向MapControl添加pin时无法隐式转换类型

Question

我试图动态地向MapControl添加一个pin，但尽管使用了import语句(using(，它还是无法工作。NormalizedAnchorPoint = new Point(0.5, 1)中的new Point(0.5, 1)返回以下错误。解决这个问题的正确方法是什么？

无法将类型'Windows.Foundation.Point'隐式转换为'System.Drawing.Point'

问题是NormalizedAnchorPoint属性正在使用System.Drawing命名空间。您可以为NormalizedAnchorPoint添加完整的名称空间Windows.Foundation.Point来指定它的类型，如下所示。

public class PointOfInterest
{
public string PinName { get; set; }
public string DisplayName { get; set; }
public Uri ImageSourceUri { get; set; }
public Windows.Foundation.Point NormalizedAnchorPoint { get; set; }
public Geopoint Location { get; set; }
}
