Declaration

public static string JoinAsString<T>(this IEnumerable<T> source, string separator)

Parameters

Type	Name	Description
IEnumerable<T>	source	A collection that contains the objects to concatenate.
System.String	separator	The string to use as a separator. separator is included in the returned string only if values has more than one element.

System.Boolean	condition	A boolean value
Func<T, System.Boolean>	predicate	Predicate to filter the enumerable

Returns

Type	Description
IEnumerable<T>	Filtered or not filtered enumerable based on condition

Type Parameters
