IDataContractSurrogate.GetDataContractType(Type) 方法
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
在序列化、反序列化以及架构导入和导出期间，返回一个替换指定类型的数据协定类型。
public:
Type ^ GetDataContractType(Type ^ type);public Type GetDataContractType (Type type);abstract member GetDataContractType : Type -> TypePublic Function GetDataContractType (type As Type) As Type参数
返回
替换 Type 值的 type。 此类型必须可由 DataContractSerializer 序列化。 例如，必须用 DataContractAttribute 属性或序列化程序可识别的其他机制对它进行标记。
示例
下面的示例演示 GetDataContractType 方法的实现。
public Type GetDataContractType(Type type)
{
Console.WriteLine("GetDataContractType invoked");
Console.WriteLine("\t type name: {0}", type.Name);
// "Person" will be serialized as "PersonSurrogated"
// This method is called during serialization,
// deserialization, and schema export.
if (typeof(Person).IsAssignableFrom(type))
{
Console.WriteLine("\t returning PersonSurrogated");
return typeof(PersonSurrogated);
}
return type;
}
Public Function GetDataContractType(ByVal type As Type) As Type _
Implements IDataContractSurrogate.GetDataContractType
Console.WriteLine("GetDataContractType invoked")
Console.WriteLine(vbTab & "type name: {0}", type.Name)
' "Person" will be serialized as "PersonSurrogated"
' This method is called during serialization,
' deserialization, and schema export.
If GetType(Person).IsAssignableFrom(type) Then
Console.WriteLine(vbTab & "returning PersonSurrogated")
Return GetType(PersonSurrogated)
End If
Return type
End Function
