How Can I Call a Go Struct Method by Its Name Using Reflection?

Invoking Struct Methods by Name in Go

The query pertains to calling a method on a Go struct by specifying its name. Unlike the provided MethodByName() function, the OP envisions a more direct approach.

Implementing the Request

To accomplish this, utilize the following steps:

1. Obtain the Struct Value: Use reflect.ValueOf to obtain the value of the struct pointer.
2. Locate the Method by Name: Employ MethodByName() to find the desired method within the struct value.
3. Invoke the Method: Call the discovered method using Call(), passing an empty slice of reflect.Value arguments in this case.

Example Implementation:

package main

import "fmt"
import "reflect"

type MyStruct struct {}

func (p *MyStruct) MyMethod() {
    fmt.Println("My statement")
}

func main() {
    var s MyStruct
    reflect.ValueOf(&s).MethodByName("MyMethod").Call(nil)
}

Output:

My statement

Note: The MethodByName() function accepts a string argument representing the method's name.
