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.
