtension,
               out streams,
               out warnings);

           return renderedBytes;
       }
   }

public ActionResult EmployeesNumberPerYear()
        {
         string dtatSetName = "DsENPerYear";
         var dataSource = 
                 EmployeeReports.EmployeesNumberPerYear(employeeRepository);
         string reportFilePath = 
                 Server.MapPath("~/RDLC/Employee/EmployeesNumberPerYear.rdlc");
         string reportType = "PDF";

         string mimeType;
         string encoding;
         string fileNameExtension;

         byte[] renderedBytes = 
            HotelReport.GenerateReport(dtatSetName, dataSource, reportFilePath,
                reportType, out mimeType, out encoding, out fileNameExtension);

        return new ReportsResult(renderedBytes, mimeType);
        }

<pre lang="HTML">
<div>
    @{
        Html.RenderAction("EmployeesNumberPerYear", "EmployeeReports");
    }
</div>

解决方案

If EmployeeReports is your controller, then I'd create a new method like this:

public void EmployeesNumberPerYearToPDF()
        {
         string dtatSetName = "DsENPerYear";
         var dataSource = 
                 EmployeeReports.EmployeesNumberPerYear(employeeRepository);
         string reportFilePath = 
                 Server.MapPath("~/RDLC/Employee/EmployeesNumberPerYear.rdlc");
         string reportType = "PDF";
 
         string mimeType;
         string encoding;
         string fileNameExtension;
 
         byte[] renderedBytes = 
            HotelReport.GenerateReport(dtatSetName, dataSource, reportFilePath,
                reportType, out mimeType, out encoding, out fileNameExtension);
 
        System.Web.HttpContext.Current.Response.ContentType = mimeType;
        System.Web.HttpContext.Current.Response.BinaryWrite(renderedBytes);

        }

Then you could embed Google Doc Viewer (an iframe) in your div and specify the PDF file you want to display i.e. in your case pass the URL to your controller that will return the byte array of the PDF file. This is the code you should add inside your div:

<iframe src="http://docs.google.com/gview?url=@Url.Action("EmployeesNumberPerYearToPDF", "EmployeeReports", null, Request.Url.Scheme)&embedded=true" style="width:600px; height:500px;" frameborder="0"></iframe>
