我需要选择json文件.

public void LoadChartData()
{
   var ofDialog = new System.Windows.Forms.OpenFileDialog { Filter = @"json (*.json)|*.json" };
   if (ofDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
   { }
}

不幸的是,编译此代码会返回错误(每次两次System.Windows.Forms):

Error   CS0234  The type or namespace name 'Forms' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)    

如何处理这个错误？

我需要绑定颜色来填充矩形.

XAML:

<Rectangle Fill="{Binding Colorr}"
           VerticalAlignment="Center"
           Height="3" Width="16"
           Margin="3, 1, 5, 0" 
           Visibility="Visible"/>

视图模型:

public ItemViewModel()
{
     Colorr = Colors.Red;;
}
public Color Colorr
{
    get {
        return color; }
    set
    {
        color = value;
        NotifyOfPropertyChange(() => Colorr);
    }
}

生成的矩形不可见(或透明 - 很难说......),而不是可见和红色.我该怎样摆脱这个问题？
