정의

컬렉션에 컴파일 오류를 나타내는 ValidationError 개체가 포함되어 있는지 여부를 나타냅니다.Indicates whether the collection contains ValidationError objects that indicate compilation errors.

public:
 property bool HasErrors { bool get(); };
public bool HasErrors { get; }
member this.HasErrors : bool
Public ReadOnly Property HasErrors As Boolean

속성 값

활동에서 유효성 검사 오류를 생성했으면 true이고, 그렇지 않으면 false입니다.true if the activity has generated validation errors; otherwise, false.

예제

다음 예제에서는 사용자 지정 유효성 검사 과정의 일환으로 유효성 검사 오류 컬렉션을 만들고 조작하는 방법을 보여 줍니다.The following example shows how to create and manipulate a validation error collection as part of a custom validation routine.

이 코드 예제에서는 보낼 전자 메일 SDK 샘플의 일부 이며 SendMailActivity.cs 파일에 있습니다.This code example is part of the Send Email SDK sample and is from the SendMailActivity.cs file. 자세한 내용은 Send Mail Activity합니다.For more information, see Send Mail Activity.

public class SendEmailValidator : System.Workflow.ComponentModel.Compiler.ActivityValidator
{
    // Define private constants for the Validation Errors 
    private const int InvalidToAddress = 1;
    private const int InvalidFromAddress = 2;
    private const int InvalidSMTPPort = 3;

    //customizing the default activity validation
    public override ValidationErrorCollection ValidateProperties(ValidationManager manager, object obj)
    {

        // Create a new collection for storing the validation errors
        ValidationErrorCollection validationErrors = base.ValidateProperties(manager, obj);


        SendEmailActivity activity = obj as SendEmailActivity;
        if (activity != null)
        {
            // Validate the Email and SMTP Properties
            this.ValidateEmailProperties(validationErrors, activity);
            this.ValidateSMTPProperties(validationErrors, activity);
        }
        return validationErrors;

설명

Activity가 경고를 생성한 경우 해당 경고는 이 속성의 컨텍스트에서 오류로 간주됩니다.If an Activity has generated a warning, the warning is considered an error in the context of this property.
