File System Interactor

Purpose

The File System Interactor is a library designed to facilitate various file system operations, such as reading data from Excel files, interacting with file paths, and handling configuration settings. It provides a set of services and interfaces to streamline these tasks, making it easier for developers to work with file systems in their applications.

Features

• Configuration Service: Retrieve configuration values and column names from configuration settings.
• Excel Reader Service: Read data from Excel files based on specified column names.
• File Interaction Service: Select file paths and handle user input for file selection.
• File Path Service: Get base paths, file paths, and files with specific extensions.

Usage

Example 1: Reading Data from an Excel File

usingDovs.FileSystemInteractor.Interfaces;usingDovs.FileSystemInteractor.Services;usingSystem;usingSystem.Collections.Generic;classProgram{staticvoidMain(){IExcelReaderServiceexcelReaderService=newExcelReaderService();List<string>columnNames=newList<string>{"Name","Age","Email"};stringfilePath="path/to/excel/file.xlsx";try{List<Dictionary<string,string>>data=excelReaderService.ReadData(filePath,columnNames);foreach(varrowindata){Console.WriteLine($"Name: {row["Name"]}, Age: {row["Age"]}, Email: {row["Email"]}");}}catch(Exceptionex){Console.WriteLine($"Error: {ex.Message}");}}}

Example 2: Getting Configuration Values

usingDovs.FileSystemInteractor.Interfaces;usingDovs.FileSystemInteractor.Services;usingSystem;classProgram{staticvoidMain(){IConfigurationServiceconfigService=newConfigurationService();stringconfigValue=configService.GetConfigValue("SomeKey");Console.WriteLine($"Config Value: {configValue}");}}
