BitmapMetadata.IsReadOnly 屬性

定義

命名空間:
System.Windows.Media.Imaging
組件:
PresentationCore.dll

會獲得一個值，表示與影像相關的元資料是否為唯讀。

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

屬性值

Boolean

true若元資料為唯讀;否則，。 false 預設值為 false。

範例

以下程式碼範例示範如何讀取物件的 BitmapMetadata 各種屬性，並將其值以字串形式傳送給 a MessageBox 。

FileStream stream4 = new FileStream("image3.tif", FileMode.Create);
BitmapMetadata myBitmapMetadata2 = new BitmapMetadata("tiff");
TiffBitmapEncoder encoder4 = new TiffBitmapEncoder();
MessageBox.Show(myBitmapMetadata2.IsFixedSize.ToString());
MessageBox.Show(myBitmapMetadata2.IsReadOnly.ToString());
MessageBox.Show(myBitmapMetadata2.Format.ToString());
MessageBox.Show(myBitmapMetadata2.Location.ToString());
encoder4.Frames = decoder2.Frames;
encoder4.Save(stream4);
stream4.Close();

Dim stream4 As New FileStream("image3.tif", FileMode.Create)
Dim myBitmapMetadata2 As New BitmapMetadata("tiff")
Dim encoder4 As New TiffBitmapEncoder()
MessageBox.Show(myBitmapMetadata2.IsFixedSize.ToString())
MessageBox.Show(myBitmapMetadata2.IsReadOnly.ToString())
MessageBox.Show(myBitmapMetadata2.Format.ToString())
MessageBox.Show(myBitmapMetadata2.Location.ToString())
encoder4.Frames = decoder2.Frames
encoder4.Save(stream4)
stream4.Close()
