MDLSoft.StringParsers

A powerful .NET library for parsing and writing structured text data using fixed-width and separator-based formats.

Features

• Fixed-width string parsing: Parse and write data with fixed column positions and lengths
• Separator-based parsing: Parse and write data using custom separators (CSV, TSV, etc.)
• Type conversion: Automatic conversion between string and target property types
• Custom validators: Add validation logic for parsed values
• Custom converters: Transform data during parsing and writing
• Built-in formatters: Common padding and formatting operations
• Strong typing: Fluent API with compile-time type checking

Quick Start

Fixed-Width Parsing

public class Person { public string Name { get; set; } public int Age { get; set; } } public class PersonFixedParser : FixedStringParser<Person> { public PersonFixedParser() { Define(p => p.Name, 0, 10).WithWriteSpaceRightPadder(); Define(p => p.Age, 10, 3).WithReadConverter<int>(s => int.Parse(s)) .WithWriteZeroLeftPadder(); ValidateDefinitions(); } } // Usage var parser = new PersonFixedParser(); var person = parser.Parse("John 025"); // Name: "John", Age: 25 var text = parser.Write(new Person { Name = "Ann", Age = 7 }); // "Ann 007"

Separator-Based Parsing

public class CsvPersonParser : SeparatorStringParser<Person> { public CsvPersonParser() : base(',') { Define(p => p.Name, 0); Define(p => p.Age, 1).WithReadConverter<int>(s => int.Parse(s)); } } // Usage var parser = new CsvPersonParser(); var person = parser.Parse("John,25"); // Name: "John", Age: 25
