Get
Get a list of a specific event’s occurrences emitted from the contract during a specified time period.
Usage
Provide the name of the event, and an optional filter to define the time period to get events for.
// Define the shape of the event data
public struct MyEvent
{
public string from;
public string to;
public string tokenId;
}
// Get all emitted events
var data = await contract.events.Get<MyEvent>("eventName");
Configuration
structure (generic type)
The event data structure to deserialize into, i.e. what shape the event data should be in.
eventName
The name of the event to get logs for.
In Solidity, an event is triggered by the emit
keyword.
// An example Solidity contract
emit Transfer(); // Triggering event
To listen to this event, use the name of the event as it appears in the contract.
var data = await contract.events.Get<MyEvent>("Transfer");
filters (optional)
An optional object containing the fromBlock
and toBlock
numbers for the time period to get events for.
The order
field indicates the ordering of the events; desc
(descending) or asc
(ascending).
The filters
field allows you to filter on indexed event parameters.
The default fromBlock
is 0
and the default toBlock
is latest
.
var data = await contract.events.Get<MyEvent>("eventName", new EventQueryOptions()
{
fromBlock = 0,
toBlock = 1000000,
order = "desc",
})
