ISerializable.GetObjectData（SerializationInfo，StreamingContext）

Question

我在網上查找關於如何使用此接口的StreamingContext參數的實際示例，但我沒有找到任何東西。即使是關於MS Site的文檔也只是順便提及它。有人可以演示如何以及何時使用它？

Answer 1

它在BCL中被內部使用，實際上並不需要這個StreamingContext，因爲實現是隱藏的。您可以拆卸BCL組件尋找到的StreamingContext（ildsam mscorlib.dll中）的StreamingContext的使用（它是作爲一個構造函數參數）的

例子：

.method assembly hidebysig instance void 
      CompleteSerialization(object serializedObject, 
           class System.Runtime.Serialization.SerializationInfo info, 
           valuetype System.Runtime.Serialization.StreamingContext context) cil managed 
    { 
    .custom instance void System.Security.SecurityCriticalAttribute::.ctor() = (01 00 00 00)
