通过

WizardStepCollection.Insert(Int32, WizardStepBase) 方法

定义

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

将指定的 WizardStepBase派生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 WizardStepBase-derived 对象的索引位置。

wizardStep
WizardStepBase

要 WizardStepBase插入到集合中的 WizardStepCollection -derived 对象。

示例

下面的代码示例演示如何以编程方式创建 Wizard 控件，并使用 Insert 方法向集合中添加 WizardStepBase派生对象 WizardSteps 。 请注意，在此示例中， WizardSteps 控件的属性 Wizard 是类的 WizardStepCollection 实例。

注解

该方法 Insert 将 WizardStepBase-derived 对象添加到集合中的指定索引位置。

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

注释

该方法 Insert 和 AddAt 方法基本上执行相同的函数。 Insert调用该方法时，只需将wizardStep和index参数传递给AddAt该方法。
