golangIterate through struct ("foreach" style)
package main
import "fmt"
import "reflect"
func main() {
st := struct{name string; age int }{"Joe", 25}
v := reflect.ValueOf(st)
for i := 0; i < v.NumField(); i++ {
fmt.Println(i, v.Field(i))
}
}ctrl + cpackage maindefault package declaration | st :=sample structure |
reflect.ValueOf(st)returns reflection for given structure | for i := 0; i < v.NumField(); i++iterate over all values of structure |
Usage example
package main
import "fmt"
import "reflect"
func main() {
st := struct{name string; age int }{"Joe", 25}
v := reflect.ValueOf(st)
for i := 0; i < v.NumField(); i++ {
fmt.Println(i, v.Field(i))
}
}output
0 Joe
1 25
