```csharp
[System.Obsolete]
public override void GetObjectData(SerializationInfo info, StreamingContext context)
```

When overridden in a derived class, sets the `System.Runtime.Serialization.SerializationInfo` with information about the exception.

### Parameters

- `info` (`SerializationInfo`): The `System.Runtime.Serialization.SerializationInfo` that holds the serialized object data about the exception being thrown.
- `context` (`StreamingContext`): The `System.Runtime.Serialization.StreamingContext` that contains contextual information about the source or destination.

### Exceptions

- `System.ArgumentNullException`: The `info` parameter is a null reference (`Nothing` in Visual Basic).
