Question

我的应用有2个数据库，Db1（有表dbo.Student）和Db2（有表dbo.School）。我创建了2个AppService来访问它们当我尝试从两个数据中获取数据时，它仅使用与Db1的连接（在当前上下文中找不到表dbo.School）。那么如何才能同时从Db1和Db2获取数据

private readonly IStudentAppService _studentAppService;
private readonly ISchoolAppService _schoolAppService;

public BranchAccountController(IStudentAppService studentAppService,
ISchoolAppService schoolAppService)
{
     _studentAppService = studentAppService;
     _schoolAppService = schoolAppService;
}

public async Task<PartialViewResult> GetStudent(int? id)
{           
     //Repository 1 (Database 1)
     var student = await _studentAppService.GetStudentForEdit(new NullableIdDto { Id = id });
     //Repository 2 (Database 2)
     var school = await _schoolAppService.GetSchoolList();

     //bla bla      
}

更新1：我试着在学生面前上学，面对以下错误：传入的事务与当前事务无关连接。仅与当前连接关联的事务可以使用。
