c# - 相似函数重构模式

Question

我有大约 20 个具有几乎相同模式的函数，我在 Sites 数组上运行，使用 Site 对象创建 SiteOperation 并执行一些操作(在这种情况下使用一个参数，但有时没有或更多)

int wantedBandwidthInLBps = 2048 / 8;
foreach (Sites site in _sitesManagement.GetAll())
{
 SiteOperation siteOperation = new SiteOperation(site);
 siteOperation.LimitBandwidth(wantedBandwidthInLBps);
}

foreach (Sites site in _sitesManagement.GetAll())
{
 SiteOperation siteOperation = new SiteOperation(site);
 siteOperation.KillJames();
}

foreach (Sites site in _sitesManagement.GetAll())
{
 SiteOperation siteOperation = new SiteOperation(site);
 siteOperation.FlyToMoon(2012, new TaskIdentifier(10,20));
}

是否可以包装此代码，所以我将只发送操作让我们说 _sitesManagement 它将在所有站点上运行此操作？

Answer 1

试试这个:

void PerformOperationOnAllSites(Action<SiteOperation> doIt) {
    foreach (Sites site in _sitesManagement.GetAll()) {
        SiteOperation siteOperation = new SiteOperation(site);
        doIt(siteOperation);
    }
}

...

_sitesManagement.PerformOperationOnAllSites(op => op.LimitBandwidth(wantedBandwidthInLBps));
_sitesManagement.PerformOperationOnAllSites(op => op.KillJames());
_sitesManagement.PerformOperationOnAllSites(op => op.FlyToMoon(2012, new TaskIdentifier(10,20));
