C# SQL错误：无法加载文件或程序集'；Microsoft.SqlServer.SqlClrProvider，

你好。 我犯了这个错误，我尝试了论坛上的所有建议，但没有成功。 单击“保存”按钮时，我的应用程序将创建一个SQL连接文件。这就是我得到的错误： 无法加载文件或程序集

Microsoft.SqlServer.SqlClrProvider，版本=13.100.0.0，区域性= 中性，PublickeyToken=89845dcd8080cc91'或其依赖项之一。 系统找不到指定的文件

代码：

以前有人遇到过这个问题吗？ 我正在使用c#Visual Studio 2015。SQL server 2016

非常感谢您。

您有Microsoft.SqlServer.SqlClrProvider的参考资料吗？它位于什么名称空间中。您似乎只导入了Microsoft.SqlServer.Management.Smo&Common？您缺少的程序集似乎实际安装在GAC中。这已经在前面的问题中讨论过了，谢谢。已经修好了。参考文献的版本不同。
