针对WCF的企业库6验证:自定义Validator错误消息

Question

我正在WCF中使用Enterprise 6验证。我已经做了一个定制的Validator。当我使用它时，我指定了一个MessageTemplate。当发生错误时，它不是显示MessageTemplate，而是显示自定义验证器的DoValidate中给出的消息。

自定义Validator

public sealed class EmailValidatorAttribute : ValidatorAttribute
{
    protected override Validator DoCreateValidator(Type targetType)
    {
        return new EmailValidator();
    }
}

public sealed class EmailValidator : Validator
{
    public EmailValidator()
        : base("Email Validation", "String")
    {
    }
    protected override string DefaultMessageTemplate
    {
        get { return "Email Validation"; }
    }
    // This method does the actual validation
    public override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults validationResults)
    {
        Regex emailRegex = new Regex(IConnect.DataContract.WCFServiceResources.EmailRegex);
        Match match = emailRegex.Match((string)objectToValidate);
        if (!match.Success)
        {
            LogValidationResult(validationResults, "Invalid Email Address.", currentTarget, key);
        }
    }
}

WCF

[OperationContract]
[FaultContract(typeof(ValidationFault))]
string EmailAddressCheck([EmailValidator(MessageTemplate = "Enter a Valid Email ID.")]string email);

目前，它正在显示“无效电子邮件地址”。自定义Validator代码的DoValidate中定义的。

但

我想向MessageTemplate 显示“输入有效的电子邮件ID”，是在WCF代码中定义的

如何做到这一点？

Answer 1

最后我找到了我的问题的答案。

public override void DoValidate(
    object objectToValidate,
    object currentTarget,
    string key,
    ValidationResults validationResults)
{
    Regex emailRegex = new Regex(IConnect.DataContract.WCFServiceResources.EmailRegex);
    Match match = emailRegex.Match((string)objectToValidate);
    if (!match.Success)
    {
        LogValidationResult(
           validationResults,
           // The next line does the trick
           string.Format(this.MessageTemplate, new object[] { objectToValidate }),
           currentTarget,
           key);
    }
}

在LogValidationResult中发挥作用的部分是：

string.Format(this.MessageTemplate, new object[] { objectToValidate })
