Question

使用Fluent Validation C＃库，我有这段代码，当用户创建新的银行帐户时，该代码当前检查余额。

public class BankAccountValidator : AbstractValidator<BankAccount>
{
    private AppDbContext db = new AppDbContext();

    public BankAccountValidator()
    {

        RuleFor(x => x.Balance).GreaterThanOrEqualTo(50).WithMessage($"A minimum of $100.00 balance is required to open Saving bank account type.");


    }

}

但是，现在我为AccountType添加了一个枚举：SavingAccount和CurrentAccount。规则是，储蓄帐户至少需要$ 100.00，而活期帐户至少需要$ 300.00。如何使用Fluent验证库为该检查创建自定义方法？

您应该使用When方法：

When(x => x.AccountType == AccountType.SavingAccount, 
    () => RuleFor(x => x.Balance)
            .GreaterThanOrEqualTo(100)
            .WithMessage($"A minimum of $100.00 balance is required to open Saving bank account type."));

When(x => x.AccountType == AccountType.CurrentAccount,
    () => RuleFor(x => x.Balance)
            .GreaterThanOrEqualTo(300)
            .WithMessage($"A minimum of $300.00 balance is required to open Current bank account type."));
