I´m working on a personal side project, a web store, as an ASP.Net Core application with C#.
I'm trying to create an ImageHandler service that is to be used for fetching images that are located in a folder in the project.
I´m trying to structure the images so that they are easy to manage in the project with code, and to be easily overseeable, so I created a bunch of subfolders/directories.
The path looks like this:
WebRoot/Images/Articles/ArticleFolder/ArticleImages.jpg
The Article folder is named Article.id_Article.Name so a complete example would be:
\wwwroot\Images\Articles\1_iPhone 13 Pro Max – 5G smartphone 128GB Silver\1_01.jpg.
I'm trying to write a statement that finds the right folder for a given article by making a selection on the first part of the folder name that is equal to the ID of the article it belongs to.
My first attempt looked like this:
var path = Path.Combine(Enviroment.WebRootPath, "Images", "Articles");
string dir = Directory.GetDirectories(path).First(d => Path.GetFileName(d).StartsWith(articleId.ToString()));
But if I where looking for a image with the id of 1, the line would give me a directory starting with 10_article.Name so obviously that wouldn't do.
I then tried:
string dir2 = Directory.GetDirectories(path).First(d => Path.GetFileName(d).Where(d => d.Split('_')[0] == articleId.ToString()));
I thought that would work, but I'm getting an error on the d.Split('_')[0]. It claims that d is now an char and therefore the method split can't be used. I understand that you somehow can save images as binary data in a SQL database and to keep images in the project folder might be dumb, as is my naming convention, but I'm curious how you could solve this. Any insight?
As I understand it, your structure is "/webroot/Images/Articles" (which remains constant), combined with /{articleId}+"_"+{articleName}/{imageName}, where the items in curly braces are variable, correct? How about something like this?
string imageRootFolder = Path.Combine(Enviroment.WebRootPath, "Images", "Articles");
string articleDir = Directory.GetDirectories(imageRootFolder).Where(dir => dir.StartsWith(articleId.ToString() + "_")).First();
List<string> pathsToImages = Directory.GetFiles(Path.Combine(imageRootFolder, articleDir)).ToList();
