1.用字符串连接切片元素(类似php implode)
package mainimport ("fmt""strconv""strings"
)func main() {data := []int{104, 101, 108, 108, 111}fmt.Println(IntSliceToString(data, ","))
}func IntSliceToString(intSlice []int, sep string) string {strBuilder := new(strings.Builder)for i, intValue := range intSlice {if i > 0 {strBuilder.WriteString(sep)}strBuilder.WriteString(strconv.Itoa(intValue))}return strBuilder.String()
}
运行结果:
