C#中用SqlServer2008执行事务
//在应用中需要绑定事务及时回滚，不然会出现脏数据，数据库操作要遵循C（consistence）A(Atomicity)I（Isolation）D（durable）几个原则。
以下是C#代码
public static void ExecuteTran(List SqlStringList){
SqlConnection conn=new SqlConnection(“server=localhost;database=aa;user=sa;pwd=123456”);
conn.open();
SqlCommand cmd=conn.CreateCommand();
SqlTransaction transaction=conn.BeginTransaction();
cmd.Connection=conn;
cmd.Transaction=transaction;
try{
for (int i = 0; i < SQLStringList.Count; i++)
{
cmd.CommandType = CommandType.Text;
cmd.CommandText = SQLStringList[i];
if (cmd.ExecuteNonQuery() < 0)
{
throw new Exception();
}
}
//提交事务
transaction.Commit();
}
catch (Exception ex)
{
transaction.Rollback();
}
finally
{
conn.Close();
conn.Dispose();
conn.Dispose();
}
}
