Rect.Width 속성

정의

네임스페이스:

System.Windows

어셈블리:

WindowsBase.dll

사각형의 너비를 가져오거나 설정합니다.

public:
 property double Width { double get(); void set(double value); };

public double Width { get; set; }

member this.Width : double with get, set

Public Property Width As Double

속성 값

Double

사각형의 너비를 나타내는 양수입니다. 기본값은 0입니다.

예외

ArgumentException

Width가 음수 값으로 설정된 경우

InvalidOperationException

Width는 Empty 사각형에 설정됩니다.
