这个东西可以简化吗

Question

type User struct {
    B0          float64
    B1          float64
    B2          float64
    B3          float64
    B4          float64
    B5          float64
}

switch {
    case money_type == 0:
        User.B0 += money
    case money_type == 1:
        User.B1 += money
    case money_type == 2:
        User.B2 += money
    case money_type == 3:
        User.B3 += money
    case money_type == 4:
        User.B4 += money
    case money_type == 5:
        User.B5 += money
