将验证从免费的 pdf asp.net mvc nerdinner (c#) 转换为 vb.net

Question

您如何将此代码转换为 vb.net，因为 vb 没有 yield 关键字

谢谢

public IEnumerable<RuleViolation> GetRuleViolations() {
    if (String.IsNullOrEmpty(Title))
        yield return new RuleViolation("Title required", "Title");
    if (String.IsNullOrEmpty(Description))
        yield return new RuleViolation("Description required","Description");
    if (String.IsNullOrEmpty(HostedBy))
        yield return new RuleViolation("HostedBy required", "HostedBy");
    if (String.IsNullOrEmpty(Address))
        yield return new RuleViolation("Address required", "Address");
    if (String.IsNullOrEmpty(Country))
        yield return new RuleViolation("Country required", "Country");
    if (String.IsNullOrEmpty(ContactPhone))
        yield return new RuleViolation("Phone# required", "ContactPhone");
    if (!PhoneValidator.IsValidNumber(ContactPhone, Country))
        yield return new RuleViolation("Phone# does not match country", "ContactPhone");
    yield break;
}

创建一个列表，而不是执行“yield return”，只需将这些规则添加到列表中。然后只需简单地返回列表。
