## FeatureAttribute.DefaultValue property

Gets or sets a value for the attribute, that indicates missing data.

```csharp
public object DefaultValue { get; set; }
```

### Exceptions

| exception | condition |
| --- | --- |
| InvalidOperationException | The attribute is locked. |
| InvalidOperationException | The attribute does not allow `null` values. |

## Remarks

This is the value representing a missing piece of information, when an attribute does not allow the `null` value. For attributes that do allow `null` values ([`CanBeNull`](../canbenull/) == `true`), `DefaultValue` is `null` unless explicitly changed.
