示例

以下示例演示如何在自定义验证例程中创建和操作验证错误。

此代码示例是发送邮件 SDK 示例的一部分，来自SendEMailActivity.cs文件。 有关详细信息，请参阅 “发送邮件活动”。

private void ValidateEmailProperties(ValidationErrorCollection validationErrors, SendEmailActivity activity)
{
    // Validate the To property
    if (string.IsNullOrEmpty(activity.To))
    {
        validationErrors.Add(ValidationError.GetNotSetValidationError(SendEmailActivity.ToProperty.Name));
    }
    else if (!activity.To.Contains("@"))
    {
        validationErrors.Add(new ValidationError("Invalid To email address", InvalidToAddress, false, SendEmailActivity.ToProperty.Name));
    }

    // Validate the From property
    if (string.IsNullOrEmpty(activity.From))
    {
        validationErrors.Add(ValidationError.GetNotSetValidationError(SendEmailActivity.FromProperty.Name));
    }
    else if (!activity.From.Contains("@"))
    {
        validationErrors.Add(new ValidationError("Invalid From email address", InvalidFromAddress, false, SendEmailActivity.FromProperty.Name));
    }
}

Private Sub ValidateEmailProperties(ByVal validationErrors As ValidationErrorCollection, ByVal activity As SendEmailActivity)
    'Validate the To property
    If String.IsNullOrEmpty(activity.EmailTo) Then
        Dim validationError As ValidationError = System.Workflow.ComponentModel.Compiler.ValidationError.GetNotSetValidationError(SendEmailActivity.ToProperty.Name)
        validationErrors.Add(validationError)
    ElseIf Not activity.EmailTo.Contains("@") Then
        Dim validationError As New ValidationError("Invalid To email address", _
          InvalidToAddress, False, SendEmailActivity.ToProperty.Name)
        validationErrors.Add(validationError)
    End If

    ' Validate the From property
    If String.IsNullOrEmpty(activity.FromEmail) Then
        validationErrors.Add(ValidationError.GetNotSetValidationError(SendEmailActivity.FromEmailProperty.Name))
    ElseIf Not activity.FromEmail.Contains("@") Then
        Dim validationError As New ValidationError("Invalid From email address", _
            InvalidFromAddress, False, SendEmailActivity.FromEmailProperty.Name)
        validationErrors.Add(validationError)
    End If
End Sub
