public void Serialize (System.IO.Stream serializationStream, object graph);
abstract member Serialize : System.IO.Stream * obj -> unit
override this.Serialize : System.IO.Stream * obj -> unit
Public Sub Serialize (serializationStream As Stream, graph As Object)

參數

serializationStream
Stream Stream Stream Stream

要序列化圖形的目的資料流。The stream to which the graph is to be serialized.

graph
Object Object Object Object

物件,位在要序列化的 Graph 的根。The object at the root of the graph to serialize.

實作

例外狀況

serializationStreamnullThe serializationStream is null.

-或--or- graph 為 null。The graph is null.

在序列化期間發生錯誤,例如在 graph 參數中的物件未標記為可序列化。An error has occurred during serialization, such as if an object in the graph parameter is not marked as serializable.

呼叫端沒有必要的使用權限。The caller does not have the required permission.
