# ResQ.Blockchain.MockNeoClient.RecordEvidenceAsync(ResQ.Blockchain.EvidenceRecord,System.Threading.CancellationToken)

### [ResQ.Blockchain](./ResQ.Blockchain.md "ResQ.Blockchain").[MockNeoClient](./ResQ.Blockchain.MockNeoClient.md "ResQ.Blockchain.MockNeoClient")

## MockNeoClient.RecordEvidenceAsync(EvidenceRecord, CancellationToken) Method

Records mock evidence metadata in memory.

```csharp theme={null}
public System.Threading.Tasks.Task<ResQ.Blockchain.TransactionResult> RecordEvidenceAsync(ResQ.Blockchain.EvidenceRecord evidence, System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));
```

#### Parameters

<a name="ResQ.Blockchain.MockNeoClient.RecordEvidenceAsync(ResQ.Blockchain.EvidenceRecord,System.Threading.CancellationToken).evidence" />

`evidence` [EvidenceRecord](./ResQ.Blockchain.EvidenceRecord.md "ResQ.Blockchain.EvidenceRecord")

The evidence record to record.

<a name="ResQ.Blockchain.MockNeoClient.RecordEvidenceAsync(ResQ.Blockchain.EvidenceRecord,System.Threading.CancellationToken).cancellationToken" />

`cancellationToken` [System.Threading.CancellationToken](https://learn.microsoft.com/en-us/dotnet/api/system.threading.cancellationtoken "System.Threading.CancellationToken")

Cancellation token for the operation.

Implements [RecordEvidenceAsync(EvidenceRecord, CancellationToken)](./ResQ.Blockchain.INeoClient.RecordEvidenceAsync\(ResQ.Blockchain.EvidenceRecord,System.Threading.CancellationToken\).md "ResQ.Blockchain.INeoClient.RecordEvidenceAsync(ResQ.Blockchain.EvidenceRecord, System.Threading.CancellationToken)")

#### Returns

[System.Threading.Tasks.Task\<](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")[TransactionResult](./ResQ.Blockchain.TransactionResult.md "ResQ.Blockchain.TransactionResult")[>](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")\
A [TransactionResult](./ResQ.Blockchain.TransactionResult.md "ResQ.Blockchain.TransactionResult") with a generated transaction hash and confirmed status.

### Example

```csharp theme={null}
var evidence = new EvidenceRecord(
    IncidentId: "inc-001",
    IpfsCid: "Qmabc123...",
    ContentType: "image/jpeg",
    SizeBytes: 1024567,
    Hash: "sha256:..."
);

var result = await mockClient.RecordEvidenceAsync(evidence);
// Logs: "MOCK: Recorded evidence for incident inc-001, CID: Qmabc123..., TxHash: 0x..."
```

### Remarks

This mock implementation generates a transaction hash and logs the evidence
details including the incident ID and IPFS CID.
