Question

我目前正在使用部分视图，使用Umbraco 7加载Google地图和大量信息。

我要做的是在“infoWindow”（代码的底部功能）Google API弹出窗口（标记弹出信息）中加载项目图像。

我尝试了很多不同的方法，但似乎无法获得图像。我能在不破坏事物的情况下获得的最远的是获取图像ID。我一直无法拆分或输出任何东西。

我尝试了以下内容：

var imagesList = portfolioItem.GetPropertyValue<string>("Images").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
var imagesCollection = Umbraco.TypedMedia(imagesList).Where(x => x != null);

我收到此错误：

Compiler Error Message: CS1976: Cannot use 'Parse' as an argument to a dynamically dispatched operation because it is a method group. Did you intend to invoke the method?

http://prntscr.com/99u5ky

var mediaItem = portfolioItem.GetPropertyValue("images");

这是我用来获取图片ID的行，但每次我尝试拆分它们并输出任何我收到错误的行。

Answer 1

我设法通过使用以下方法解决了这个问题，并且我能够看到所有图像。

var imagesList = portfolioItem.GetPropertyValue<string>("Images").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
var imagesCollection = Umbraco.TypedMedia(imagesList);

foreach (var imageItem in imagesCollection)
{      
    <img src="@imageItem.Url" />
}

Answer 2

除非我遗漏了某些内容，否则失败的代码位于Split行。但是，您要做的就是将逗号分隔的值列表分开，这些值始终是数字而没有任何空项，因此以下内容应该可以在没有您尝试的所有额外工作的情况下工作。

var imageList = portfolioItem.HasValue("Images") ?  portfolioItem.GetPropertyValue<string>("Images").Split(',').ToList() : null;

if(imageList != null)
{
    var imagesCollection = Umbraco.TypedMedia(imageList);
}
