Getting of a Node Data

To get a binary data associated with node, use GetDataAsync:

var getDataResult = await client.GetDataAsync(new GetDataRequest("/path/to/node"));
byte[]? data = getDataResult.Data;
NodeStat? stat = getDataResult.Stat;

If such node exists and has any data, it will be accessible through Data property of the result. Like ExistsResult, GetDataResult also contains NodeStat Stat object, which is not-null when node exists.
