1.根据时间对数组对象排序

package main import (     "fmt"     "time"     "github.com/ahmetb/go-linq/v3" ) type CustomTime time.Time
func (a CustomTime) CompareTo(c linq.Comparable) int {     aa := time.Time(a)     bb := time.Time(c.(CustomTime))     if aa.After(bb) {         return 1     } else if aa.Equal(bb) {         return 0     } else {         return -1     } }
type StudyTrainParams struct {     Loss string     Optimizer string     Epochs string     BatchSize string     OperationHours string     FileName string     FullPath string     Accuracy string     UserId int } //对时间进行排序 var orderedList []StudyTrainParams linq.From(res).OrderByDescending(func(i interface{}) interface{} { return common.CustomTime(i.(StudyTrainParams).CreatedAt) }).ToSlice(&orderedList)

2.根据float64类型的数据，对数组对象排序

type CpuList struct {     Username string `json:"username"`     Memory float64 `json:"memory"` } // RandomFloat64 Random 根据区间产生随机数 Float64 func RandomFloat64(min, max float64,send int) float64 {     rand.Seed(int64(send+time.Now().Day()))     return min + rand.Float64() * (max - min) } var cpuList []CpuList for i := 0; i < 10; i++ {     tempcpu:=CpuList{         Username:value.Name,         Memory:RandomFloat64(100,1000,55555),     }     cpuList= append(cpuList, tempcpu) }
sort.Slice(cpuList, func(i, j int) bool { return cpuList[i].Memory > cpuList[j].Memory })

3. 对纯float类型的数组做排序

var cpuList []string{1.11,1.25,0.12,3.65,1.15}
sort.Sort(sort.Reverse(sort.Float64Slice(cpuList)))  //对float64数据进行从大到小排序
