Freezable.CreateInstanceCore 方法

定義

在衍生類別中實作時,建立 Freezable 衍生類別的新執行個體。When implemented in a derived class, creates a new instance of the Freezable derived class.

protected:
 abstract System::Windows::Freezable ^ CreateInstanceCore();
protected abstract System.Windows.Freezable CreateInstanceCore ();
abstract member CreateInstanceCore : unit -> System.Windows.Freezable
Protected MustOverride Function CreateInstanceCore () As Freezable

傳回

新的執行個體。The new instance.

範例

下列範例顯示 CreateInstanceCore的典型執行。The following example shows a typical implementation of CreateInstanceCore.

public class MyFreezable : Freezable
{
    // Typical implementation of CreateInstanceCore
    protected override Freezable CreateInstanceCore()
    {
    
        return new MyFreezable();      
    }

    // ...
    // Other code for the MyFreezableClass.
    // ...

}

Public Class MyFreezable
    Inherits Freezable
    ' Typical implementation of CreateInstanceCore
    Protected Overrides Function CreateInstanceCore() As Freezable

        Return New MyFreezable()
    End Function


    ' ...
    ' Other code for the MyFreezableClass.
    ' ...


End Class

備註

請勿直接呼叫這個方法(除非是在實作用中呼叫 base)。Do not call this method directly (except when calling base in an implementation). 每當建立新的 Freezable 實例時,CreateInstance 方法就會在內部呼叫這個方法。This method is called internally by the CreateInstance method whenever a new instance of the Freezable is created.

給實施者的注意事項

每個 Freezable 衍生的類別都必須執行此方法。Every Freezable derived class must implement this method. 一般的實作為直接呼叫無參數的函式並傳回結果。A typical implementation is to simply call the parameterless constructor and return the result.
