Methods

GetContractBytecodeAsync(ConsensusClient, EntityId, CancellationToken, Action<IConsensusContext>?)

Retrieves the bytecode for the specified contract.

Declaration

public static Task<ReadOnlyMemory<byte>> GetContractBytecodeAsync(this ConsensusClient client, EntityId contract, CancellationToken cancellationToken = default, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client to query.
EntityId	contract	The address of the Contract.
CancellationToken	cancellationToken	Optional cancellation token.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<ReadOnlyMemory<byte>>	The bytecode for the specified contract instance.

Exceptions

Type	Condition
ArgumentOutOfRangeException	If required arguments are missing.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node rejected the request upon submission.

GetContractInfoAsync(ConsensusClient, EntityId, CancellationToken, Action<IConsensusContext>?)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client to query.
EntityId	contract	The address of the Contract instance to retrieve.
CancellationToken	cancellationToken	Optional cancellation token.
Action<IConsensusContext>	configure	Optional callback method providing an opportunity to modify the execution configuration for just this method call. It is executed prior to submitting the request to the network.

Returns

Type	Description
Task<ContractInfo>	A detailed description of the contract instance.

Exceptions

Type	Condition
ArgumentOutOfRangeException	If required arguments are missing.
InvalidOperationException	If required context configuration is missing.
