Type.IsSerializable 属性

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Type.Helpers.cs

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Formatter-based serialization is obsolete and should not be used.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。

public:
 virtual property bool IsSerializable { bool get(); };

[System.Obsolete("Formatter-based serialization is obsolete and should not be used.", DiagnosticId="SYSLIB0050", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public virtual bool IsSerializable { get; }

[<System.Obsolete("Formatter-based serialization is obsolete and should not be used.", DiagnosticId="SYSLIB0050", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
member this.IsSerializable : bool

Public Overridable ReadOnly Property IsSerializable As Boolean

属性值

Boolean

trueType如果 是二进制可序列化的，则为 ;否则为 false。

属性

ObsoleteAttribute

示例

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 );
   }

}

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);
            }
        }
    }
}

                myBool = myType.IsSerializable
                Console.WriteLine(ControlChars.Cr + "Is {0} serializable? {1}.", myType.FullName, myBool.ToString())
            Catch e As Exception
                Console.WriteLine(ControlChars.Cr + "An exception occurred: {0}", e.Message.ToString())
            End Try

注解

.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。
