c# - 有没有办法让比较更短

Question

我怎样才能使它更短？

string veryLongVariableName;

if (veryLongVariableName == "a" || veryLongVariableName == "b" || veryLongVariableName == "c"|| veryLongVariableName == "d"|| veryLongVariableName == "e"|| veryLongVariableName == "f")

这样的事情可能吗？

if (veryLongVariableName == ("a", "b", "c", "d", "e", "f"))
if (veryLongVariableName == ("a" || "b" || "c" || "d" || "e" || "f"))

Answer 1

你几乎拥有它

if (new [] {"a", "b", "c", "d", "e", "f"}.Contains(veryLongVariableName))

_{注意：每次调用时都会分配}
