Go不能简单的将slice转换为接口的slice

funcmain(){
findAnyMax([]int{2,1,3,5,7,6,4})
}

funcfindAnyMax(i[]interface{})interface{}{
switchi.(type){
casestring：
//...
caseint：
//...
}
return/*...*/
}

运行会失败：cannot use i (type[]int) as type []interface in function argument

修改了一下，实际上通过规避slice的转换同样没有根本性的解决问题，golang中不容许slice的隐式转换。

packagemain

import(
"fmt"
)

funcmain(){
fmt.Println(findAnyMax(Int{2,2,8,100,12,34}))
fmt.Println(findAnyMax(Float{1,4,102,100}))
}

typeInt[]int
typeFloat[]float32

typeMaxinterface{
Len()int
Get(iint)interface{}
}

func(iInt)Len()int{
returnlen(i)
}

func(iInt)Get(idxint)interface{}{
returni[idx]
}

func(iFloat)Len()int{
returnlen(i)
}

func(iFloat)Get(idxint)interface{}{
returni[idx]
}

funcfindAnyMax(lMax)interface{}{
switchl.(type){
caseInt:
max:=l.Get(0)
fori:=1;i<l.Len();i++{
ifl.Get(i).(int)>max.(int){
max=l.Get(i)
}
}
returnmax
caseFloat:
max:=l.Get(0)
fori:=1;i<l.Len();i++{
ifl.Get(i).(float32)>max.(float32){
max=l.Get(i)
}
}
returnmax
default:
fmt.Println("typemiss")
}
returnnil
}

有点费解~~~
