# Value (XAttribute dynamic property)

Gets or sets the value of the XML attribute.

## Syntax

```xaml
attrib.Value
```

## Property value/return value

A <xref:System.String> containing the value of this attribute.

## Exceptions

|Exception type|Condition|
| - |---------------|
|<xref:System.ArgumentNullException>|When setting, the `value` is `null`.|

## Remarks

This property is equivalent to the <xref:System.Xml.Linq.XAttribute.Value%2A> property of the <xref:System.Xml.Linq.XAttribute?displayProperty=fullName> class, but this dynamic property also supports change notifications.
