Example
Object serialization with CSV:
C#
using FolkerKinzel.CsvTools;
using FolkerKinzel.CsvTools.Mappings;
using FolkerKinzel.CsvTools.Mappings.TypeConverters;
namespace Benchmarks;
internal static partial class CalculationWriter
{
internal static string WriteDefault(Calculation[] data)
{
var doubleConverter = new DoubleConverter();
CsvMapping mapping = CsvMappingBuilder
.Create()
.AddProperty("First", doubleConverter)
.AddProperty("Operator", new CharConverter())
.AddProperty("Second", doubleConverter)
.AddProperty("Result", doubleConverter)
.Build();
return data.ToCsv(
mapping,
static (calculation, mapping) =>
{
mapping.First = calculation.First;
mapping.Operator = calculation.Operator;
mapping.Second = calculation.Second;
mapping.Result = calculation.Result;
});
}
}Exceptions
| ArgumentException | format is "D", "d", "X", or "x". |
