标题[问题] 有什麽 继承 的好办法?
时间Sat Mar 9 16:43:46 2019
各位大大好，个人想询问继承的问题，
假设我有个方法执行内容完全，只有在继承的时候需要多了一些判断
想询问该怎麽撰写会比较好?
下面是情境举例，
想问有人有好解法吗?
----- 举例 -----
我有个父类别 BackgroundWorker Call_DoWork 执行如下
bool stop = false;
protected void Call_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
bool complete = false;
while(!worker.CancellationPending & !stop & !complete)
{
Step1();
if(
!worker.CancellationPending & !stop)
Step2();
if(
!worker.CancellationPending & !stop)
Step3();
if(
!worker.CancellationPending & !stop)
{
Step4();
complete = true;
}
}
}
我有个子类别继承父类别并override Call_DoWork 如下
override protected void Call_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
bool complete = false;
while(!worker.CancellationPending & !stop & !complete &
rs232.IsOpen)
{
Step1();
if(
!worker.CancellationPending & !stop &
rs232.IsOpen)
Step2();
if(
!worker.CancellationPending & !stop &
rs232.IsOpen)
Step3();
if(
!worker.CancellationPending & !stop &
rs232.IsOpen)
{
Step4();
complete = true;
}
}
}
