更新：2007 年 11 月

将一个 Shape 对象数组添加到 ShapeCollection。

命名空间： Microsoft.VisualBasic.PowerPacks
程序集： Microsoft.VisualBasic.PowerPacks.Vs（在 Microsoft.VisualBasic.PowerPacks.Vs.dll 中）

语法

声明
Public Sub AddRange ( _
    shapes As Shape() _
)
用法
Dim instance As ShapeCollection
Dim shapes As Shape()

instance.AddRange(shapes)

public void AddRange(
    Shape[] shapes
)

public:
void AddRange(
    array<Shape^>^ shapes
)

public function AddRange(
    shapes : Shape[]
)

参数

shapes
类型：array<Microsoft.VisualBasic.PowerPacks.Shape[]

要添加到集合的 Shape 对象数组。

备注

shapes 数组中包含的 Shape 对象将添加到集合的末尾。

您可以使用 AddRange 方法将一组 Shape 对象快速添加到集合中。这比使用 Add 方法将每个 Shape 手动添加到集合中要快。

若要移除以前添加的 Shape，请使用 Remove、RemoveAt 或 Clear 方法。

对继承者的说明：

在派生类中重写 AddRange 时，一定要调用基类的 AddRange 方法，以保证将形状添加到集合中。

示例

下面的示例将一组 OvalShape 控件添加到窗体的 ShapeCollection。此示例要求窗体上有一个 RectangleShape 控件。

Private Sub RectangleShape1_Click(ByVal sender As System.Object, _
 ByVal e As System.EventArgs) Handles RectangleShape1.Click
    ' Create two oval shapes to add to the form.
    Dim oval1 As OvalShape = New OvalShape()
    Dim oval2 As OvalShape = New OvalShape()

    ' Set the size of the ovals.
    oval1.Size = New Size(100, 200)
    oval2.Size = oval1.Size

    ' Set the appropriate location of ovals.
    oval1.Location = New Point(10, 10)
    oval2.Location = New Point(oval1.Left + 10, oval1.Top + 10)

    ' Add the controls to the form by using the AddRange method.
    RectangleShape1.Parent.Shapes.AddRange(New Shape() {oval1, oval2})
End Sub

private void rectangleShape1_Click(System.Object sender, System.EventArgs e)
{
    // Create two oval shapes to add to the form.
    OvalShape oval1 = new OvalShape();
    OvalShape oval2 = new OvalShape();

    // Set the size of the ovals.
    oval1.Size = new Size(100, 200);
    oval2.Size = oval1.Size;

    // Set the appropriate location of ovals.
    oval1.Location = new Point(10, 10);
    oval2.Location = new Point(oval1.Left + 10, oval1.Top + 10);

    // Add the controls to the form by using the AddRange method.
    rectangleShape1.Parent.Shapes.AddRange(new Shape[] { oval1, oval2 });
}
