  • 参考

定义

命名空间:
System.Web.UI.WebControls
程序集:
System.Web.dll

将指定的从 WizardStepBase 派生的对象插入集合中的指定索引位置。

public:
 void Insert(int index, System::Web::UI::WebControls::WizardStepBase ^ wizardStep);
public void Insert (int index, System.Web.UI.WebControls.WizardStepBase wizardStep);
member this.Insert : int * System.Web.UI.WebControls.WizardStepBase -> unit
Public Sub Insert (index As Integer, wizardStep As WizardStepBase)

参数

index
Int32

要插入从 WizardStepBase 派生的对象的索引位置。

wizardStep
WizardStepBase

要插入 WizardStepBase 集合中的从 WizardStepCollection 派生的对象。

示例

下面的代码示例演示如何以编程方式创建控件Wizard，并使用 Insert 方法将 派生对象添加到WizardStepBase集合。WizardSteps 请注意，在示例中， WizardSteps 控件的 Wizard 属性是 类的 WizardStepCollection 实例。

注解

方法 Insert 将 WizardStepBase派生对象添加到集合中的指定索引位置。

或者，可以使用 AddAt 方法将 WizardStepBase派生对象添加到集合。 若要将 WizardStepBase派生对象添加到集合的 WizardStepCollection 末尾，请使用 Add 方法。

注意

方法和 Insert 方法 AddAt 执行基本相同的函数。 Insert调用 方法时，它只需将 wizardStep 和 index 参数传递给 AddAt 方法。
