public sealed class InvalidJsonException : IOException, ISerializable
Thrown when an attempt is made to parse invalid JSON, e.g. using
a non-string property key, or including a redundant comma. Parsing a protocol buffer
message represented in JSON using JsonParser can throw both this
exception and InvalidProtocolBufferException depending on the situation. This
exception is only thrown for "pure JSON" errors, whereas InvalidProtocolBufferException
is thrown when the JSON may be valid in and of itself, but cannot be parsed as a protocol buffer
message.
