Testing

To guarantee its stability Extend contains over 2400 unit tests. Each method has test with different input parameters, including invalid values to test the exception handling.

Example

Array to list using a selector:

var myArray = new[] {"1", "2", "3"};
var intValues = myArray.ToList(x => x.ToInt32());

Action executing based on boolean values:

var successful = SaveData();
successful.IfTrue(() => DisplaySuccess(), () => DisplayFailure());
successful.IfFalse(() => DisplayFailure(), () => DisplaySuccess());

Add to collection:

var list = new List<String>();
list.AddIf(x => new Random().Next(0, 10) % 2 == 0, "Value");
list.AddIfNotContains( "Value #1");
list.AddRange("Value #1", "Value #2", "Value #3");
list.AddRangeIfNotContains("Value #1", "Value #2", "Value #3");
list.AddRangeIf(x => new Random().Next(0, 10) % 2 == 0, "Value", "Value #2", "Value #3");

Working with dictionaries

var dictionary = new Dictionary<String, String>();
dictionary.AddOrUpdate("Key", "Value");
dictionary.AddRange(new Dictionary<String, String>
{
	{ "Key1", "Value1" },
	{ "Key2", "Value2" }
});
dictionary.GetOrAdd("Key", () => "Value");
var keyValueCsv = dictionary.StringJoin("=", ", ");

Working with IEnumerable:

var list = new List<String>();
var containsNotNullValues = list.AnyAndNotNull();
var distinctValues = list.Distinct(x => x.Substring(0, 2));
list.ForEach(x => { });
list.ForEachReverse(x => list.Remove(x));

Working with DateTime:

var dateTime = DateTime.Now;
var stringValue = dateTime.ToLongDateShortTimeString();
var elapsed = dateTime.Elapsed();
var isFuture = dateTime.IsFuture();
var weekend = dateTime.IsWeekendDay();

String templates:

"Today is the: {Today}".FormatWithObject( new { Today = DateTime.Now } );

"Today is the: {Today}".FormatWithObject( new Dictionary<String, Object> { { "Today", DateTime.Now } } );
