Question

我有两个使用CR运行时生成reprts的WinForm应用程序。当安装CR运行时13.20时，较新的应用程序会抱怨它无法找到并加载CR 13.21（13.0.350）程序集。如果我将CR运行时升级到13.21（13.0.350），那么新应用程序将起作用，但较旧的应用程序会出现异常，并说明它无法找到并加载CR运行时程序集13.20（13.0.200）。所有工作站都在CR运行时13.20上运行，那么如何使用CR 13.21环境在VS2015中创建新应用程序在较旧的CR运行时上正常运行？

Answer 1

首先，从旧应用程序中删除CR Runtime引用，并添加对CR 13.21的引用。

Answer 2

我有同样的问题。客户端计算机的应用程序使用13.0.20，而我的应用程序使用13.0.21。我的参考设置为13.0.21。但我们遇到的问题是13.0.21的SAP安装程序强迫我们从客户端工作站删除13.0.20。因此，所有其他应用程序都会发现程序集未找到错误。

有没有办法同时安装20和21？

Answer 3

您需要升级引擎以匹配您拥有的最新版本。以我为例。我的引擎在13.2上运行，而我拥有的最新.dll文件是13.5，因此，使用Nuget控制台，您可以直接从Visual Studio升级引擎（例如Install-Package CrystalReports.Engine -Version 13.0.3500）

Answer 4

您可以告诉“旧的Crystal运行时应用程序”使用新的Crystal Reports运行时。您要做的就是在app.config文件中创建AssemblyBindings：

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
          <dependentAssembly>
            <assemblyIdentity name="CrystalDecisions.Shared" publicKeyToken="692fbea5521e1304" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-13.0.3500.0" newVersion="13.0.3500.0" />
          </dependentAssembly>
          [...]
    </assemblyBinding>

Answer 5

您可以使用配置文件重定向旧应用程序以使用较新的运行时。使用记事本在旧应用程序（使用较旧的Crystal运行时的应用程序）所在的文件夹中创建文件名 your_old_app_exe_name.exe.config ：

<?xml version="1.0" encoding="utf-8"?>

<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
