有其他开关吗？

Question

switch在 PowerShell 中就像一个不太复杂的if elseif语句，但else不起作用。还有什么我可以做的吗？

switch ("test") {
  "1" {"2"}
  "2" {"1"}
} else {"other"}

给出错误

else : The term 'else' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.

开关的 else 是default选项：

switch ("test") {
  "1" {"2"}
  "2" {"1"}
  Default {"other"}
}
