```

```vbnet

```

### Examples

```csharp
mergeBlockInfo.BlockMergingCondition = new List<TXTextControl.DocumentServer.DataShaping.FilterInstruction>();
mergeBlockInfo.Apply();
```

```vbnet
mergeBlockInfo.BlockMergingCondition = New List(Of TXTextControl.DocumentServer.DataShaping.FilterInstruction)()
