AppendFileAsync(ConsensusClient, AppendFileParams, Action<IConsensusContext>?)

Appends content to an existing file.

Declaration
public static Task<TransactionReceipt> AppendFileAsync(this ConsensusClient client, AppendFileParams appendParameters, Action<IConsensusContext>? configure = null)
Parameters
Type Name Description
ConsensusClient client

The Consensus Node Client executing the file append.

AppendFileParams appendParameters

Configuration object identifying the file and contents to append.

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 the success of the operation.

Examples
await client.AppendFileAsync(new AppendFileParams
{
    File = createReceipt.File,
    Contents = Encoding.UTF8.GetBytes(" More content appended.")
});
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 append request as invalid or had missing data.
