将结构转换为字符串切片？

Question

I'm trying to write a CSV file using the package encoding/csv. All data I want to write per line is saved in a struct like this:

type record struct {
    Field0 string
    Field1 string
    Field2 string
    Field3 string
}

The csv package has a method called Write that requires a slice of strings.

Is it possible to convert a struct to a slice of strings?

Answer 1

For example,

package main

import (
    "fmt"
)

type record struct {
    Field0 string
    Field1 string
    Field2 string
    Field3 string
}

func main() {
    r := record{"f0", "f1", "f2", "f3"}
    fmt.Printf("%q
", r)
    s := []string{
        r.Field0,
        r.Field1,
        r.Field2,
        r.Field3,
    }
    fmt.Printf("%q
", s)
}

Output:

{"f0" "f1" "f2" "f3"}
["f0" "f1" "f2" "f3"]
