## AbsoluteUriAttribute Class

Marks a [System\.Uri](https://learn.microsoft.com/en-us/dotnet/api/system.uri 'System\.Uri')\-typed property, field, or parameter as having to be an absolute URI\.
Relative URIs and values that do not parse as absolute are treated as invalid by validators that
honor this attribute; null values are not flagged here, leave that to [System\.ComponentModel\.DataAnnotations\.RequiredAttribute](https://learn.microsoft.com/en-us/dotnet/api/system.componentmodel.dataannotations.requiredattribute 'System\.ComponentModel\.DataAnnotations\.RequiredAttribute')\.

```csharp
public class AbsoluteUriAttribute : System.Attribute
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → [System\.Attribute](https://learn.microsoft.com/en-us/dotnet/api/system.attribute 'System\.Attribute') → AbsoluteUriAttribute
