[Golang] Call a Struct and its Method by Name

Call a function (method) of a struct by name during run-time in Golang. (run-time reflection)

Run Code on Go Playground

package main

import (

type Circle struct {
        r float64

func (c *Circle) Area() float64 {
        return math.Pi * c.r * c.r

func main() {
        c := Circle{1.2}

        // call Area() method

        // call Area() method by Name
        v := reflect.ValueOf(&c).MethodByName("Area").Call([]reflect.Value{})
