推荐答案

使用CrystalDecisions.CrystalReports.Engine;

使用CrystalDecisions.Shared;

使用CrystalDecisions.Shared.Interop;

使用System.IO;





bool status = false;

DataTable dt = new DataTable（ ）;

学生stu =新学生（）;

dt = stu.getActiveBlockStudentReport（0，Convert.ToString（ddlDepartment.SelectedValue），Convert.ToString（ddlCourses.SelectedValue） ），Convert.ToString（ddlStatus.SelectedValue））;

尝试

{

if（dt！= null && dt.Rows.Count> ; 0）

{

if（File.Exists（Server.MapPath（〜/ ActiveBlockStudent.Pdf）））

{

System.IO.File.Delete（Server.Ma pPath（ActiveBlockStudent.Pdf））;

}



string rptName = Server.MapPath（〜\\Reports \\ \\\rptBlockActiveStudent.rpt）;

ReportDocument RptDoc = new ReportDocument（）;

RptDoc.Load（rptName）;

RptDoc。 SetDataSource（dt）;

ExportOptions exportOpts1 = RptDoc.ExportOptions;
RptDoc.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;

RptDoc.ExportOptions。 ExportDestinationType = ExportDestinationType.DiskFile;

RptDoc.ExportOptions.DestinationOptions = new DiskFileDestinationOptions（）;

（（DiskFileDestinationOptions）RptDoc.ExportOptions.DestinationOptions）.DiskFileName = Server.MapPath（ ActiveBlockStudent.Pdf）;

RptDoc.Export（）;

RptDoc.Close（）;
RptDoc.Dispose（）;

{

Response.ClearContent（）;

Response.ClearHeaders（）;

Response.ContentType =application / pdf;

Response.AppendHeader（Content-Disposition，附件; filename = ActiveBlockStudent.Pdf）;

Response.WriteFile（ActiveBlockStudent.Pdf）;

Response.Flush（）;

回复.Close（）;

}

if（File.Exists（Server.MapPath（〜/ ActiveBlockStudent.Pdf）））

{

System.IO.File.Delete（Server.MapPath（ActiveBlockStudent.Pdf））;

}

status = true;

}

其他

{

status = false;

}

}

catch（例外情况）

{

status = false;

}

if（status == false）

{

Messagebox1.Show（No Record Found found。）;

}

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using CrystalDecisions.Shared.Interop;
using System.IO;


bool status = false;
DataTable dt = new DataTable();
Student stu=new Student();
dt = stu.getActiveBlockStudentReport(0,Convert.ToString(ddlDepartment.SelectedValue),Convert.ToString(ddlCourses.SelectedValue),Convert.ToString(ddlStatus.SelectedValue));
try
{
if (dt != null && dt.Rows.Count>0)
{
if (File.Exists(Server.MapPath("~/ActiveBlockStudent.Pdf")))
{
System.IO.File.Delete(Server.MapPath("ActiveBlockStudent.Pdf"));
}

string rptName = Server.MapPath("~\\Reports\\rptBlockActiveStudent.rpt");
ReportDocument RptDoc = new ReportDocument();
RptDoc.Load(rptName);
RptDoc.SetDataSource(dt);
ExportOptions exportOpts1 = RptDoc.ExportOptions;
RptDoc.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
RptDoc.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
RptDoc.ExportOptions.DestinationOptions = new DiskFileDestinationOptions();
((DiskFileDestinationOptions)RptDoc.ExportOptions.DestinationOptions).DiskFileName = Server.MapPath("ActiveBlockStudent.Pdf");
RptDoc.Export();
RptDoc.Close();
RptDoc.Dispose();
{
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=ActiveBlockStudent.Pdf");
Response.WriteFile("ActiveBlockStudent.Pdf");
Response.Flush();
Response.Close();
}
if (File.Exists(Server.MapPath("~/ActiveBlockStudent.Pdf")))
{
System.IO.File.Delete(Server.MapPath("ActiveBlockStudent.Pdf"));
}
status = true;
}
else
{
status = false;
}
}
catch (Exception ex)
{
status = false;
}
if (status == false)
{
Messagebox1.Show("No Record Found.");
}
