Utils Class

The Utils class provides a collection of static utility methods for working with files and directories.

Methods

IsNullOrEmpty

public static bool IsNullOrEmpty(string fileName)

Determines whether the specified file exists and has a length greater than zero.

• fileName: The name of the file to check.

Returns true if the file exists and has a length greater than zero; otherwise, false.

ReadAllTextAsync

public static async Task<string> ReadAllTextAsync(string path, Encoding? encoding = null)

Asynchronously reads the entire contents of a text file and returns the result as a string.

• path: The path to the file to read.
• encoding: The encoding to use when reading the file. If null, the default encoding for the operating system is used.

Returns a Task representing the completion of the file read operation. The result is the contents of the file as a string.

ResetFile

public static string ResetFile(params string[] paths)

Resets the contents of the specified files by overwriting them with an empty string.

• paths: The paths of the files to reset.

Returns a string containing the path(s) of the file(s) that were reset.

ResetDirectory

public static string ResetDirectory(params string[] paths)

Determines whether the specified directories exists and create new, empty directories in their place if not.

• paths: The paths of the directories to reset.

Returns a string containing the path(s) of the directory(s) that were reset.

WriteAllText

public static async Task<string> WriteAllText(string path, string content, Encoding? encoding = null)

Writes the specified content to a file at the specified path. If the file does not exist, it is created; otherwise, its contents are overwritten.

• path: The path of the file to write to.
• content: The content to write to the file.
• encoding: The character encoding to use when writing the file. If not specified, the default encoding is used.

Returns a task representing the asynchronous write operation.

Example Usage

using System.Text;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        // Check if file exists and has a length greater than zero
        bool fileExistsAndNotEmpty = Utils.IsNullOrEmpty("example.txt");

        // Read the entire contents of a text file as a string
        string fileContents = await Utils.ReadAllTextAsync("example.txt", Encoding.UTF8);

        // Reset the contents of a file
        string resetFilePath = Utils.ResetFile("example.txt");

        // Reset the contents of a directory
        string resetDirectoryPath = Utils.ResetDirectory("example_directory");

        // Write text to a file
        await Utils.WriteAllText("example.txt", "Hello, world!", Encoding.UTF8);
    }
}
