普通调用方法
调用方法如下
须通过'DBTool.BeginTransaction()'开启事务调用'tran.Complete()'提交事务,不调用'tran.Complete()'当using结束会自动回滚
- 注意'DBTool.BeginTransaction()'必须使用using
using (var tran = DBTool.BeginTransaction())
{
var repository = GetRepository();
var deleteCount = repository.Delete(m => m.DataSource == "测试来源批量修改");
tran.Complete();
}
事务嵌套调用
事务支持嵌套,当嵌套时只有调用最外层的'tran.Complete()'才会提交事务.
using (var tran = DBTool.BeginTransaction())
{
using (var tran2 = DBTool.BeginTransaction())
{
var repository = GetRepository();
var deleteCount = repository.Delete(m => m.DataSource == "测试来源批量修改");
//下面这句话并不会提交事务
tran2.Complete();
}
//下面这句话会提交事务
tran.Complete();
}
