How can I get the files from the last created directory ?

Question

private void GetImagesFiles()  
        {  
            if (textBoxRadarPath.Text != "" || textBoxSatellitePath.Text != "")  
            {  
                if (Directory.Exists(textBoxRadarPath.Text))  
                {  
                    var t = CheckIfChildFoldersExist(textBoxRadarPath.Text);  
  
                    if (t != null)  
                    {  
                        filesRadar = System.IO.Directory.GetFiles(textBoxRadarPath.Text,  
                                      "*.gif", SearchOption.AllDirectories).OrderBy(x => x).ToArray();  
  
                        Array.Sort(filesRadar, new MyComparer(true));  
                    }  
                }  
  
                if (Directory.Exists(textBoxSatellitePath.Text))  
                {  
                    var t = CheckIfChildFoldersExist(textBoxSatellitePath.Text);  
  
                    if (t != null)  
                    {  
                        filesSatellite = System.IO.Directory.GetFiles(textBoxSatellitePath.Text,  
                                                      "*.gif", SearchOption.AllDirectories).OrderBy(x => x).ToArray();  
  
                        Array.Sort(filesSatellite, new MyComparer(true));  
                    }  
                }  
            }  
        }  

This get the files from all the directories.

In this case the most directory on the right side the last one :

The way the method is no I'm getting 245 images from all the directories for the radar and about 100 for the satellite images.

but I want to get only from the last directory of the radar and satellite.

You could use DirectoryInfo to get the creation time, order & then just select the first sub-directory. Once you have the directory you can get your files by pattern as you currently are:

string rootPath = Environment.ExpandEnvironmentVariables(@"%USERPROFILE%\Desktop");

DirectoryInfo directory = new DirectoryInfo(rootPath).GetDirectories()
    .OrderByDescending(d => d.CreationTimeUtc)
    .First();

FileInfo[] files = directory.GetFiles("*.gif");

You're getting all files in all folders because you're passing SearchOption.AllDirectories to GetFiles on the root folder which will return files past the top folder level.
