========================我正在使用Visual Studio 2010. Crystal报表版本是13.0.2000我在web.config中输入了以下行

<add assembly="CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
        <add assembly="CrystalDecisions.ReportSource, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
        <add assembly="CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
        <add assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
        <add assembly="CrystalDecisions.ReportAppServer.ClientDoc, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>

当我通过视觉工作室2010中按F5来运行它时，我的水晶报告工作正常 .

目录结构

Reports / Dataset / Dataset1.xsd Reports / rpt / CrystalReport1.rot Reports / AgentList.aspx

导入的命名空间

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
Imports System.IO

代码隐藏

Dim reportpath As String = Server.MapPath("rpt/CrystalReport1.rpt")
com.CommandText = "SELECT  idAgent AS ID,AgentName,Add1 AS Address FROM PmAgentMaster"
com.Connection = conPatho
da.SelectCommand = com
dt.Rows.Clear()
If conPatho.State = ConnectionState.Closed Then conPatho.Open()
da.Fill(dt)
conPatho.Close()
Dim ds As New DataSet1()
ds.Tables(0).Merge(dt)
ShowPopUpMsg(reportpath)
Dim rptDoc As New ReportDocument()
rptDoc.Load(reportpath)
rptDoc.SetDataSource(ds)
CrystalReportViewer1.ReportSource = rptDoc

谁能帮我 . 请 .
