Go的 switch 非常灵活，表达式不必是常量或整数，执行的过程从上至下，直到找到匹配项，不要break；

var score ＝98var result stringswitch score/10 {　　case 9,10:result="优秀"　　case 8:result="良好"　　case 6,7:result="及格"　　default:result="不及格"}

switch 后面的表达式甚至不是必需的　　

var score ＝-1var result stringswitch  {　　case score<0:result="负数"　　case score＝0:result="零"　　case score>0:result="正数"　　}

　　利子：

package mainimport (	"log"	)import (	"github.com/lxn/walk"	. "github.com/lxn/walk/declarative")var le *walk.LineEditvar sport,maths,english *walk.RadioButtonfunc main() {	if _, err := MainWindow1.Run(); err != nil {		log.Fatal(err)	}	log.Fatal(Bind("enabledCB.Checked"))}var MainWindow1=MainWindow{  Title:   "MainWindow",  MinSize: Size{300, 200},  Layout:  VBox{},     Children: widget,}var widget=[]Widget{  LineEdit1,  RadioButtonSport,   RadioButtonMaths,  RadioButtonEnglish,  PushButtonOK,}var LineEdit1=LineEdit{    AssignTo: &le,}var RadioButtonSport=RadioButton{  AssignTo: &sport,  Text:    "体育系",  }var RadioButtonMaths=RadioButton{  AssignTo: &maths,  Text:    "数学系", }var RadioButtonEnglish=RadioButton{  AssignTo: &english,  Text:    "英语系", }var PushButtonOK=PushButton{  Text: "OK",  OnClicked:OK_Clicked,}func OK_Clicked(){    switch {    case english.Checked():      le.SetText("英语系")    case sport.Checked():      le.SetText("体育系")    case maths.Checked():      le.SetText("数学系")  }}

　　

RadioButton为单选按钮，可以分组，
