LocalProccessingException未处理rdlc PDF c＃export

Question

我正在尝试编写一个函数来将rdlc报告作为pdf保存到指定位置，但是我得到了异常

  

“报告'Reports / AsrPhoneList.rdlc'的报告定义没有   被指定为“。

如果有任何多余的事情让我知道，我是新手。

void SaveReport()
{
     Warning[] warnings;
     string[] streamids;
     string mimeType;
     string encoding;
     string filenameExtension;
     string saveFilePath = string.Concat(@"c:\Users\", windowsUserName, @"\Desktop\CurrentStatus.pdf");
     ReportViewer reportViewer = new ReportViewer();
     reportViewer.LocalReport.ReportPath = "Reports/AsrPhoneList.rdlc";
     reportViewer.ProcessingMode = ProcessingMode.Local;
     byte[] bytes = reportViewer.LocalReport.Render(
            "PDF", null, out mimeType, out encoding, out filenameExtension,
            out streamids, out warnings);

     using (FileStream fs = new FileStream(saveFilePath, FileMode.Create))
     {
         fs.Write(bytes, 0, bytes.Length);
     }
}
