推荐答案

编码顺序错误。

首先你应该加载报告文件&然后将 ReportDocument 分配给 CrystalReportViewer 。所以它应该如下所示。

The order of coding is wrong.
First you should load the report file & then assign the ReportDocument to CrystalReportViewer. So it should be like below.

ReportDocument1.Load(StrPath);
crystalReportViewer1.ReportSource = ReportDocument1;
crystalReportViewer1.Refresh();

你的代码中不需要 PrintToPrinter 方法，因为你我只想查看报告。

And there's no need for PrintToPrinter method in your code because you wanted only to view the report.
