ValueWriterReadNullableT Method

public static T ReadNullable<T>(
	BinaryReader reader
)
where T : class

Public Shared Function ReadNullable(Of T As Class) ( 
	reader As BinaryReader
) As T

public:
generic<typename T>
where T : ref class
static T ReadNullable(
	BinaryReader^ reader
)

static member ReadNullable : 
        reader : BinaryReader -> 'T  when 'T : not struct

Parameters

reader  BinaryReader

The reader to read the value from.

Type Parameters

T

The type of the object to read.

Return Value

A Boolean is read from reader to see if the value is . If it is , nothing else will be read.

If the type implements IWritable, a new instance is created and Read(BinaryReader) is used to read the value. If it does not, IValueWriterT is used to read the value.

This method will always create a new instance, even if the type implements IWritable, so should not be used in scenarios where you wish to support record reuse.
