crystalreport运行时错误 [英] crystalreport runtime error

问题描述

嗨 当我将数据表发送到reportdocument时，我有一个向我显示此错误的应用程序！ 请帮忙...
错误=
混合模式程序集是针对运行时版本"v2.0.50727"构建的，如果没有其他配置信息，则无法在4.0运行时中加载.

我的app.config文件是:

 <?  xml    版本  ="  ? > 
<  配置 > 
  <  启动    ="   true" <   supportedRuntime      ="   sku   . NETFramework，Version = v4.0" > 
  <  /startup  > 
<  /configuration  >  

但我看到此错误！！！

解决方案

基于此处的讨论: [<?xml version="1.0"?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration>

but i see this error!!!

解决方案

Based on the discussion here: mixed mode assembly is built against version ''2.0.50727''[^], it, looks like your C# project references a C++/CLI project that has not yet been updated to .NET 4.0. Open your C++/CLI project in VS 2010 and build it again. And then make sure your C# project is referencing the new DLL and not the old one.
