问题描述

在if语句单行，在C＃和VB.NET作为存在于以下格式的许多其他编程和脚本语言

The "single line if statement" exists in C# and VB.NET as in many other programming and script languages in the following format

lunchLocation = (dayOfTheWeek == "Tuesday") ? "Fuddruckers" : "Food Court";

没有人知道，如果有，即使在VBScript和什么是extact语法？

does anyone know if there is even in VBScript and what's the extact syntax?

推荐答案

有条件的三元运算符不存在现成的，但它是pretty容易在VBScript中创建自己的版本：

The conditional ternary operator doesn't exist out of the box, but it's pretty easy to create your own version in VBScript:

Function IIf(bClause, sTrue, sFalse)
    If CBool(bClause) Then
        IIf = sTrue
    Else 
        IIf = sFalse
    End If
End Function

然后，您可以使用此功能，根据您的例子：

You can then use this, as per your example:

lunchLocation = IIf(dayOfTheWeek = "Tuesday", "Fuddruckers", "Food Court")

这比使用单行的优点如果 / 然后 / 否则是，它可以与其他字符串被直接连接起来。使用如果 / 然后 / 否则在同一行必须是在该行的嘛。

The advantage of this over using a single line If/Then/Else is that it can be directly concatenated with other strings. Using If/Then/Else on a single line must be the only thing on that line.
