Question

提前道歉，不要赛马我的马匹＆＃39;

Haven在任何地方都没有看到这个确切的问题，但只是好奇什么类型的if语句会更有效，或者它是否可以忽略不计，而且只是基于编译器。

if (data[i].Occupied) {
    var color1 = "#E51616";
    var drop1 = "";
    var drag1 = "LocationDrag";
    var work1 = data[i].Works_Order_Number;
} else {
    var color1 = "#008000";
    var drop1 = "tdDrop";
    var drag1 = "";
    var work1 = "";
}
if (data[i + 1].Occupied) {
    var color1 = "#E51616";
    var drop1 = "";
    var drag1 = "LocationDrag";
    var work1 = data[i].Works_Order_Number;
} else {
    var color1 = "#008000";
    var drop1 = "tdDrop";
    var drag1 = "";
    var work1 = "";
}

OR

var color1 = data[i].Occupied ? "#E51616" : "#008000";
var color2 = data[i + 1].Occupied ? "#E51616" : "#008000";
var drop1 = data[i].Occupied ? "" : "tdDrop";
var drop2 = data[i + 1].Occupied ? "" : "tdDrop";
var drag1 = data[i].Occupied ? "LocationDrag" : "";
var drag2 = data[i].Occupied ? "LocationDrag" : "";
var work1 = data[i].Occupied ? data[i].Works_Order_Number : "";
var work2 = data[i + 1].Occupied ? data[i + 1].Works_Order_Number : "";

为什么不测试自己？只需在System Diagnostics命名空间中使用Stopwatch类，看看是否可以找到执行时间的任何差异。

然而，我会非常自信地说你不会发现差异，或者它会如此之小，无关紧要。正如其他人所说，可读性在这里获胜。

if语句的哪些集合会更有效？
