Question

我正在使用带有Effort的Entity Framework，它使用NMemory进行测试，而不会产生实际的数据库副作用。有没有办法查看被发送到nmemory数据库的sql？

修改感谢@Gert_Arnold，我一直在寻找DbContext.Database.Log。不幸的是我的输出如下所示。任何人都可以评论这个吗？我假设我得到这些空条目而不是我的sql。

您可以截取并记录命令。

 // Before command is sent tell EF about the new interceptor
 DbInterception.Add(new MyEFDbInterceptor());


// The interceptor class is called by , see the various interface methods
// just a couple shown here.
public class MyEFDbInterceptor: IDbCommandInterceptor   {
  public void ReaderExecuting(DbCommand command, DbCommandInterceptionContext<DbDataReader> interceptionContext)    {
     Debug.Writeln(command.CommandText );
     //Debug.Writeln(interceptionContext.Result ); // might be interesting use
}

 public void ReaderExecuted(DbCommand command, DbCommandInterceptionContext<DbDataReader> interceptionContext)
{
  Debug.Writeln(command.CommandText );

}

 }

有没有办法使用sql profiler for nmemory（内存数据库）
