This benchmark is generating a 100-line CSV file with 4 columns. Check the "SpeedBenchmarks" code.
Usage examples:
Install via Nuget Install-Package CsvExport
For "manual" CSV ad-hoc generation use this:
var myExport = new CsvExport();
myExport.AddRow();
myExport["Region"] = "Los Angeles, USA";
myExport["Sales"] = 100000;
myExport["Date Opened"] = new DateTime(2003, 12, 31);
myExport.AddRow();
myExport["Region"] = "Canberra \"in\" Australia";
myExport["Sales"] = 50000;
myExport["Date Opened"] = new DateTime(2005, 1, 1, 9, 30, 0);
///ASP.NET MVC action example
return File(myExport.ExportAsMemoryStream(), "text/csv", "results.csv");
For generating CSV out of a typed List<T> of objects:
public class Foo
{
public string Region { get; set; }
public int Sales { get; set; }
public DateTime DateOpened { get; set; }
}
var list = new List<Foo>
{
new Foo { Region = "Los Angeles", Sales = 123321, DateOpened = DateTime.Now },
new Foo { Region = "Canberra in Australia", Sales = 123321, DateOpened = DateTime.Now },
};
var myExport = new CsvExport();
myExport.AddRows(list);
string csv = myExport.Export();
Configuring is done via constructor parameters:
var myExport = new CsvExport(
columnSeparator: ",",
includeColumnSeparatorDefinitionPreamble: true, //Excel wants this in CSV files
includeHeaderRow: true
);
Also, methods ExportToFile and ExportAsMemoryStream and ExportToBytes offer an optional encoding parameter.
