如何在结构数组中映射文本文件内容？

Question

I have a text file data.txt:

0,0123,"Value 1"
1,0456,"Value 2"

In Go I have defined struct:

type ChangeStatus struct {
  Nr1 string
  Nr2 string
  Category string
}

I am new to Go so I was wondering how can I read that text file and put each text file line into array of ChangeStatus?

You could use csv.Reader for that, for example:

func main() {
    status := []ChangeStatus{}
    f := strings.NewReader(text_file) //replace this with os.Open as needed
    //defer f.Close()
    r := csv.NewReader(f)
    for {
        if parts, err := r.Read(); err == nil {
            cs := ChangeStatus{parts[0], parts[1], parts[2]}
            status = append(status, cs)
        } else {
            break
        }
    }
    fmt.Printf("%+v
", status)
}
