使用C＃显示水晶报表 [英] displaying a crystal report using c#

问题描述

我是C＃的新手，我从未使用过Crystal Reports，因此如果我使用的术语不正确，我深表歉意。我正在尝试显示由某些C＃代码调用的报告。通过在此处跟踪许多线程，我设法提出了以下代码，这些代码的确建立了调试。但是，运行代码时，它不会显示报告。

I am relatively new to C# and i have never used Crystal Reports so i apologise if i do use the incorrect terminology. I am trying to display a report which is called by some C# code. By following a lot of threads on here, i have managed to come up with the following code which does build an debug. However, when the code is run, it does not display the report.

这里是代码：

private void forAllQualitiesToolStripMenuItem_Click(object sender, EventArgs e) {
    CrystalReportViewer rv = new CrystalReportViewer();
    string reportPath = @"C:\Documents and Settings\rp\Desktop\StockByStatus.rpt"; 

    ReportDocument r = new ReportDocument();

    r.Load(reportPath);
    rv.Visible = false; // i put this in because when i ran the code without it, it said the report must not be visible and the program would fall down
    rv.ReportSource = r;
    rv.InitReportViewer();
    ShowDialog(rv);
}

推荐答案

    ReportDocument cryRpt = new ReportDocument();
    cryRpt.Load(@"CRYSTAL REPORT PATH HERE\CrystalReport1.rpt");
    crystalReportViewer1.ReportSource = cryRpt;
    crystalReportViewer1.Refresh();
