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,
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.

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" />

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));
