Declaration

public static Task<FileReceipt> CreateFileAsync(this ConsensusClient client, CreateFileParams createParameters, Action<IConsensusContext>? configure = null)

Parameters

Type	Name	Description
ConsensusClient	client	The Consensus Node Client executing the file create.
CreateFileParams	createParameters	File creation parameters specifying contents and ownership of the file.
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.

Task<FileReceipt>	A transaction receipt with a description of the newly created file.

Examples

var createReceipt = await client.CreateFileAsync(new CreateFileParams
{
    Contents = Encoding.UTF8.GetBytes("Hello from Hiero SDK!"),
    Endorsements = new[] { payerEndorsement },
    Memo = "Sample file"
});
Console.WriteLine($"File created: {createReceipt.File}");

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 create request as invalid or had missing data.
