In addition, the package also provides the means to write high-performance code:\n\t- It allows you to parse ultra large CSV files because only one row of the file has to be in memory at a time.\n\t- It makes the fields of the CSV file available as `ReadOnlyMemory\u003cChar\u003e` instances. This avoids the allocation of numerous temporary strings.\n\t- It allows to parse value types without any boxing and unboxing and (when using a modern .NET version) without any allocation of temporary strings.\n\t- The `CsvOpts.DisableCaching` option allows reusing the same `CsvRecord` instance for each parsed row of the CSV file. This can avoid further allocations.\n\n(See [benchmark results](https://github.com/FolkerKinzel/CsvTools.Mappings/tree/master/src/Benchmarks/results) and the associated [benchmark code](https://github.com/FolkerKinzel/CsvTools.Mappings/tree/master/src/Benchmarks).)\n### Code Examples\n- [Object serialization with CSV](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Examples/ObjectSerializationExample.cs)\n- [Serializing and deserializing DataTables with CSV](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Examples/DataTableExample.cs)\n- [CSV data exchange with Excel](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Examples/ExcelExample.cs)\n- [High performance CSV parsing](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Benchmarks/CalculationReader_Performance.cs)\n- [Fastest way to write CSV](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Benchmarks/CalculationWriter_Performance.cs)\n- [Using the CsvOpts.DisableCaching option](https://github.com/FolkerKinzel/CsvTools/blob/master/src/Examples/DisableCachingExample.cs)\n- [Writing an own TypeConverter\u0026lt;T\u0026gt;](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Examples/Int128Converter.cs)\n- [CSV serialization with MultiColumnTypeConverter\u0026lt;T\u0026gt;](https://github.com/FolkerKinzel/CsvTools.Mappings/blob/master/src/Examples/MultiColumnConverterExample.cs)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffolkerkinzel%2Fcsvtools.mappings","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffolkerkinzel%2Fcsvtools.mappings","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffolkerkinzel%2Fcsvtools.mappings/lists"}
