Methods

SystemRestoreContractAsync(ConsensusClient, SystemRestoreContractParams, Action<IConsensusContext>?)

Restores a contract to the network via Administrative Restore

Declaration

public static Task<TransactionReceipt> SystemRestoreContractAsync(this ConsensusClient client, SystemRestoreContractParams restoreParams, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client orchestrating the administrative command.
SystemRestoreContractParams	restoreParams	The parameters for the system restore operation, including the contract address to restore.
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<TransactionReceipt>	A transaction receipt indicating success of the contract restoration.

Examples

// Undo a previous SystemDeleteContractAsync within the grace window.
var receipt = await client.SystemRestoreContractAsync(new SystemRestoreContractParams
{
    Contract = contract
});
Console.WriteLine($"System restore status: {receipt.Status}");

Exceptions

Type	Condition
ArgumentException	If required arguments are missing or invalid.
InvalidOperationException	If required context configuration is missing.
PrecheckException	If the gateway node refused the transaction. Only a code about the transaction itself proves it did not execute; any other code leaves the outcome unknown, so settle it by its transaction id on a mirror node rather than resubmitting it (see PrecheckException).
ConsensusException	If the outcome could not be confirmed: the transaction may have executed, so settle it by its transaction id on a mirror node rather than resubmitting it.
TransactionException	If the network rejected the restore request as invalid or had missing data.
