範例
下列範例示範如何將 base-64 編碼的 ISF 字串轉換為 StrokeCollection 。 這假設有一 presenter
個名為 InkPresenter 的 。
// The base-64 encoded string that contains ink data
// in ink serialized format (ISF).
string strokesString =

備註
會將 StrokeCollectionConverter StrokeCollection 轉換為字串,表示 StrokeCollection base-64、編碼的筆跡序列化格式 (ISF) 。 當無法儲存原始位元組資料時,將筆跡資料儲存為 base-64、編碼的 ISF 會很有用,例如在網頁中。
