XAttribute.Value Property

Syntax

'Declaration
Public Property Value As String

public string Value { get; set; }

Exceptions

Remarks

You can use this property to get or set the value of an attribute.

Setting this property will raise the Changed and the Changing events.

If you are getting the value and the attribute might not exist, it is more convenient to use the explicit conversion operators, and assign the attribute to a nullable type such as string or Nullable<T> of Int32. If the attribute does not exist, then the nullable type is set to nulla null reference (Nothing in Visual Basic). Before using this property, you must make sure that the Attribute method does not return nulla null reference (Nothing in Visual Basic).

Examples

The following example creates an element with an attribute. It then retrieves the value of the attribute, and then sets it.

Note that the Visual Basic example uses the XML attribute property.

Dim output As New StringBuilder
Dim root As XElement = <Root Att="content"/>
output.Append(root.@Att)
output.Append(Environment.NewLine)
root.@Att = "new text"
output.Append(root.@Att)
output.Append(Environment.NewLine)


OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
XElement root = new XElement("Root",
    new XAttribute("Att", "content")
);
XAttribute att = root.FirstAttribute;
output.Append(att.Value + Environment.NewLine);
att.Value = "new text";
output.Append(att.Value + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
