Ecng.Common

A set of helpers and extensions that simplify everyday .NET tasks. The library contains convenient string utilities, a fast CSV parser, and a flexible converter able to transform many data types.

Purpose

Provide reusable helpers for core scenarios so that applications can stay concise and readable.

Key Features

• Rich string manipulation helpers
• High performance CSV parsing
• Flexible conversion between numerous types

String helpers

StringHelper adds small but handy methods:

"text".IsEmpty(); // bool check "{0} + {1} = {2}".Put(1, 2, 3); // simple formatting "a\nb".SplitByLineSeps(); // split by any newline

CSV parser

FastCsvReader reads CSV data without allocations:

var csv = "Id;Name\n1;Foo\n2;Bar"; var reader = new FastCsvReader(csv, StringHelper.N); while (reader.NextLine()) { var id = reader.ReadInt(); var name = reader.ReadString(); Console.WriteLine($"{id}: {name}"); }

Type converter

Converter easily casts objects across a wide range of types:

int number = "42".To<int>(); // string -> int byte[] data = number.To<byte[]>(); // int -> byte[] DateTime date = 1700L.To<DateTime>();

Additional converters can be registered through Converter.AddTypedConverter.
