Question

我需要以PDF格式将水晶报告导出到本地系统。

我使用了ExporttoDesk但它保存在Server.I需要让用户可以使用。

可能吗？

我使用ExporttoStream。但它也不适用于我。

请告诉我实现这一目标的方法。

谢谢，勒凯什。

有参数时该怎么做？

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim Report As ReportDocument = New ReportDocument()
        Report.Load(Server.MapPath("~/CrystalReport.rpt"))
        Report.SetDatabaseLogon("sa", "######", "IT250WS", "demo")
        CrystalReportViewer1.ReportSource = Report
    End Sub

    Protected Sub btnPDF_Click(ByVal sender As Object, ByVal e As EventArgs)
        Dim Report As ReportDocument = New ReportDocument()
        Report.Load(Server.MapPath("~/CrystalReport.rpt"))
        Report.SetParameterValue("@EmpId", 1)
        Report.SetDatabaseLogon("sa", "######", "IT250WS", "demo")
        Response.Buffer = False
        Response.ClearContent()
        Response.ClearHeaders()
        Report.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, True, "File_Name")
        Response.[End]()
    End Sub

对于答案来说已经太晚了，但对于像我这样的人来说这可能是有用的。

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;

protected void Page_Load(object sender, EventArgs e)
    {
        ReportDocument pdfReport = new ReportDocument();
        pdfReport.Load(Server.MapPath("ExportToPdf.rpt"));
        pdfReport.SetDatabaseLogon("amitjain","password", @"AMITJAIN\SQL", "Northwind");
        CrystalReportViewer1.ReportSource = pdfReport;
    }

    protected void btnExport_Click(object sender, EventArgs e)
    {
        ReportDocument pdfReport = new ReportDocument();
        pdfReport.Load(Server.MapPath("ExportToPdf.rpt"));
        pdfReport.SetDatabaseLogon("user", "password", @"AMITJAIN\SQL", "Northwind");
        Response.Buffer = false;
        Response.ClearContent();
        Response.ClearHeaders();
        pdfReport.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, "Employees");
        Response.End();
    }
