一线将[] int转换为字符串

一线将[] int转换为字符串

转换

A := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}

到一行分隔字符串，例如
“ 1,2,3,4,5,6,7,8,9”，请
使用：

strings.Trim(strings.Join(strings.Fields(fmt.Sprint(A)), delim), "[]")

要么：

strings.Trim(strings.Join(strings.Split(fmt.Sprint(A), " "), delim), "[]")

要么：

strings.Trim(strings.Replace(fmt.Sprint(A), " ", delim, -1), "[]")

并从此示例中的函数返回它：

package mainimport "fmt"import "strings"func arrayToString(a []int, delim string) string {    return strings.Trim(strings.Replace(fmt.Sprint(a), " ", delim, -1), "[]")    //return strings.Trim(strings.Join(strings.Split(fmt.Sprint(a), " "), delim), "[]")    //return strings.Trim(strings.Join(strings.Fields(fmt.Sprint(a)), delim), "[]")}func main() {    A := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}    fmt.Println(arrayToString(A, ",")) //1,2,3,4,5,6,7,8,9}

要在逗号后包含空格，您可以调用

arrayToString(A, ", ")

或反过来定义return

returnstrings.Trim(strings.Replace(fmt.Sprint(a), " ", delim + " ", -1),"[]")

以强制将其插入定界符之后。
