呈现卡片 - .NET WPF

下面介绍如何使用 .NET WPF SDK 呈现卡片。

注释

Media 使用 HTTPS URL 在 WPF 中不起作用

由于 WPF MediaElement 控件中的 bug ，我们无法呈现通过 HTTPS 提供的媒体。 应在Media元素中使用HTTP URL，直到该问题得到解决。

实例化呈现器

创建呈现器库的实例。

using AdaptiveCards;
using AdaptiveCards.Rendering;
using AdaptiveCards.Rendering.Wpf;
// ...

// Create a card renderer
AdaptiveCardRenderer renderer = new AdaptiveCardRenderer();

// If using the Xceed package, enable the enhanced input
renderer.UseXceedElementRenderers();

// For fun, check the schema version this renderer supports
AdaptiveSchemaVersion schemaVersion = renderer.SupportedSchemaVersion;

将卡片渲染到 XAML

// Build a simple card
// In the real world this would probably be provided as JSON
AdaptiveCard card = new AdaptiveCard("1.0")
{
    Body = { new AdaptiveTextBlock() { Text = "Hello World" } }
};

try
{
    // Render the card
    RenderedAdaptiveCard renderedCard = renderer.RenderCard(card);

    // Get the FrameworkElement
    // Add this to your app's UI somewhere
    FrameworkElement fe = renderedCard.FrameworkElement;

    // (Optional) Check for any renderer warnings
    // This includes things like an unknown element type found in the card
    // Or the card exceeded the maximum number of supported actions, etc
    IList<AdaptiveWarning> warnings = renderedCard.Warnings;
}
catch(AdaptiveException ex)
{
    // Failed rendering
}
