參數

left
型別：System.Int32

top
型別：System.Int32

width
型別：System.Int32
Integer 代表寬度 (以像素為單位) 的RectangleShape。

height
型別：System.Int32
Integer 代表高度 (以像素為單位) 的RectangleShape。

備註

A RectangleShape控制項無法顯示直接在表單或容器的控制項。它必須包含在ShapeContainer物件。您初始化之後RectangleShape，您必須設定其Parent屬性至現有的ShapeContainer或新的執行個體的ShapeContainer。

範例

下列範例會建立ShapeContainer和RectangleShape、將它們加入至表單，並顯示 90 90 像素的方形像素。

Private Sub DrawSquare()
    Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
    ' Declare a RectangleShape and set the location and size.
    Dim rect1 As New Microsoft.VisualBasic.PowerPacks.
        RectangleShape(15, 15, 105, 105)
    ' Set the form as the parent of the ShapeContainer.
    canvas.Parent = Me
    ' Set the ShapeContainer as the parent of the RectangleShape.
    rect1.Parent = canvas
End Sub

private void DrawSquare()
{
    Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas = 
        new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
    // Declare a RectangleShape and set the location and size.
    Microsoft.VisualBasic.PowerPacks.RectangleShape rect1 = 
        new Microsoft.VisualBasic.PowerPacks.RectangleShape(15, 15, 105, 105);
    // Set the form as the parent of the ShapeContainer.
    canvas.Parent = this;
    // Set the ShapeContainer as the parent of the RectangleShape.
    rect1.Parent = canvas;
}
