======================== 我使用Visual Studio 2010. Crystal报表版本为13.0。 2000 我已经进入了下面一行在web.config中

<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"/> 

我的水晶报表工作正常，当我从Visual Studio中按F5运行2010

目录结构

报告/数据集/ Dataset1.xsd Reports/rpt/CrystalReport1.rot 报告/ 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（注意波浪线）：

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