如果您在Visual Studio 2013（dotNET 4.0或4.5）中编译了较旧的Crystal Report Viewer dotNET项目（2.0或3.5）并得到相同的错误，我的解决方案是在web.config中指定Crystal DLL的绑定重定向到特定版本。更多信息：

尝试删除这两个副本并重新安装运行时引擎以清除所有这些。

Answer 4

我是一名网络程序员，我在2013版本和水晶报告中工作。我只是在解决这个问题。

首先你去你的asp.net项目，然后点击 bin 文件夹看到水晶报告dll保存在这里。删除所有水晶报告DLL 在bin文件夹中，然后重新启动您的项目。就是这样。
