Question

最近，我一直在使用Antaris RazorEngine为我正在进行的C＃类库做一些电子邮件模板。到目前为止，我可以从模型中获得一般文本显示在视图上。但是当我试图显示一个图像引擎抛出异常时：

类型＆＃39; RazorEngine.Templating.TemplateCompilationException＆＃39;的第一次机会异常发生在RazorEngine.dll

目前我有一个UserModel类，它包含3个属性，这些属性具有字符串数据，另一个属性具有从Resources.resx文件加载的Bitmap图像。我想知道来自Antaris的第三方RazorEngine不支持以位图格式渲染图像吗？我似乎无法找到与此相关的任何详细文档： - （

以下相关代码：
