推荐答案

尝试以下语句-

Try the below statement -

rptdocument.Load(Server.MapPath("~\Report1.rpt"))

如果您仍然遇到错误，请告诉我们您存储Report1.rpt文件的路径以及尝试从中访问报告的页面位置.

In case you are still getting an error, let us know the path where you have stored the Report1.rpt file as well as the page location where you are trying to access the report from.

无效的报告文件路径"

rptdocument.Load(Server.MapPath("Report1.rpt"))

必须引发此错误.

显然是相对路径问题.您需要确保路径正确，以便找到并使用该文件.

我建议您使用此技巧并在设置源之前正确解析路径:

must be raising this error.

It clearly is relative path issue. You would need to make sure that the path is correct such that file is found and used.

I would suggest you to use this Tip and resolve the path correctly before setting the source: Resolving Paths in a Multi-Folder WebSite[^]
