使用静态或非静态类

永远不要创造静态,除非你真的,真的必须如果你这样做,你将为自己做好准备.你使测试更难,你使线程冲突的可能性(正如你所描述的)发生得更高.

如果必须在类中设置状态然后调用方法,而不是仅将值作为参数传递给方法,请将其设置为非静态类.此外,您最好通过构造函数传递值,而不是使用属性.

话虽如此,我对您的问题的处理方法是创建一个POCO来保存结果数据并使用静态方法进行计算.使用C#6语法,这将看起来像:

public class BreakTimeResult
{
    public BreakTimeResult(int breakFromSec, int breakUntilSec)
    {
        BreakFromSec = breakFromSec;
        BreakUntilSec = breakUntilSec;
    }

    public int BreakFromSec { get; }
    public int BreakUntilSec { get; }
}


public static class BreakTimeCalculator
{
    public static BreakTimeResult CalculateBreakFromAndBreakeUntil(int customBreakSec,
                                                                   int fromSec,
                                                                   int untilSec,
                                                                   int equlizer)
    {
        var taskLength = untilSec - fromSec;
        var middleOfTask = fromSec + (taskLength / 2);
        var secondsToMoveLeft = middleOfTask % 300;
        var amountEqualizers = customBreakSec / equlizer;
        var fiftyFifty = amountEqualizers % 2 == 0;
        var leftSideEqualizers = fiftyFifty 
            ? amountEqualizers / 2 
            : (amountEqualizers / 2) + 1;

        var breakFromSec = middleOfTask - secondsToMoveLeft - (leftSideEqualizers * equlizer);
        var breakUntilSec = breakFromSec + customBreakSec;
        return new BreakTimeResult(breakFromSec, breakUntilSec);
    }
}
