F# 中的条件运算符 (A?B:C)
Conditional Operator in F# (A?B:C)
在 C# 中，我们有条件运算符：
[condition] ? [value if true] : [value if false]
但我似乎无法在 F# 中找到它。它存在吗？
据发现here答案是
C# has the ternary operator "?:" for conditional expressions:
condition ? trueVal : falseVal
F# has the same operator, but its name is if-then-else:
if condition then trueVal else falseVal
(Note that "if" is used much less frequently in F# than in C#; in F#, many conditionalexpressions are done via pattern-matching rather than if-then-else.)
