Description

Serializes the JSON null value into an array of bytes.

ToBytes writes four bytes containing 'n', 'u', 'l', and 'l' characters into the specified <Data> byte array beginning from the <Offset> element. ToBytes returns the actual size of the <Data> array. ToBytes assumes that the byte container has sufficient capacity.

The parameters are described in the table below.

Parameter Meaning

Data

Byte container

Offset

Offset from which the JSON null value is serialized into the <Data> array.

Note: We recommend using EstimatedByteSize to determine the container capacity.

To serialize the JSON null value into a string, use the ToString method.
