Features

DateTimeUtils

Static utility class for common DateTime operations with ISO 8601 compliance:

• Get first day of week (using ISO 8601 standard where Monday is the first day)
• Get last day of week (using ISO 8601 standard where Sunday is the last day)
• Get ISO 8601 week number for a given date
• Get first and last day of month

PathUtils

Comprehensive static utility class for file path operations and manipulations:

• Path normalization for consistent comparison
• Drive letter normalization
• UNC path handling
• Path safety conversion for saving paths as filenames
• Relative path calculation
• Directory existence checks with auto-creation
• Safe path combination logic

Usage Examples

DateTimeUtils

using AaTurpin.Utilities;
using System;

// Get the first day (Monday) of the current week
DateTime monday = DateTimeUtils.GetFirstDayOfWeek(DateTime.Today);

// Get the last day (Sunday) of the current week
DateTime sunday = DateTimeUtils.GetLastDayOfWeek(DateTime.Today);

// Get the ISO 8601 week number
int weekNumber = DateTimeUtils.GetIso8601WeekOfYear(DateTime.Today);

// Get the first day of the current month
DateTime firstDayOfMonth = DateTimeUtils.GetFirstDayOfMonth(DateTime.Today);

// Get the last day of the current month
DateTime lastDayOfMonth = DateTimeUtils.GetLastDayOfMonth(DateTime.Today);

PathUtils

using AaTurpin.Utilities;
using System;

// Normalize paths for consistent comparison
string normalizedPath = PathUtils.NormalizePath(@"C:\Users\Username\Documents\");
// Result: "c:\users\username\documents"

// Extract server name from UNC path
string serverName = PathUtils.ExtractServerFromUncPath(@"\\Server01\Share\Folder");
// Result: "Server01"

// Convert standard path to filesystem-safe format (for storage)
string safePath = PathUtils.ConvertToFileSystemSafePath(@"C:\Project Files\Document.docx");
// Result: "C\Project Files\Document.docx"

// Restore original path from filesystem-safe format
string originalPath = PathUtils.RestoreFromFileSystemSafePath(@"C\Project Files\Document.docx");
// Result: "C:\Project Files\Document.docx"

// Get relative path
string relativePath = PathUtils.GetRelativePath(@"C:\Projects\MyProject\src\file.cs", @"C:\Projects\MyProject");
// Result: "src\file.cs"

// Ensure directory exists (creates if needed)
bool dirExists = PathUtils.EnsureDirectoryExists(@"C:\Temp\NewFolder");

// Ensure directory exists for a file (creates parent directory if needed)
bool parentDirExists = PathUtils.EnsureDirectoryExistsForFile(@"C:\Temp\NewFolder\file.txt");

// Combine path segments safely
string combinedPath = PathUtils.CombinePath("C:", "Users", "Username", "Documents");
// Result: "C:\Users\Username\Documents"
