WinRT XAML 工具包中的饼图答案

【问题标题】：PieChart in WinRT XAML ToolkitWinRT XAML 工具包中的饼图
【发布时间】：2015-07-20 10:04:08
【问题描述】：

我正在编写一个 Windows Phone 应用程序 (WinRT 8.1)。

我从 WinRT XAML Toolkit 添加了一个饼图，其中包含 6 个项目。默认的饼图只有 3 种颜色。因此，我在其中添加了 6 ResourceDictionaries。此 PieChart 的索引是 6 种颜色，但 PieChart 仍然显示为 3 种颜色。

C#：

List<Tuple<string, int>> QuestionList = new List<Tuple<string, int>>()
{
    new Tuple<string, int>(Str1, v1),
    new Tuple<string, int>(Str2, v2)

};

Question.Title = "Pie Chart";
(Question.Series[0] as PieSeries).ItemsSource = QuestionList;

【解决方案1】：

重建项目。从移动设备中删除测试应用。 重新安装应用。

【讨论】：

您的意思是说重建（+其他步骤）解决了问题吗？我已经看到 C++/XAML 项目在重新编译其 XAML 时遇到问题，而后面的代码没有任何变化，但您似乎正在使用 C#。您使用的是哪个 Visual Studio 版本？你是用 Nuget 来抓取工具包的吗？
