Question

我在集装箱的开端和后来制造了具有进口财产的物体。当我试图使用该财产时,该财产就属于纽尔。

How does MEF handle objects created later on. I refuse to believe you have to instantiate all objects at startup.

Answer 1

当你创建集装箱时,你就不必制造这样的情况,这对任何人都没有任何真正的帮助。你如何制造你的事例? 以下是一些例子:

[Export]
public class MyClass
{
    [Import]
    public MyOtherClass OtherClass { get; set; }
}

我可以:

var myClass = container.GetExportedValue<MyClass>(); // This would automatically compose.

var myExport = container.GetExport<MyClass>();
var myClass = myExport.Value; // This would automatically compose.

var myClass = new MyClass();
container.SatisfyImportsOnce(myClass); // Manually compose your part.

或人工风能,全方使用<条码>CompositionBatch等。
