Base64图像不会显示

Question

我正在创建一个Base64 png图像（一个二维码），但它不会显示（MVC项目）。我只是在页面上打印HTML代码。我已经使用在线Base64图像查看器验证了图像是否正确显示。

这是观看代码：

<div class="widget-body">
  <div class="topUpBlock">
  <p style="text-align: left"> Click to create a QR code that can be scanned to buy a meal. </p>

    <a href="@Url.Action("CreateMealStub", "Home", new {cardId = card.CardId})">
            <span class="btn btn-primary pull-right">Generate</span>
        </a>
    </div>     
    @Model.MealStubImage
</div>

Model.MealStub包含以下字符串：

<img src="data:image/png; base64,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...
