问题描述
我正在使用c＃.net开发一个Windows窗体应用程序，在我的应用程序中，我想使用form1中的日期时间选择器输入开始日期和结束日期，并且需要在所选日期之间打开包含数据的水晶报表form2作为一个新窗口我已经设计了水晶报告，报告工作正常。然后设计form2与水晶报表查看器来查看报告。但我不知道如何将form1中的日期（参数）传递给包含水晶报表查看器的form2。请有人可以帮我这样做。
尝试使用以下代码，但没有任何反复
我尝试了什么：
myDataSet ds = new myDataSet（）;
frm_ReportViewer viewForm = new frm_ReportViewer（）;
viewForm.Owner = this;
rpt_myreport report = new rpt_myreport（）;
report.Load（Reports \\rpt_myreport。 rpt）;
report.SetDataSource（ds）;
viewForm.crv_common.ReportSource = report;
viewForm.ShowDialog（this）;

viewForm.crv_common.ReportSource = report;
viewForm.ShowDialog(this);
