Question

我在ViewModel中有集合，在集合中我有属性Name和Color。我需要将color属性绑定到模板fill.x：key =“model”是为ViewModel

在C＃中：

public class Model
{
public string Name;
public Color Color;
}

public ViewModel
{
 public ObservableCollection<Model> Models { get; set; }
        public MapViewModel()
        {
            this.Models = new ObservableCollection<Model>();
            this.Models.Add(new Model() { Name = "Prabhu",Color = Colors.Red });
            this.Models.Add(new Model() { Name = "raji",Color = Colors.Green });
            this.Models.Add(new Model() { Name = "Pranov",Color = Colors.Black });
        }

}

在XAML中：

         <DataTemplate>
           <Path   Data="F1M1433.97,-17.992L1401.97,-49.992 1433.97,-81.992 1465.97,-49.992 1433.97,-17.992z"  Fill="{Binding Data.model }/>
         </DataTemplate>

是否需要使用转换器？

Answer 1

Fill属性的类型为Brush，而不是Color。您想要的是将Model.Color属性类型更改为Brush或指定SolidColorBrush：

<Path ...>
    <Path.Fill>
        <SolidColorBrush Color="{Binding Color}"/>
    </Path.Fill>
</Path>

还要确保使用属性，而不是字段：

public class Model
{
    public string Name { get; set; }
    public Color Color { get; set; }
}

Answer 2

<Path   Data="F1M1433.97,-17.992L1401.97,-49.992 1433.97,-81.992 1465.97,-49.992 1433.97,-17.992z"  Fill="{Binding Data.Color }/>

当Color绑定到Fill

时，它可以正常工作
