若要将转换 PointF 为 Point ，请使用 Point.Round 或 Point.Truncate 。To convert a PointF to a Point, use Point.Round or Point.Truncate.

用指定坐标初始化 PointF 类的新实例。Initializes a new instance of the PointF class with the specified coordinates.

Empty

表示 PointF 类的、成员数据未被初始化的新实例。Represents a new instance of the PointF class with member data left uninitialized.

IsEmpty	获取一个值，该值指示此 PointF 是否为空。Gets a value indicating whether this PointF is empty.
X	获取或设置此 PointF 的 x 坐标。Gets or sets the x-coordinate of this PointF.
Y	获取或设置此 PointF 的 y 坐标。Gets or sets the y-coordinate of this PointF.

Add(PointF, Size)	按指定的 PointF 平移给定的 Size。Translates a given PointF by the specified Size.
Add(PointF, SizeF)	按指定的 PointF 平移给定的 SizeF。Translates a given PointF by a specified SizeF.
Equals(Object)	指定此 PointF 是否包含与指定 Object 有相同的坐标。Specifies whether this PointF contains the same coordinates as the specified Object.
Equals(PointF)	指示当前对象是否等于同一类型的另一个对象。Indicates whether the current object is equal to another object of the same type.
GetHashCode()	返回此 PointF 结构的哈希代码。Returns a hash code for this PointF structure.
Subtract(PointF, Size)	按指定大小的负值平移 PointF。Translates a PointF by the negative of a specified size.
Subtract(PointF, SizeF)	按指定大小的负值平移 PointF。Translates a PointF by the negative of a specified size.
