Please help me.
Thanks in advance

What I have tried:

Dim ReportViewer1 As Microsoft.Reporting.WebForms.ReportViewer = New Microsoft.Reporting.WebForms.ReportViewer()
     ReportViewer1.LocalReport.DataSources.Clear()
     ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote

     ReportViewer1.ServerReport.ReportServerUrl = New Uri("http://localhost:56370/NVSehore29jun18/")
     ReportViewer1.ServerReport.ReportPath = System.Web.Hosting.HostingEnvironment.MapPath("~/PartyFiles/General/ZSLedger001.rdlc")
     Dim rds As New Microsoft.Reporting.WebForms.ReportDataSource("DataSet1", dt)
     ReportViewer1.LocalReport.DataSources.Add(rds)
     ReportViewer1.LocalReport.Refresh()

     bytes = ReportViewer1.LocalReport.Render("PDF", Nothing, mimeType, encoding, extension, streamids, warnings)

     Dim fs As FileStream = New FileStream(FilePath, FileMode.Open)
     fs.Write(bytes, 0, bytes.Length)
     fs.Close()

推荐答案

您应该验证RDL的路径（如果存在）。请将此讨论读作： c＃4.0 - 来源尚未指定报告定义 - Stack Overflow [ ^ ]



PS：尝试调试代码，设置断点和进入你的代码，看看错误引发的位置。

You should verify the path to your RDL if it exist. Please give this discussion a read: c# 4.0 - The source of the report definition has not been specified - Stack Overflow[^]

PS: Try to debug your code, set a break point and step into your code to see figure out where the error is thrown.
