我正在尝试使用SVG图像在自适应卡中显示图像,但未呈现。我的配置如下

{
    "type": "Image",
    "url":  "MY_SVG_IMAGE_URL_PATH",
    "size": "small"
}

但是它没有在屏幕(网络频道)上呈现

我怀疑您提供了无效/不受支持的SVG图片网址,导致该图片无法在网络聊天频道中阅读。

要在自适应卡中显示SVG图像,可以参考以下对我有用的示例代码。

AdaptiveCard card = new AdaptiveCard();

card.Body.Add(new AdaptiveTextBlock()
{
    Text = "Show SVG Images",
    Size = AdaptiveTextSize.Large,
    Weight = AdaptiveTextWeight.Bolder
});

//use the entire SVG syntax
card.Body.Add(new AdaptiveImage()
{
    Type = "Image",
    UrlString = "data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' version='1.1' width='100' height='100'><circle cx='50' cy='50' r='40' stroke='green' stroke-width='4' fill='yellow' />Sorry, your browser does not support inline SVG.</svg>",
    Size = AdaptiveImageSize.Small
});

//convert SVG into Base64 encoding
card.Body.Add(new AdaptiveImage()
{
    Type = "Image",
    UrlString = "data:image/svg+xml;base64,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",

// return our reply to the user
await context.PostAsync(replymes);
