In C#, the System.IO
namespace provides Directory
and File
classes to perform these operations.
How to Search for Files in Directories in C#?
The easiest way to search directories and list files in C# is by using the Directory.GetFiles()
method, which retrieves an array of file paths matching a specified search pattern within a given directory.
How to use the Directory.GetFiles()
method to list all the files in a directory.
For example, using Directory.GetFiles()
in C#
string folderPath = @"C:\YourFolder"; string searchPattern = "*.txt"; // Search for .txt files, use "*" for all files. // Get all files recursively string[] files = Directory.GetFiles(folderPath, searchPattern, SearchOption.AllDirectories); foreach (string file in files) { Console.WriteLine(file); }
In this example, we specify a directory path in a string variable and use Directory.GetFiles()
to retrieve an array of file paths. A foreach
loop then iterates through the array, printing each file path to the console.
An alternative to search directories and list files in C# is the Directory.EnumerateFiles()
method, which returns an enumerable collection of file paths matching a specified search pattern.
How to use the Directory.EnumerateFiles()
method to list all the files in a directory.
For example, using Directory.EnumerateFiles()
string folderPath = @"C:\YourFolder"; var files = Directory.EnumerateFiles(folderPath, "*.*", SearchOption.AllDirectories).Where(file => file.EndsWith(".txt") || file.EndsWith(".log")); // Example filter foreach (var file in files) { Console.WriteLine(file); }
In this example, we specify a directory path in a string variable and uses Directory.EnumerateFiles()
to retrieve an enumerable collection of file paths. A foreach
loop iterates through the collection, printing each path to the console.
