表格CrTables;

CrTables = cryRpt.Database.Tables;

foreach（CrTables中的CrystalDecisions.CrystalReports.Engine.Table CrTable）

TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();

CrTables = cryRpt.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
{
crtableLogoninfo = CrTable.LogOnInfo;
crtableLogoninfo.ConnectionInfo = crConnectionInfo;
CrTable.ApplyLogOnInfo(crtableLogoninfo);

推荐答案

您的报告似乎期望参数字段的值在报告中定义。



最简单的方法是打开报告并查看定义。请参阅 Crystal Reports参数 [ ^ ]

It seems that your report is expecting values for parameter fields that are defined in the report.

The easiest way is to open the report and have a look at the definitions. Refer to Crystal Reports Parameters[^]
