Remarks

The method parameter type can be one of the following:

QueueClient
QueueMessage (out parameter)
String (out parameter)
byte[] (out parameter)
BinaryData (out parameter)
A user-defined type (out parameter, serialized as JSON)
Microsoft.Azure.WebJobs.ICollector`1 of these types (to enqueue multiple messages via Microsoft.Azure.WebJobs.ICollector`1.Add(`0)
Microsoft.Azure.WebJobs.IAsyncCollector`1 of these types (to enqueue multiple messages via Microsoft.Azure.WebJobs.IAsyncCollector`1.AddAsync(`0,System.Threading.CancellationToken)

By default the extension Base64-encodes outgoing messages. This behavior can be changed by setting MessageEncoding. For example, to configure Azure Functions to perform no base64 encoding/decoding, specify the following in host.json.

"extensions": {
  "queues": {
    "messageEncoding": "none"
  }
}
