使用 C# 显示水晶报表

displaying a crystal report using c#(使用 C# 显示水晶报表)

问题描述

我对 C# 比较陌生，而且我从未使用过 Crystal Reports，所以如果我确实使用了不正确的术语，我深表歉意.我正在尝试显示由某些 C# 代码调用的报告.通过在这里跟踪很多线程，我设法提出了以下代码，它确实构建了一个调试.但是，当代码运行时，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.

代码如下:

private void forAllQualitiesToolStripMenuItem_Click(object sender, EventArgs e) {
    CrystalReportViewer rv = new CrystalReportViewer();
    string reportPath = @"C:Documents and Settings
pDesktopStockByStatus.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 HERECrystalReport1.rpt");
    crystalReportViewer1.ReportSource = cryRpt;
    crystalReportViewer1.Refresh();
