Go Lang-接口和数组

I have a variable that i think is of type "[]interface {}"

  1. How do i detect it
  2. Convert to array ?

Here's the code:

var s string
switch value1 := value1.(type) {
case int:
    s = strconv.Itoa(value1)
case float64:
    s = strconv.FormatFloat(value1, 'f', 0, 64)
//case array:
    //fmt.Printf("array")
default :
    fmt.Printf("
value=v+%",value1)
}

And the output is:

value=v+%!(NOVERB)%!(EXTRA []interface {}=

    You can select for a slice in a type switch the same as other types. For example:

    switch v := value1.(type) {
    case []interface{}:
        for _, element := range v {
            fmt.Println(element)
        }
    } 
    

    You can play with this example here: http://play.golang.org/p/4z9eejp4BL
