How to create a recursive function to copy all files and folders

Question

I am trying to create a function that will recursively copy a source folder and all files and folders inside of it to a different location.

At the moment, I have to define each folder within the main folder, which is making the code bloated and redundant.

What's a more efficient way of doing this?

Solution 1

Source: C# - Copy files and folders recursively from source to destination folder in c-sharp

public static void CopyFolder(string sourceFolder, string destFolder)  
{  
    if (!Directory.Exists(destFolder))  
        Directory.CreateDirectory(destFolder); 

    string[] files = Directory.GetFiles(sourceFolder);  
    foreach (string file in files)  
    {  
        string name = Path.GetFileName(file);  
        string dest = Path.Combine(destFolder, name);  
        File.Copy(file, dest);  
    }  
    string[] folders = Directory.GetDirectories(sourceFolder);  
    foreach (string folder in folders)  
    {  
        string name = Path.GetFileName(folder);  
        string dest = Path.Combine(destFolder, name);  
        CopyFolder(folder, dest);  
    }  
}

Solution 2

Do it this way

 void Copy(string sourceDir, string targetDir)
 {
   Directory.CreateDirectory(targetDir);
   foreach (var file in Directory.GetFiles(sourceDir))
       File.Copy(file, Path.Combine(targetDir, Path.GetFileName(file)));

   foreach (var directory in Directory.GetDirectories(sourceDir))
       Copy(directory, Path.Combine(targetDir, Path.GetFileName(directory)));
 }
