reportViewer.LocalReport.ReportPath = "Report1.rdlc"; --------------------编程问答-------------------- 1楼别误人子弟 --------------------编程问答-------------------- 楼主代码放在【code=C#】【/code】里啊 --------------------编程问答-------------------- 看一下这个路径：report.LocalReport.ReportPath = Application.StartupPath + "\\" +rdlcName; 是不是不对啊，一般报表自动生成的不会在这个路径下啊：Application.StartupPath
--------------------编程问答-------------------- 大家都回复了，路径

补充：.NET技术 ,  C#
