Значение свойства

Тип: Microsoft.Ink.ExtendedProperties
The collection of application-defined data.

Заметки

Applications can use the ExtendedProperties property to access the custom data that is stored in the Ink object. This custom data is automatically serialized with the object.

Примеры

In this example, the Dirty property is examined. If true, the Ink object of an InkOverlay object is saved to a file in the default InkSerializedFormat (ISF). An ExtendedProperty is added to the Ink object to track the time that the ink was saved.

Try
    If mInkOverlay.Ink.Dirty Then
        ' TIME_GUID is a class level string set via GUID generator
        Dim timeGuid As Guid = New Guid(TIME_GUID)
        mInkOverlay.Ink.ExtendedProperties.Add(timeGuid, DateTime.Now)
        ' FILE_NAME is a class level const
        Using FS As FileStream = New FileStream(FILE_NAME, FileMode.Create)
            Dim isf As Byte() = mInkOverlay.Ink.Save()
            FS.Write(isf, 0, isf.Length)
        End Using
    End If
Catch
    ' handle or rethrow
End Try

try
{
    if (mInkOverlay.Ink.Dirty)
    {
        // TIME_GUID is a class level string set via GUID generator
        Guid timeGuid = new Guid(TIME_GUID);
        mInkOverlay.Ink.ExtendedProperties.Add(timeGuid, DateTime.Now);
        // FILE_NAME is a class level const
        using (FileStream FS = new FileStream(FILE_NAME, FileMode.Create))
        {
            byte[] isf = mInkOverlay.Ink.Save();
            FS.Write(isf, 0, isf.Length);
        }
    }
}
catch 
{
    // handle or rethrow
}
