	this TypeConverter<TItem> itemsConverter,

	bool nullable = true
)

VB

<ExtensionAttribute>
Public Shared Function ToIEnumerableConverter(Of TItem) ( 
	itemsConverter As TypeConverter(Of TItem),
	separator As String,
	Optional nullable As Boolean = true
) As TypeConverter(Of IEnumerable(Of TItem))

C++

public:
[ExtensionAttribute]
generic<typename TItem>
static TypeConverter<IEnumerable<TItem>^>^ ToIEnumerableConverter(
	TypeConverter<TItem>^ itemsConverter, 
	String^ separator, 
	bool nullable = true
)

F#

[<ExtensionAttribute>]
static member ToIEnumerableConverter : 
        itemsConverter : TypeConverter<'TItem> * 
        separator : string * 
        ?nullable : bool 
(* Defaults:
        let _nullable = defaultArg nullable true
*)
-> TypeConverter<IEnumerable<'TItem>>

Parameters

itemsConverter TypeConverterTItem: A TypeConverterT instance that converts the items.
separator String: A String that separates the items in a field of the CSV file. When parsing the CSV, separator will not be part of the results.
nullable Boolean (Optional): true to set DefaultValue to null; false to have EmptyTResult as DefaultValue.

Type Parameters

TItem: The Type of the items of the IEnumerableT objects that the newly created converter can convert.

Return Value

TypeConverterIEnumerableTItem
A new TypeConverterT instance that converts IEnumerableT. The value of its Throwing property is derived from itemsConverter.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type TypeConverterTItem. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The converter the method creates uses a simple string split and join operation. For nested CSV better use a simple StringConverter and initialize a separate CsvReader, CsvWriter, and CsvMapping to handle the nested items.

Exceptions

ArgumentNullException	itemsConverter or separator is null.
ArgumentException	separator is an Empty.
