# ResQ.Blockchain.MockNeoClient.GetBlockHeightAsync(System.Threading.CancellationToken)

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

## MockNeoClient.GetBlockHeightAsync(CancellationToken) Method

Gets the current mock block height.

```csharp theme={null}
public System.Threading.Tasks.Task<ulong> GetBlockHeightAsync(System.Threading.CancellationToken cancellationToken=default(System.Threading.CancellationToken));
```

#### Parameters

<a name="ResQ.Blockchain.MockNeoClient.GetBlockHeightAsync(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 [GetBlockHeightAsync(CancellationToken)](./ResQ.Blockchain.INeoClient.GetBlockHeightAsync\(System.Threading.CancellationToken\).md "ResQ.Blockchain.INeoClient.GetBlockHeightAsync(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")[System.UInt64](https://learn.microsoft.com/en-us/dotnet/api/system.uint64 "System.UInt64")[>](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 "System.Threading.Tasks.Task`1")\
The current block height, starting at 1,000,000 and incrementing with each transaction.

### Example

```csharp theme={null}
var initialHeight = await mockClient.GetBlockHeightAsync();
// Returns: 1000000

await mockClient.RecordEventAsync(evt);

var newHeight = await mockClient.GetBlockHeightAsync();
// Returns: 1000001
```

### Remarks

The block height starts at 1,000,000 and increases by 1 for each recorded transaction.
This simulates blockchain growth without requiring an actual network connection.
