asp.net - 使用 Crystal Report 引用将 ASP.NET 2005 迁移到 2008 问题

Question

ASP.NET网站是使用VS.NET 2005版本开发的，并使用了Crystal Reports。
现在同样想升级到 VS.NET 2008，但它显示如下错误:

Error 469 Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified. C:\Documents and Settings\Administrator\Desktop\SVSS\ssvs10022010123\Web.Config 29

在 web.config 文件中，代码的编写方式与此错误所指的位置相同。

<compilation debug="true">
        <assemblies>
            <add assembly="CrystalDecisions.CrystalReports.Engine, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>

            <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/></assemblies></compilation>

Crystal Reports 已安装(VS2008 默认附带)。我们需要更改引用吗？
请指导我如何解决此问题。

最好的解决方案是在服务器上安装相同的运行时。
无论如何，您可以在 app.config 或 web.config 中使用此 XML:

  <runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="CrystalDecisions.CrystalReports.Engine" publicKeyToken="692fbea5521e1304" culture="neutral"/>
        <bindingRedirect oldVersion="xx.x.xxxx.x" newVersion="yy.y.yyyy.y"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="CrystalDecisions.Shared" publicKeyToken="692fbea5521e1304" culture="neutral"/>
        <bindingRedirect oldVersion="xx.x.xxxx.x" newVersion="yy.y.yyyy.y"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="CrystalDecisions.ReportSource" publicKeyToken="692fbea5521e1304" culture="neutral"/>
        <bindingRedirect oldVersion="xx.x.xxxx.x" newVersion="yy.y.yyyy.y"/>
      </dependentAssembly>
      <dependentAssembly>
        ...
    </assemblyBinding>
  </runtime>

其中oldVersion是您用于开发的版本，newVersion是服务器上安装的版本
