How to link the first image file in a directory

Question

User-1327394822 posted

I have a product page, where I display the product image  by referring the image located in a folder called "Images/Products/1212"..

This folder has several images like Image1.jpg, Image2.jpg, Image3.png

for each product, I would to show the first image. I am using the below code,

@{
    var productFolderContents = new DirectoryInfo(Server.MapPath("~/Images/Products/" + product.Sku + "/Thumb"));
  }
<img src="~/Images/Products/@product.Sku/Thumb/@productFolderContents.GetFiles()[0]" class="img-responsive" alt="@product.Name" />

The above code works...

Can I shorten the above code or is there any efficient way? I feel the above is not so efficient

Hi Gautam,

Maybe instead of getting all the files and looking at the [0] item, if your images have some meaningful name such as productname_1 etc or image1 etc, why not just directly use the image name with you products location in your src.

or this one is better

@{
   var imagePath = Server.MapPath("~/Images/Products/" + product.Sku + "/Thumb");
   var imageName = Path.GetFileName(Directory.GetFiles(imagePath)[0]);
  }
<img src="~/Images/Products/@product.Sku/Thumb/@imageName" class="img-responsive" alt="@product.Name" />

Hi Gautam,

I guess it should be fine as long as your folder is not having tons of files. In anycase, I believe the GetFiles() method must be pretty much optimized for you to see any performance hit.

Try this 

The following will do the trick if you want one file.
using System.IO; 
using System.Linq

var file = Directory.GetFiles("C:\\First\\Second\\").FirstOrDefault();

if (file != null)
{
    var fileName = Path.GetFileName(file);
}
The following will get you all the file names:
using System.IO; 
using System.Linq

var files = Directory.GetFiles("C:\\First\\Second\\");
var fileNames = files.Select(f => Path.GetFileName(f));
