Get Image file from folder in FileInfo

Question

I am making a console application and from a particular folder I want to get only the images with specific extension.

Below code I am trying but it's retrieving all the files from the particular path.

string[] extensions = { ".jpg", ".jpeg", ".png", ".gif", ".tif" };
FileInfo[] files = new DirectoryInfo(SourcePath).GetFiles("*.*", SearchOption.AllDirectories);

How can I set extension on FileInfo[]?

Updated Issue

Answer

List<String> ImageFiles = Directory.GetFiles(SourcePath, "*.*",
             SearchOption.AllDirectories)
            .Where(file => new string[] { ".jpg", ".jpeg", ".png", ".gif", ".tif" }
            .Contains(Path.GetExtension(file)))
            .ToList();
            List<FileInfo> files = new List<FileInfo>();
            foreach (string filess in ImageFiles)
            {
                string replace = filess.Replace(@"\", "/");
                files.Add(new FileInfo(replace.Split('/').Last()));
            }

here how Can I get rid from for each loop as I am only needing file name and not the whole path

Right now there is absolutely no connection between your `extensions` and the call to `GetFiles`. You'll have to either filter the list of files or iterate the extensions. — Manfred Radlwimmer, Dec 28 '17 at 11:19

Please use the below code.

 List<String> ImageFiles = Directory.GetFiles(DirPath, "*.*",
                 SearchOption.AllDirectories)
                .Where(file => new string[] { ".jpg", ".jpeg", ".png", ".gif", ".tif" }
                .Contains(Path.GetExtension(file)))
                .ToList();
                List<FileInfo> images = new List<FileInfo>();
                foreach (string fileName in ImageFiles)
                {
                images.Add(new FileInfo(fileName));
                }

Is it not possible to get data in FileInfo[] files? – Mitesh Jain Dec 28 '17 at 11:31
Can it be done with out foreach loop and can I only get the file names instead of getting full path? – Mitesh Jain Dec 29 '17 at 11:23
"Regex.Match(fileName, @"[^\\]*$").Value" Using the regular expression you will get the filename without path. – Aman Bachas Dec 29 '17 at 12:00

Try following code snippet . Updated the answer as per your question

void Main()
{


List<string> ext = new List<string> { ".jpg", ".jpeg", ".png", ".gif", ".tif" }; 
FileInfo[] files = new DirectoryInfo(@"c:\temp").EnumerateFiles("*.*", SearchOption.AllDirectories) 
.Where(path => ext.Contains(Path.GetExtension(path.Name))) 
.Select(x => new FileInfo(x.FullName)).ToArray();
}

// Define other methods and classes here

A `ToLower` would also include files like `test.JPG`. Also the `GetExtensions` method includes the `.` so it would have to be present in `ext` too. – Manfred Radlwimmer Dec 28 '17 at 11:22

Yes it's possible FileInfo[] smFiles = di.GetFiles("*.jpg"); foreach (FileInfo fi in smFiles) { } – santosh singh Dec 28 '17 at 11:34
GetFiles returns FileInfo. what is your requirement – santosh singh Dec 28 '17 at 11:42

I think it will be better to use Directory.EnumerateFiles instead of GetFiles. EnumerateFiles method is not waiting until all files are loaded. Which can be more efficient with large number of files.

void Main()
{
    string[] ext = new List<string> {".jpg", ".jpeg", ".png", ".gif", ".tif"};
    FileInfo[] files = new DirectoryInfo(SourcePath).EnumerateFiles(@"C:\temp", "*.*", SearchOption.AllDirectories)
     .Where(path => ext.Contains(Path.GetExtension(path.ToLower()));
}

UPDATE:

Answer to updated question.

    var ImageFilenames = Directory.EnumerateFiles(SourcePath, "*.*",
     SearchOption.AllDirectories)
    .Where(file => new string[] { ".jpg", ".jpeg", ".png", ".gif", ".tif" }
    .Contains(Path.GetExtension(file)))
    .Select(p => p.Substring(p.LastIndexOf('\\') + 1));

What is it? What issue? – dropoutcoder Dec 29 '17 at 10:35 — dropoutcoder, Dec 29 '17 at 10:35
