TransactionScope问题

Question

我在DB中有一个映射表，id为7，字段为Taex，值为"qwe“

在此代码中：

var fooObj = Foo.GetById(7);
fooObj.Taex = "abc";
using (new TransactionScope(OnDispose.Rollback))
{
    var originalFooObj = Foo.GetById(7);
    // how can i do to get real original object from database into a transaction
    bool areEquals = fooObj.Taex == originalFooObj.Taex; // are equals
    // because nhibernate gets the cached object.
}

我需要将数据库的原始数据放入事务中，我该怎么办？

Answer 1

NHibernate有Refresh方法。您可以使用它来强制NH从DB重新加载实体

Answer 2

你不是已经有了吗：

var fooObj = Foo.GetById(7);
var tempTaex = fooObj.Taex; //**get the original value
fooObj.Taex = "abc";
using (new TransactionScope(OnDispose.Rollback))
{
    var originalFooObj = Foo.GetById(7);
    // how can i do to get real original object from database into a transaction
    bool areEquals = fooObj.Taex == tempTaex; //**use it
    // because nhibernate gets the cached object.
}
