Comma separated output
Hi,

The code below almost work but I need it to separate the output with a comma like this:

/media/1005/test_image_645_1.jpg , /media/1006/test_image_645_2.jpg

At the moment the output is without a comma like this:

/media/1005/test_image_645_1.jpg /media/1006/test_image_645_2.jpg
```
@if (childPage.HasValue("portfolioImages"))
{
  var caseStudyImagesList = childPage.portfolioImages.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
  var caseStudyImagesCollection = Umbraco.Media(caseStudyImagesList);

    foreach (var caseStudyImage in caseStudyImagesCollection)
    {
   @caseStudyImage.Url
 }
}
```
Does anyone have a simple solution?

Thanks in advance!

Hi Rene,

With this code you should be good. :-)

@if (childPage.HasValue("portfolioImages"))
{
    var caseStudyImagesList = childPage.portfolioImages.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
    var caseStudyImagesCollection = Umbraco.Media(caseStudyImagesList);
    
    foreach (var caseStudyImage in caseStudyImagesCollection)
    {
       
        if(caseStudyImage.IsLast()){
             @caseStudyImage.Url
        }else{ 
           @caseStudyImage.Url@:,
        }
            
    }
        
}

Hope this helps,

/Dennis

Hi René,

You could try something like the following. It loops through each of the case study images, combining their urls together and then trimming the end comma:

@if (childPage.HasValue("portfolioImages"))
{
    var caseStudyImagesList = childPage.portfolioImages.Split(new [] { "," }, StringSplitOptions.RemoveEmptyEntries);
    var caseStudyImagesCollection = Umbraco.Media(caseStudyImagesList);

    var outputStr = string.Empty;

    foreach (var caseStudyImage in caseStudyImagesCollection)
    {
        outputStr += string.Format(" , {0}", caseStudyImage.Url);
    }

    @outputStr.TrimEnd(" , ")
}

Hope that helps.

Thanks, Dan.

Hi Dan

I just found one little problem regarding your solution. Because the output is beginning with a comma like below:
```
,/media/1005/test_image_645_1.jpg,/media/1006/test_image_645_2.jpg
```
Is it possible to remove the comma in the beginning?

Thanks!

Ah of course. Trying changing your code to use the following line instead of TrimEnd():
```
@outputStr.TrimStart(",")
```
Thanks, Dan.
