类似htis的东西：

//添加一个子报表
 CrystalDecisions.ReportAppServer.ReportDefModel.Section rasSection;
 CrystalDecisions.ReportAppServer.Controllers.SubreportClientDocument MyNewSub; //= new SubreportClientDocument（）;

 rasSection = rptClientDoc.ReportDefController.ReportDefinition.ReportHeaderArea.Sections [0];

//添加新的子报表（而不是导入）时，需要将ReportURL属性留空
 MyNewSub = rptClientDoc.SubreportController.ImportSubreport（"世界销售报告"，" d：\\ atest \\ soda \\ impsub.rpt"，rasSection）;
 MyNewSub.DatabaseController.LogonEx（" YourServer"，" xtreme"，" sa"，" Password"）;


//更改现有的子报表
 CrystalDecisions.CrystalReports.Engine.ReportObjects crReportObjects;

//将crSections对象设置为当前报表的各节
 CrystalDecisions.CrystalReports.Engine.Sections crSections = rpt.ReportDefinition.Sections;

 如果（resultField.ToString（）=="世界销售报告.rpt"）
 {
    //循环遍历所有部分以查找所有报告对象
     foreach（CrystalDecisions.CrystalReports.Engine.Section crSection in crSections）
     {
         crReportObjects = crSection.ReportObjects;
        //循环遍历所有报表对象以查找所有子报表
         foreach（crReportObjects中的CrystalDecisions.CrystalReports.Engine.ReportObject crReportObject）
         {
             如果（crReportObject.Kind == ReportObjectKind.SubreportObject）
             {
                 CrystalDecisions.ReportAppServer.ReportDefModel.Section rasSection;
                 rasSection = rptClientDoc.ReportDefController.ReportDefinition.FindSectionByName（crSection.Name）;
                 CrystalDecisions.ReportAppServer.Controllers.SubreportClientDocument MyNewSub;
                 MyNewSub = rptClientDoc.SubreportController.GetSubreport（resultField.ToString（））;

                 CrystalDecisions.ReportAppServer.ReportDefModel.SubreportObject objSubreport = rptClientDoc.ReportDefController.ReportObjectController.GetAllReportObjects（）[crReportObject.Name]作为CrystalDecisions.ReportAppServer.ReportDefModel.SubreportObject;
                 CrystalDecisions.ReportAppServer.ReportDefModel.SubreportObject objSubreport2 =（CrystalDecisions.ReportAppServer.ReportDefModel.SubreportObject）objSubreport.Clone（true）;
                 rptClientDoc.ReportDefController.ReportObjectController.Remove（objSubreport）;
                 CrystalDecisions.ReportAppServer.ReportDefModel.SubreportLinks mySubLinks = rptClientDoc.SubreportController.GetSubreportLinks（objSubreport2.SubreportName.ToString（））;
                 mySubLinks.RemoveAll（）;

                 objSubreport2.Left = 10;
                 objSubreport2.Height = 10;
                 objSubreport2.Width = 10;
                 objSubreport2.Name =" sub1";
                 objSubreport2.SubreportName =" sub1";
                //rptClientDoc.ReportDefController.ReportObjectController.Modify(rptClientDoc.ReportDefController.ReportObjectController.GetAllReportObjects()[crReportObject.Name] as CrystalDecisions.ReportAppServer.ReportDefModel.SubreportObject，objSubreport2）;
                 rptClientDoc.ReportDefController.ReportObjectController.Add（objSubreport2，rasSection，-1）;
             }
         }
     }
 } 

嗨唐

您能帮我提供样品吗？

要能够正常更改名称，您将使用RAS，这是一个只读属性：

字符串名称{get; }
CrystalDecisions.ReportAppServer.Controllers.ISCRSubreportClientDocument的成员

您需要做的就是克隆子报表并更改其名称，然后删除旧的子报表并将克隆的对象添加回报表中。
