Remarks

The following example shows how to create and manipulate validation errors as part of a custom validation routine.

This code example is part of the Send Mail SDK Sample and is from the SendEMailActivity.cs file. For more information, see Send Mail Activity.

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
