======================== 我正在使用 Visual Studio 2010。水晶报表版本是 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"/>

当我从 Visual Studio 2010 按 F5 运行水晶报表时，它运行良好。

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。

试试这个（注意波浪号）：

Server.MapPath("~/rpt/CrystalReport1.rpt")
