c# - 在循环中嵌套条件

Question

给定以下代码，是否有更好的方法来构造它？

foreach(Thing item in SomeRandomList)
{
    bool firstCondition = CalculateBool(item, someValue);
    bool secondCondition = CalculateBool(item, someOtherValue);

    //General things are done...
    if(firstCondition || secondCondition)
    {
        //semi-specific things are done...
        if(firstCondition)
        {
            //specific things are done...
        } 
        else
        {
            //specific things are done...
        }
    }
}

此外，如果有更多条件，即 3:

foreach(Thing item in SomeRandomList)
{
    bool firstCondition = CalculateBool(item, someValue);
    bool secondCondition = CalculateBool(item, someOtherValue);
    //imagine as many more as you want.
    bool nthCondition = CalculateBool(item, lastOtherValue);

    //General things are done...
    if(firstCondition || secondCondition || nthCondition)
    {
        //semi-specific things are done...
        if(firstCondition)
        {
            //specific things are done...
        } 
        else if(secondCondition)
        {
            //specific things are done...
        }
        else
        { 
            //specific things are done...
        }
    }
}

Answer 1

是的:多态性。

从公共(public)基础派生Thing(或定义所有Thing 实现的接口(interface))

否则，将条件测试代码移动到 Thing 上的方法中。
