NativeActivity 建構函式

定義

命名空間:

System.Activities

組件:

System.Activities.dll

當在導出類別中實作時，會建立該衍生類別的新實例。

protected:
 NativeActivity();

protected NativeActivity();

Protected Sub New ()

範例

以下程式碼範例示範如何建立一個繼承自 NativeActivity<TResult>的類別。 這個範例來自 使用 Native Activity 的自訂合成 範例。

public sealed class MySequence : NativeActivity
{
    Collection<Activity> children;
    Collection<Variable> variables;
    Variable<int> currentIndex;
    CompletionCallback onChildComplete;

    public MySequence()
        : base()
    {
        this.children = new Collection<Activity>();
        this.variables = new Collection<Variable>();
        this.currentIndex = new Variable<int>();
    }

    public Collection<Activity> Activities
    {
        get
        {
            return this.children;
        }
    }

    public Collection<Variable> Variables
    {
        get
        {
            return this.variables;
        }
    }
