我创建了一个 Crystal Report 并将其连接到位于C:\SomeDir\Data.xml.

在运行时，我可能需要将数据放入C:\SomeOtherDir\Data.xml.

到目前为止，我的代码如下所示：

ReportDocument report = new ReportDocument();
report.Load("Report.rpt");
PrinterSettings printerSettings = new PrinterSettings();
PageSettings pageSettings = printerSettings.DefaultPageSettings;
report.PrintToPrinter(printerSettings, pageSettings, false);

这将打印带有数据的报告C:\SomeDir\Data.xml。我希望它在C:\SomeOtherDir\Data.xml.

我怎样才能做到这一点？

ReportDocument report = new ReportDocument();
report.Load("Report.rpt");

DataSet reportData = new DataSet();
reportData.ReadXml(@"C:\SomeOtherDir\Data.xml");
report.SetDataSource(reportData);

PrinterSettings printerSettings = new PrinterSettings();
PageSettings pageSettings = printerSettings.DefaultPageSettings;
report.PrintToPrinter(printerSettings, pageSettings, false);

如果 XML 的架构发生变化，您需要在 CR 编辑器中打开报表并“验证数据库”以更新其绑定的架构，否则会抛出神秘的“登录失败”错误。

在 Java 中，如果我希望在运行时替换一组新数据，我通常会加载该数据（无论是来自 db 或 xml 的结果集还是其他），然后通过 rpt.Database.Tables.setDataSource 将其推送原始数据的“表别名”，因此 CR 知道要覆盖什么。在 C# 中可能会类似。您可能想复习一下，尝试一下，然后再提出更多问题。

如果您需要从头开始，请考虑您需要使用 XML 在 Crystelreport 中打印 DataGridView 数据

**(This is very helpful if you not using any database)**
  1. 首先制作数据表
  2. 然后将数据添加到数据表（这里从 DataGridview 添加）
  3. 制作 XML 文件
  4. 运行报告

这里示例代码

 DataTable dt = new DataTable();
 dt.Columns.Add("Item_Id", typeof(string));
 dt.Columns.Add("Categry", typeof(string));
 dt.Columns.Add("Item_Name", typeof(string));
 dt.Columns.Add("Unit_Price", typeof(double));
 dt.Columns.Add("Quantity", typeof(int));
 dt.Columns.Add("Discount", typeof(string));
 dt.Columns.Add("Total_Payable", typeof(double));
  foreach (DataGridViewRow dgr in DGVsell.Rows) 
 {
   dt.Rows.Add(dgr.Cells[0].Value, dgr.Cells[1].Value, dgr.Cells[2].Value, dgr.Cells[3].Value, dgr.Cells[4].Value, dgr.Cells[5].Value, dgr.Cells[6].Value);
 }
 ds.Tables.Add(dt);
 ds.WriteXmlSchema("Bill.xml");

注意如果在制作 Xml 更改App.config文件时出错，如下所示

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  </startup>-->
    <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

生成xml文件后，可以调用Crystel报告

 frmreport obj = new frmreport(); //load report viwer form
 obj.ShowDialog();

在报告查看器中

crBill cr = new crBill();
cr.SetDataSource(frmSell.ds);
crystalReportViewer1.ReportSource = cr;
crystalReportViewer1.RefreshReport();
crystalReportViewer1.Refresh();
