FigureLength 构造函数

定义

命名空间:

System.Windows

程序集:

PresentationFramework.dll

初始化 FigureLength 的新实例。

重载

FigureLength(Double)	用指定的长度像素数初始化 FigureLength 类的一个新实例。
FigureLength(Double, FigureUnitType)	使用指定的 FigureLength 和 Value 初始化 FigureUnitType 类的新实例。

FigureLength(Double)

用指定的长度像素数初始化 FigureLength 类的一个新实例。

public:
 FigureLength(double pixels);

public FigureLength (double pixels);

new System.Windows.FigureLength : double -> System.Windows.FigureLength

Public Sub New (pixels As Double)

参数

pixels

Double

组成长度的独立于设备的像素数（每英寸 96 像素）。

            if (widthValue > 0)
            {
                myFigure.Width = new FigureLength((widthValue - 10), FigureUnitType.Pixel);
            }
        }
    }
}

FigureLength(Double, FigureUnitType)

使用指定的 FigureLength 和 Value 初始化 FigureUnitType 类的新实例。

public:
 FigureLength(double value, System::Windows::FigureUnitType type);

public FigureLength (double value, System.Windows.FigureUnitType type);

new System.Windows.FigureLength : double * System.Windows.FigureUnitType -> System.Windows.FigureLength

Public Sub New (value As Double, type As FigureUnitType)

参数

value

Double

Value 类的 FigureLength。

type

FigureUnitType

Value 类的 FigureUnitType。
