How to get property of struct by name?


I have this struct definition :

// Two columns, both strings.
type ExampleStructItem struct {
    Firstname string
    Surname string
}

and I have this slice of column names :

columns := []string{"Firstname", "Surname"}

and I am essentially trying to loop through my slice of column names, and then perform reflection on the corresponding struct to get information about the properties, such as their "Kind" etc.


Solution

  • Just use Type.FieldByName()

    var ex ExampleStructItem
    t := reflect.TypeOf(ex)
    
    for _, name := range columns {
    
        field, ok := t.FieldByName(name)
        if ok {
            k := field.Type.Kind()
        } else {
            // error handling
        }
    
    }
