Rect.Width 속성

사각형의 너비를 가져오거나 설정합니다.

네임스페이스:  System.Windows
어셈블리:  WindowsBase(WindowsBase.dll)
XAML의 XMLNS: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

public double Width { get; set; }
<object Width="double" .../>

속성 값

형식: System.Double
사각형의 너비를 나타내는 양수입니다. 기본값은 0입니다.

예외상황
ArgumentException

Width 가 음수 값으로 설정된 경우

InvalidOperationException

Width Empty 사각형에 설정됩니다.

Empty 사각형의 WidthNegativeInfinity입니다. Empty 사각형은 읽기 전용이므로 Width를 변경할 수 없습니다.

다음 예제에서는 Rect 구조체를 사용하여 XAML을 통해 사각형의 크기와 위치를 지정하는 방법을 보여 줍니다.
