Question

昨天我发布了一个问题，说明为什么我无法显示我的图片。 Cant get the image to show in Umbraco7 with razor

我得到了很好的答案。

问题是，当我使用如何获取图像的示例时，我会收到如下错误：

Line 1:  @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
Line 2:  @{
Line 3:      Layout = "Master.cshtml";
Line 4:  }
Line 5:  <div class="container">

如果我删除它：

 <img src="@Umbraco.Media(CurrentPage.deal1image).Url" />

然后一切都很好，但没有任何图像。

在我的文档类型Home中，我使用了Media Picker作为通用属性。别名是deal1image。它们位于名为Deals的标签下。

希望你们中的一个能帮助我。

这是整个错误：

以下方法或属性之间的调用不明确：'Umbraco.Web.UmbracoHelper.Media（params int []）'和'Umbraco.Web.UmbracoHelper.Media（params string []）'

更新回答：

错误告诉您它不知道使用哪种方法，因为“deal1image”不返回任何内容。所以你必须检查“deal1image”是否有任何价值。像这样：

@if(CurrentPage.HasValue("deal1image"))
{
   <img src="@Umbraco.Media(CurrentPage.deal1image).Url" />
}

您是否1000％确定“deal1image”是您的媒体资源的别名，并且您选择了umbraco中的任何媒体项目？

不会显示图像，而是在我的母版页布局上出错。 Umbraco 7，剃刀
