Type.IsSerializable 属性
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。
注意
Formatter-based serialization is obsolete and should not be used.
获取一个值， Type 该值指示 是否可序列化二进制。

true
Type如果 是二进制可序列化的，则为 ;否则为 false。
- 属性
以下示例创建 类的MyTestClass实例，设置 [Serializable] 属性，并检查 IsSerializable 或 false的属性true。
using namespace System;
public ref class MyClass
{
public:
// Declare a public class with the [Serializable] attribute.
[Serializable]
ref class MyTestClass{};
};
int main()
{
try
{
bool myBool = false;
MyClass::MyTestClass^ myTestClassInstance = gcnew MyClass::MyTestClass;
// Get the type of myTestClassInstance.
Type^ myType = myTestClassInstance->GetType();
// Get the IsSerializable property of myTestClassInstance.
myBool = myType->IsSerializable;
Console::WriteLine( "\nIs {0} serializable? {1}.", myType->FullName, myBool );
}
catch ( Exception^ e )
{
Console::WriteLine( "\nAn exception occurred: {0}", e->Message );
}
}
C#
using System;
namespace SystemType
{
public class MyClass
{
// Declare a public class with the [Serializable] attribute.
[Serializable] public class MyTestClass
{
}
public static void Main(string []args)

try

bool myBool = false;
MyTestClass myTestClassInstance = new MyTestClass();
// Get the type of myTestClassInstance.
Type myType = myTestClassInstance.GetType();
// Get the IsSerializable property of myTestClassInstance.
myBool = myType.IsSerializable;
Console.WriteLine("\nIs {0} serializable? {1}.", myType.FullName, myBool.ToString());
}
catch (Exception e)
{
Console.WriteLine("\nAn exception occurred: {0}", e.Message);
}
}
}
}
open System

type MyTestClass() = class end

.NET Standard 中定义的类型未标记为 SerializableAttribute。 相反，每个 .NET 实现都会确定类型是否是二进制可序列化的。 在运行时，可以使用 IsSerializable 属性来确定该实现是否支持类型的实例的二进制序列化。 有关详细信息和示例，请参阅 如何确定 .NET Standard 对象是否可序列化。
如果当前 Type 表示构造的泛型类型，则此属性适用于从中构造该类型的泛型类型定义。 例如，如果当前 Type 表示 MyGenericType<int> Visual Basic) MyGenericType(Of Integer) 中的 (，则此属性的值由 MyGenericType<T>确定。
如果当前 Type 表示泛型类型或泛型方法的定义中的类型参数，则此属性始终返回 false。
