我正在C#visual studio 2012 RC中构建应用程序.

我必须在应用程序中运行脚本.为此,我正在使用.这两个库.我的应用程序的目标.net框架是4.5.

using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;

在检查天气数据库是否存在后,我编写了运行脚本的代码.

当我运行代码时会弹出一个意外的异常.我真的知道这是什么意思.你可以帮助我摆脱这个例外.

看起来你正在尝试加载.net 2版本的Microsoft.SqlServer.xxxx.dll.更新对.net4版本的引用(首选),或将以下口头禅添加到<configuration>节点下的app.config中

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
  <requiredRuntime version="v4.0" />
</startup>

允许加载.net 2程序集.详情请见此处.
