如何在实体框架中使用事务?

问题描述

当你有这样的代码时:

Something something = new Something();
BlahEntities b = new BlahEntities()
b.AddToSomethingSet(something);
b.SaveChanges();

如何在事务中运行该添加?

how do run that addition inside a transaction?

推荐答案

您可以将代码置于事务范围内

You can place your code within a Transaction scope

using(TransactionScope scope = new TransactionScope())
{
    // Your code
    scope.Complete(); //  To commit.
}

TransactionScope 位于 System.Transactions 命名空间中，该命名空间位于同名程序集中(您可能需要手动将其添加到您的项目中).

TransactionScope is in the System.Transactions namespace which is located in the assembly of the same name (which you may need to add manually to your project).
