구문

‘선언

Dim id As Guid
Dim returnValue As Boolean

returnValue = instance.Contains(id)

public bool Contains(
    Guid id
)

public:
bool Contains(
    Guid id
)

public boolean Contains(
    Guid id

public function Contains(
    id : Guid
) : boolean

매개 변수

id
형식: System.Guid
확인할 ExtendedProperty 개체의 GUID(Globally Unique Identifier)입니다.

반환 값

형식: System.Boolean
ExtendedProperties 컬렉션에 특정 ExtendedProperty 개체가 포함되어 있으면 true이고, 그렇지 않으면 false입니다.

예제

이 예제에서는 Strokes 컬렉션의 각 Stroke 개체를 검사합니다. Stroke의 ExtendedProperties에 특수 타임스탬프 GUID 개체와 연결된 속성이 포함되어 있는 경우 ExtendedProperty가 컬렉션에서 제거됩니다.

Private Sub RemoveAllTimeStampProperties()
    ' STROKE_START_GUID and STROKE_END_GUID
    ' are class level string const set via GUID generator
    Dim strokeStartGuid As Guid = New Guid(STROKE_START_GUID)
    Dim strokeEndGuid As Guid = New Guid(STROKE_END_GUID)

    ' access the Strokes property via using statement
    ' to insure that the object mStrokes is disposed when finished
    ' Otherwise, you will have a memory leak
    Using mStrokes As Strokes = mInkObject.Ink.Strokes
        For Each S As Stroke In mStrokes
            If S.ExtendedProperties.Contains(strokeStartGuid) Then
                S.ExtendedProperties.Remove(strokeStartGuid)
            End If
            If S.ExtendedProperties.Contains(strokeEndGuid) Then
                S.ExtendedProperties.Remove(strokeEndGuid)
            End If
        Next
    End Using
End Sub

private void RemoveAllTimeStampProperties()
{
    // STROKE_START_GUID and STROKE_END_GUID
    // are class level string const set via GUID generator
    Guid strokeStartGuid = new Guid(STROKE_START_GUID);
    Guid strokeEndGuid = new Guid(STROKE_END_GUID);

    // access the Strokes property via using statement

    // Otherwise, you will have a memory leak
    using (Strokes mStrokes = mInkObject.Ink.Strokes)
    {
        foreach (Stroke S in mStrokes)
        {
            if (S.ExtendedProperties.Contains(strokeStartGuid))
            {
                S.ExtendedProperties.Remove(strokeStartGuid);
            }
            if (S.ExtendedProperties.Contains(strokeEndGuid))
            {
                S.ExtendedProperties.Remove(strokeEndGuid);
