How to link the first image file in a directory RRS feed

  • 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,

    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));
