# ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string)

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

## EvidenceRecord(string, string, string, long, string) Constructor

Represents evidence metadata linked to IPFS storage.

```csharp theme={null}
public EvidenceRecord(string IncidentId, string IpfsCid, string ContentType, long SizeBytes, string Hash);
```

#### Parameters

<a name="ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string).IncidentId" />

`IncidentId` [System.String](https://learn.microsoft.com/en-us/dotnet/api/system.string "System.String")

ID of the incident this evidence belongs to.

<a name="ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string).IpfsCid" />

`IpfsCid` [System.String](https://learn.microsoft.com/en-us/dotnet/api/system.string "System.String")

IPFS Content Identifier for the evidence file.

<a name="ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string).ContentType" />

`ContentType` [System.String](https://learn.microsoft.com/en-us/dotnet/api/system.string "System.String")

MIME type of the evidence (e.g., "image/jpeg", "video/mp4").

<a name="ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string).SizeBytes" />

`SizeBytes` [System.Int64](https://learn.microsoft.com/en-us/dotnet/api/system.int64 "System.Int64")

Size of the evidence file in bytes.

<a name="ResQ.Blockchain.EvidenceRecord.EvidenceRecord(string,string,string,long,string).Hash" />

`Hash` [System.String](https://learn.microsoft.com/en-us/dotnet/api/system.string "System.String")

Cryptographic hash of the evidence content for verification.

### Example

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

var result = await neoClient.RecordEvidenceAsync(evidence);
```

### Remarks

Evidence records link incidents to their associated evidence stored on IPFS.
The hash field provides a content verification mechanism to ensure evidence
integrity when retrieved from IPFS.
